Altogether about 232 eruptions have been recorded, and of these the greater number took place in the southern districts. This may perhaps be accounted for by the fact that j.a.panese civilization advanced from the south. In consequence of this, records were made of various phenomena in the south when the northern regions were still unknown and unexplored.
The most famous of the active volcanoes is Asama-yama in Shinano. The earliest eruption of this mountain of which record now exists seems to have been in 1650. After that it was only feebly active for 133 years, when there occurred a very severe eruption in 1783. Even as late as 1870 there was a considerable emission of volcanic matter, at which time also violent shocks of earthquake were felt at Yokohama. The crater is very deep, with irregular rocky walls of a sulphur character, from apertures in which fumes are constantly sent forth.
Probably the earliest authentic instance of an earthquake in j.a.pan is that which is said to have occurred in 416 A.D., when the imperial palace at Kioto was thrown to the ground. Again, in 599, the buildings throughout the province of Yamato were all destroyed, and special prayers were ordered to be offered up to the deity of earthquakes. In 679 a tremendous shock caused many fissures to open in the provinces of Chikuzen and Chikugo, in Kiushiu; the largest of these chasms was over four miles in length and about twenty feet in width. In 829 the northern province of Dewa was visited in a similar manner; the castle of Akita was overthrown, deep rifts were formed in the ground in every direction, and the Akita river was dried up.
To descend to more recent instances, in 1702 the lofty walls of the outside and inside moats of the castle of Yeddo were destroyed, tidal waves broke along the coast in the vicinity, and the road leading through the famous pa.s.s of Hakone, in the hills to the east of Fuji-yama was closed up by the alteration in the surface of the earth.
A period of unusual activity was between the years 1780 and 1800, a time when there was great activity elsewhere on the globe. It was during this period that Mount Unsen was blown up, and from 27,000 to 53,000 persons (according to different accounts) perished; that many islands were formed in the Satsuma sea; that Sakura-jima threw out so much pumice material that it was possible to walk a distance of twenty-three miles upon the floating debris in the sea; and that Asama ejected so many blocks of stone--one of which is said to have been forty-two feet in diameter--and a lava-stream sixty-eight kilometres in length.
In 1854 an earthquake destroyed the town of Shimoda, in the province of Idzu, and a Russian frigate, lying in the harbor at the time, was so severely damaged by the waves caused by the shock that she had to be abandoned. In 1855 came a great earthquake which was felt most severely at Yedo, though its destructive power extended for some distance to the west along the line of the Tokaido. It is stated that on this occasion there were in all 14,241 dwelling houses and 1,649 fire proof store houses overturned in the city, and a destructive fire which raged at the same time further increased the loss of life and property.
What was possibly the gravest disaster of its cla.s.s in this land of volcanoes, since the terrible eruptions which came in the twenty years ending in 1800, occurred in the Bandai-san region in northern j.a.pan, on July 15, 1888. At about eight o"clock in the morning of that day, almost in the twinkling of an eye, Little Bandai-san was blown into the air, and wiped out of the map of j.a.pan. A few moments later its debris had buried or devastated the surrounding country for miles, and a dozen or more of upland hamlets had been overwhelmed in the earthen deluge, or wrecked by other phenomena attending the outburst. Several hundreds of people had met with sudden and terrible death; scores of others had been injured; and the long roll of disaster included the destruction of horses and cattle, damming up of rivers, and laying waste of large tracts of rice-land and mulberry groves.
A small party was organized in Tokio to visit the scene. As the travelers approached the mountain, they were told that twenty miles in a straight line from Bandai-san no noise or earthquake was experienced on the 15th, but mist and gloom prevailed for about seven hours, the result of a shower of impalpable blue-gray ash, which fell to a depth of half an inch, and greatly puzzled the inhabitants. An ascent of about 3,000 feet was made to the back of the newly formed crater, so as to obtain a clear view of it and of the country which had been overwhelmed. Only on nearing the end of the ascent was the party again brought face to face with signs of the explosion. Here, besides the rain of fine, gray, ashen mud which had fallen on and still covered the ground and all vegetation, they came upon a number of freshly opened pits, evidently in some way the work of the volcano. Ascending the last steep rise to the ridge behind Little Bandai-san, signs of the great disaster grew in number and intensity.
The London Times correspondent, who was one of the party, wrote: "Fetid vapors swept over us, emanating from evil looking pools. Great trees, torn up by their roots, lay all around; and the whole face of the mountain wore the look of having been withered by some fierce and baleful blast. A few minutes further and we had gained the crest of the narrow ridge, and now, for the first time, looked forth upon the sight we had come to see. I hardly know which to p.r.o.nounce the more astonishing, the prospect that now opened before our eyes or the suddenness with which it burst upon us. To the former no more fitting phrase, perhaps, can be applied than that of absolute, unredeemed desolation--so intense, so sad, and so bewildering that I despair of describing it adequately in detail.
"On our right, a little above us, rose the in-curved rear wall of what, eight days before, had been s...o...b..ndai-san, a ragged, almost sheer cliff, falling, with scarce a break, to a depth of fully 600 feet. In front of the cliff everything had been blown away and scattered over the face of the country before it, in a roughly fan-shaped deposit of for the most part unknown depth--deep enough, however, to erase every landmark, and conceal every feature of the deluged area. At the foot of the cliff, clouds of suffocating steam rose ceaselessly and angrily, and with loud roaring, from two great fissures in the crater bed, and now and then a.s.sailed us with their h.e.l.lish odor. To our eyes, the base, denuded by the explosion, seemed to cover a s.p.a.ce of between three and four square miles. This, however, can only be rough conjecture. Equally vague must be all present attempts to determine the volume of the disrupted matter. Yet, if we a.s.sume, as a very moderate calculation, that the mean depth of the debris covering a buried area of thirty square miles is not less than fifteen feet, we find that the work achieved by this great mine of Nature"s firing was the upheaval and wide distribution of no fewer than 700,000,000 tons of earth, rocks, and other ponderous material.
The real figure is probably very much greater."
The desolation beyond the crater, and the mighty ma.s.s thrown out by the volcano which covered the earth, were almost incredible. "Down the slopes of Bandai-san, across the valley of the Nagase-gawa, choking up the river, and stretching beyond it to the foothills, five or six miles away, swept a vast, billowy sheet of ash-covered earth or mud, obliterating every foot of the erstwhile smiling landscape. Here and there the eyes rested on huge, disordered heaps of rocky debris, in the distance resembling nothing so much as the giant, concrete, black substructure of some modern breakwater. It was curious to see on the farther side the sharp line of demarkation between the brown sea of mud and the green forests on which it had encroached; or, again, the lakes formed in every tributary glen of the Nagase-gawa by the ma.s.sive dams so suddenly raised against the pa.s.sage of their stream waters.
One lake was conspicuous among the rest. It was there that the Nagase-gawa itself had been arrested at its issue from a narrow pa.s.s by a monster barrier of disrupted matter thrown right across its course. Neither living thing nor any sign of life could be discerned over the whole expanse. All was dismally silent and solitary. Beneath it, however, lay half a score of hamlets, and hundreds of corpses of men, women and children, who had been overtaken by swift and painful deaths."
Although the little village of Nagasaka was comparatively uninjured, nearly all its able-bodied inhabitants lost their lives in a manner which shows the extraordinary speed with which the mud-stream flowed.
When Little Bandai-san blew up, and hot ashes and sand began to fall, the young and strong fled panic-stricken across the fields, making for the opposite hills by paths well known to all. A minute later came a thick darkness, as of midnight. Blinded by this, and dazed by the falling debris and other horrors of the scene, their steps, probably also their senses, failed them. And before the light returned every soul was caught by a swift bore of soft mud, which, rushing down the valley bed, overwhelmed them in a fate more horrible and not less sudden than that of Pharaoh and his host. None escaped save those who stayed at home--mostly the old and very young.
A terrible earthquake convulsed central j.a.pan on the morning of October 25, 1891. The waves of disturbance traversed thirty-one provinces, over which the earth"s crust was violently shaken for ten minutes together, while slighter shocks were felt for a distance of 400 miles to the north, and traveled under the sea a like distance, making themselves felt in a neighboring island. In Tokio itself, though 170 miles from the center of disturbance, it produced an earthquake greater than any felt for nearly forty years, lasting twelve minutes. Owing, however, to the character of the movement, which was a comparatively slow oscillation, the damage was confined to the wrecking of some roofs and chimneys. Very different were its results in the central zone of agitation, concerning which a correspondent wrote as follows:
"There was a noise as of underground artillery, a shake, a second shake, and in less than thirty seconds the Nagoya-Gifu plain, covering an area of 1,200 square miles, became a sea of waves, more than 40,000 houses fell, and thousands of people lost their lives. The sequence of events was approximately as follows: To commence at Tokio, the capital, which is some 200 miles from the scene of the disaster, on October 25th, very early in the morning, the inhabitants were alarmed by a long, easy swaying of the ground, and many sought refuge outside their doors. There were no shocks, but the ground moved back and forth, swung round, and rose and fell with the easy, gentle motion of a raft upon an ocean swell. Many became dizzy, and some were seized with nausea."
These indications, together with the movements of the seismographs, denoted a disturbance at a considerable distance, but the first surmise that it was located under the Pacific Ocean, was unfortunately incorrect. The scene of the catastrophe was indicated only by tidings from its outskirts, as all direct news was cut off by the interruption of railway and telegraphic communication. An exploratory and relief party started on the second day from Tokio, not knowing how far they would be able to proceed by train, and the correspondent who accompanied them thus described his experiences:
"Leaving Tokio by a night train, early next morning we were at Hamamatsu, 137 miles distant from Tokio, on the outside edge of the destructive area. Here, although the motion had been sufficiently severe to destroy some small warehouses, to displace the posts supporting the heavy roof of a temple, and to ruffle a few tiles along the eaves of the houses, nothing serious had occurred. At one point, owing to the lateral spreading of an embankment, there had been a slight sinkage of the line, and we had to proceed with caution.
Crossing the entrance to the beautiful lake of Hamana Ko, which tradition says was joined to the sea by the breaking of a sand-spit by the sea waves accompanying an earthquake in 1498, we rose from the rice fields and pa.s.sed over a country of hill and rock. Further along the line signs of violent movement became more numerous. Huge stone lanterns at the entrances of temples had been rotated or overturned, roofs had lost their tiles, especially along the ridge, sinkages in the line became numerous, and although there was yet another rock barrier between us and the plain of great destruction, it was evident that we were in an area where earth movements had been violent."
The theatre of maximum destruction was a plain, dotted with villages and homesteads, supporting, under the garden-like culture of j.a.pan, 500 and 800 inhabitants to the square mile, and containing two cities, Nagoya and Gifu, with populations respectively of 162,000 and 30,000, giving probably a round total of half a million human beings. Within about twelve miles of Gifu, a subsidence on a vast scale took place, engulfing a whole range of hills, while over lesser areas the soil in many places slipped down, carrying with it dwellings and their inmates. Gifu was a total wreck, devastated by ruin and conflagration, causing the destruction of half its houses. Ogaki, nine miles to the west, fared even worse, for here only 113 out of 4,434 houses remained standing, and one-tenth of the population were killed or wounded. In one temple, where service was being held, only two out of the entire congregation escaped.
Nagoya, too, suffered heavily, and thousands of houses collapsed. The damage at this place was produced by three violent shocks in quick succession, preceded by a deep, booming sound. During the succeeding 206 hours, 6,600 earth spasms of greater or less intensity were felt at increasing intervals, occurring in the beginning probably at the rate of one a minute. The inhabitants were driven to bivouac in rude shelters in the streets, and there was great suffering among the injured, to whom it was impossible to give proper care for many days after the disaster. Some estimates placed the figure of the killed and wounded as high as 24,000, whilst not less than 300,000 were rendered homeless.
Owing to the frequency of earthquake shocks in j.a.pan, the study of their causes and effects has had a great deal of attention there since the introduction of modern science into the island empire. The j.a.panese have proved as energetic in this direction as they are in purely material progress on the lines of western civilization, and already they are recognized as the most advanced of all people in their study of seismology and its accompanying phenomena.
CHAPTER XXIX.
KRAKATOA, THE GREATEST OF VOLCANIC EXPLOSIONS.
BY TRUMBULL WHITE.
=The Volcano That Blew Its Own Head Off--The Terrific Crash Heard Three Thousand Miles--Atmospheric Waves Travel Seven Times Around the Earth--A Pillar of Dust Seventeen Miles High--Islands of the Malay Archipelago Blotted Out of Existence--Native Villages Annihilated--Other Disastrous Upheavals in the East Indies.=
One of the fairest regions of the world is the Malay Archipelago of the East Indies. Here nature is prodigal with her gifts to man, and the cocoa-palm, cinnamon and other trees flourish, and rice, cotton, the sugar cane and tobacco yield their increase under cultivation. But beneath these scenes of loveliness, there are terrific energies, for this region is a focus of intense volcanic action. In the Sunda strait, between Sumatra and Java, there lies a group of small volcanic islands, the largest of which is Krakatoa. It forms part of the "basal wreck" of a large submarine volcano, whose visible edges are also represented by Velaten and Lang islands.
For two hundred years the igneous forces beneath Krakatoa remained dormant; but in September, 1880, premonitory shocks of earthquake were heard in the neighborhood. At length the inhabitants of Batavia and Bintenzorg were startled on May 20, 1883, by booming sounds which came from Krakatoa, one hundred miles distant. A mail steamer pa.s.sing through the strait, had her compa.s.s violently agitated. Next day a sprinkling of ashes was noticed at some places on each side of the strait, and toward evening a steam-column rising from Krakatoa revealed the locality of the disturbance. The commander of the German war ship Elisabeth, while pa.s.sing, estimated the dust-column to be about thirty-six thousand feet, or seven miles high.
Volcanic phenomena being common to that region, no fears were entertained by the inhabitants in the vicinity; and an excursion party even started from Batavia to visit the scene of action. They reached the island on May 27th, and saw that the cone of Perborwatan was active, and that a column of vapor arose from it to a height of not less than ten thousand feet, while lumps of pumice were shot up to about six hundred feet. Explosions occurred at intervals of from five to ten minutes, each of these outbursts uncovering the liquid lava in the vent, the glow of which lighted up the overhanging steam-cloud for a few seconds.
Shortly after this visit the activity diminished. But on June 19th it was noticed at Anjer that the height of the dust and vapor-column, and likewise the explosions were again increasing. On the 24th a second column was seen rising. At length, Captain Ferzenaar, chief of the Topographical Survey of Bantam, visited Krakatoa island on August 11th. He found its forests destroyed, and the mantle of dust near the sh.o.r.es was twenty inches thick. Three large vapor-columns were noted, one marking the position of the crater of Perborwatan, while the other two were in the center of the island, and of the latter, one was probably Danan. There were also no less than eleven other eruptive foci, from which issued smaller steam-columns and dust. This was the last report prior to the great paroxysm.
During the next two or three weeks there was a decline in the energy of the volcano, but on the afternoon of Sunday, August 26th, and all through the following night, it was evident that the period of moderate eruptive action had pa.s.sed, and that Krakatoa had now entered upon the paroxysmal stage. From sunset on Sunday till midnight the tremendous detonations followed each other so quickly that a continuous roar may be said to have issued from the island. The full terrors of the eruption were now approaching. The distance of ninety-six miles from Krakatoa was not sufficient to permit sleep to the inhabitants of Batavia. All night volcanic thunders sounded like the discharges of artillery at their very doors. On the next morning there were four mighty explosions. The third was of appalling violence, and it gave rise to the most far-reaching effects. The entire series of grand phenomena at that spot extended over a little more than thirty-six hours.
Captain Thompson, of the Media, then seventy-six miles northeast of Krakatoa, saw a black ma.s.s like smoke rising into the clouds to an alt.i.tude estimated at not less than seventeen miles. The eruption was also viewed by Captain Wooldridge at a distance of forty miles. He speaks of the vapory ma.s.s looking like "an immense wall, with bursts of forked lightning, at times like large serpents rushing through the air." After sunset this dark wall resembled "a blood-red curtain with the edges of all shades of yellow, the whole of a murky tinge, with fierce flashes of lightning." Two other masters of vessels, at about the same distance from the volcano, report seeing the mastheads and yardarms of their ships aglow with electric fire. Such effects seem to be easily explicable. When we consider how enormous must be the friction going on in the hot air, through the clash against each other of myriads of particles of volcanic dust, during ejection and in their descent, it is evident that such friction is adequate to produce a widespread electrical disturbance in the surrounding atmosphere. The rush of steam through craters or other fissures would also contribute to these disturbances.
From these causes the compa.s.ses of pa.s.sing ships were much disturbed.
And yet the fall of magnetic oxide of iron (magnet.i.te), a const.i.tuent of volcanic ash, possibly had some share in creating these perturbations. On the telephone line from Ish.o.r.e, which included a submarine cable about a mile long, reports like pistol shots were heard. At Singapore, five hundred miles from Krakatoa, it was noted at the Oriental Telephone Company"s station that, on putting the receiver to the ear, a roar like that of a waterfall was heard. So great was the ma.s.s of vapor and dust in the air, that profound darkness, which lasted many hours, extended even to one hundred and fifty miles from the focus of the eruption. There is the record, among others, that it was "pitch dark" at Anjer at two o"clock in the afternoon of the 26th.
So great, too, was the ejective force that the fine volcanic dust was blown up to a height of fifty thousand feet, or over nine miles, into s.p.a.ce. Another estimate gives the enormous alt.i.tude of seventeen miles to which the dust had been blown. The volcanic ash, which fell upon the neighboring islands within a circle of nine and one half miles radius, was from sixty-five to one hundred and thirty feet thick. At the back of the island the thickness of the ash beds was from one hundred and ninety-five to two hundred and sixty feet. Ma.s.ses of floating pumice enc.u.mbered the strait. The coa.r.s.er particles of this ash fell over a known area equal to 285,170 square miles, a s.p.a.ce equal to the whole of the New England States, New York, New Jersey, Pennsylvania, Ohio, Indiana and Illinois. It is calculated that the matter so ejected must have been considerably over a cubic mile in volume.
Another distinguishing feature of this display of nature"s powers was the magnitude and range of the explosive sounds. Lloyd"s agent at Batavia, ninety-four miles distant from Krakatoa, reported that on the morning of the 27th the reports and concussions were simply deafening.
At Carimon, Java, which is three hundred and fifty-five miles distant, the natives heard reports which led them to suppose that a distant ship was in distress; boats put off for what proved to be a futile search. The explosions were heard not only all over the province of Maca.s.sar, nine hundred and sixty-nine miles from the scene of the eruption, but over a yet wider area. At a spot one thousand one hundred and sixteen miles distant--St. Lucia bay, Borneo--some natives heard the awful sound. It stirred their consciences, for, being guilty of murder, they fled, fearing that such sounds signified the approach of an avenging force. Again, in the island of Timor, one thousand three hundred and fifty-one miles away, the people were so alarmed that the government sent off a steamer to seek the cause of the disturbance.
At that time, also, the shepherds on the Victoria plains, West Australia, thought they heard the firing of heavy artillery, at a spot one thousand seven hundred miles distant. At midnight, August 26th, the people of Daly Waters, South Australia, were aroused by what they thought was the blasting of a rock, a sound which lasted a few minutes. "The time and other circ.u.mstances show that here again was Krakatoa heard, this time at the enormous distance of two thousand and twenty-three miles." And yet there is trustworthy evidence that the sounds were heard over even greater distances. Thundering noises were heard at Diego Garcia, in the Chagos islands, two thousand two hundred and sixty-seven miles from Krakatoa. It was imagined that some vessel must be in distress, and search was accordingly made. But most remarkable of all, Mr. James Wallis, chief of police in Rodriguez, across the Indian ocean, and nearly three thousand miles away from Krakatoa, made a statement in which he said that "several times during the night of August 26th-27th reports were heard coming from the eastward like the distant roar of heavy guns. These reports continued at intervals of between three and four hours." Obviously, some time was needed for the sounds to make such a journey. On the basis of the known rate of velocity, they must have been heard at Rodriguez four hours after they started from their source.
And yet, great as was the range of such vibrations, they could not be compared with that of the air-wave caused by the mighty outburst. This atmospheric wave started from Krakatoa at two minutes past ten on that eventful Monday morning, moving onward in an ever-widening circle, like that produced when a stone is thrown into smooth water. This ring-like wave traveled on at the rate of from six hundred and seventy-four to seven hundred and twenty-six miles an hour, and went around the world four, if not even seven times, as evidenced by the following facts: Batavia is nearly a hundred miles from the eruptive focus under review. There was connected with its gas-holder the usual pressure recorder. About thirteen minutes after the great outburst, this gauge showed a barometric disturbance equal to about four-tenths of an inch of mercury, that is, an extra air pressure of about a fifth of a pound on every square inch. The effects on the air of minor paroxysmal outbreaks are also recorded by this instrument; but barometers in the most distant places record the same disturbance. The great wave pa.s.sed and repa.s.sed over the globe and no inhabitant was conscious of the fact. Barometers in the princ.i.p.al cities of the world automatically recorded this effect of the first great wave from Krakatoa to its antipodes in Central America, and also the return wave. The first four oscillations left their mark on upward of forty barograms, the fifth and sixth on several, and at Kew, England, the existence of a seventh was certainly established.
At the same time that this immense aerial undulation started on its tour around the world, another wave but of awful destructiveness, a seismic sea-wave, started on a similar journey. There can hardly be a doubt that this so-called "tidal-wave" was synchronous with the greatest of the explosions. A wave from fifty to seventy-two feet high arose and swept with resistless fury upon the sh.o.r.es each side of the straits. The destruction to life and property will probably never be fully known. At least thirty-six thousand lives were lost; a great part of the district of North Bantam was destroyed; and the towns of Anjer, Merak, Tyringin, and neighboring villages were overwhelmed. A man-of-war, the Berouw, was cast upon the sh.o.r.e of Sumatra nearly two miles inland, and ma.s.ses of coral from twenty to fifty tons in weight were torn from the bed of the sea and swept upon the sh.o.r.e.
The formerly fertile and densely populated islands of Sibuku and Sibesi were entirely covered by a deposit of dry mud several yards thick, and furrowed by deep creva.s.ses. Of the inhabitants all perished to a man. Three islands, Steers, Calmeyer, and the islet east of Verlaten, completely disappeared and were covered by twelve or fourteen feet of water. Verlaten, formerly one ma.s.s of verdure, was uniformly covered with a layer of ashes about one hundred feet thick.
A few days after this eruption some remarkable sky effects were observed in different parts of the world. Many of these effects were of extraordinary beauty. Accordingly scientific inquiry was made, and in due time there was collected and tabulated a list of places from whence these effects were seen, together with the dates of such occurrences. Eventually it was concluded that such optical phenomena had a common cause, and that it must be the dust of ultra-microscopic fineness at an enormous alt.i.tude. All the facts indicated that such a cloud started from the Sunda straits, and that the prodigious force of the Krakatoa eruption could at that time alone account for the presence of impalpable matter at such a height in the atmosphere.
This cloud traveled at about double the speed of an express train, by way of the tropics of Cancer and of Capricorn. Carried by westerly-going winds, in three days it had crossed the Indian Ocean and was rapidly moving over Central Africa; two days later it was flying over the Atlantic; then, for two more days over Brazil, and then across the Pacific toward its birth-place. But the wind still carried this haze of fine particles onward, and again it went around the world within a fortnight. In November, the dust area had expanded so as to include North America and Europe.
Here are a few facts culled from the report of the Royal Society of London. On the 28th, at Seych.e.l.les, the sun was seen as through a fog at sunset, and there was a lurid glare all over the sky. At the island of Rodriguez, on that day, "a strange, red, threatening sky was seen at sunset." At Mauritius (28th), there is the record "Crimson dawn, sun red after rising, gorgeous sunset, first of the afterglows; sky and clouds yellow and red up to the zenith." 28th and 29th, Natal--"most vivid sunsets, also August 31st and September 5th, sky vivid red, fading into green and purple." On the last days of August and September 1st, the sun, as seen from South America, appeared blue, while at Panama on the 2nd and 3d of that month, the sun appeared green. "On the 2nd of September, Trinidad, Port of Spain--Sun looked like a blue ball, and after sunset the sky became so red that there was supposed to be a big fire." "On the 5th of September, Honolulu--Sun set green. Remarkable afterglow first seen. Secondary glow lasted till 7:45 P. M., gold, green and crimson colors. Corona constantly seen from September 5th to December 15th. Misty rippled surface of haze."
It remains to be said that when this now famous island of Krakatoa was visited shortly after the great eruption, wonderful changes were noted. The whole northern and lower portion of the island had vanished, except an isolated pitchstone rock, ten yards square, and projecting out of the ocean with deep water all around it. What a tremendous work of evisceration this must have been is attested by the fact that where Krakatoa island, girt with luxuriant forests, once towered from three hundred to fourteen hundred feet above the sunlit waters, it is now, in some places, more than a thousand feet below them.
There is no region more frequently visited by earthquakes than the beautiful lands in the Indian ocean, and nowhere has greater damage been done than on the beautiful island of Java. In former ages Sumatra and Java formed one single island, but in the year 1115, after a terrific earthquake, the isthmus which connected them, disappeared in the waves with all its forests and fertile fields.
These two islands have more than 200 volcanoes, half of which have never been explored, but it is known that whenever there has been an eruption of any one of them, one or the other of the two islands has been visited by an earthquake. Moreover, earthquakes are so frequent in the whole archipelago that the princ.i.p.al ones serve as dates to mark time or to refer to, just as in our own country is the case with any great historic event. A month rarely pa.s.ses without the soil being shaken, and the disappearance of a village is of frequent occurrence.
In 1822 the earthquake which accompanied the eruption of the Javanese volcano of Yalung-Yung, utterly destroyed 144 towns and villages. In 1772, when the Papand-Yung was in a state of furious eruption, the island of Java was violently agitated, and a tract of nearly twenty-five square leagues, which but the day before had been covered with flourishing villages and farms, was reduced to a heap of ruins.
In 1815 an earthquake, accompanied by an eruption of the volcano of Timboro, in the island of Sumatra, destroyed more than 20,000 lives.
It is rare even in this archipelago that there occurs a cataclysm so terrible as that of 1883. When the first eruption of Krakatoa occurred on August 25, it seemed that it was a signal to the other volcanoes of Java and Sumatra. By midday Maha-Meru, the greatest, if not the most active of the Javanese volcanoes, was belching forth flame continuously. The eruption soon extended to the Gunung-Guntus and other volcanoes, until a third of the forty-five craters in Java were either in full blast, or beginning to show signs of eruption. While these eruptions were going on, the sea was in a state of tremendous agitation. The clouds floating above the water were charged with electricity, and at one moment there were fifteen large water-spouts to be seen at the same time.
Men, women and children fled in terror from their crumbling habitations, and filled the air with their cries of distress. Hundreds of them who had not time to escape were buried beneath the ruins. On Sunday evening the violence of the shocks and of the volcanic eruptions increased, and the island of Java seemed likely to be entirely submerged. Enormous waves dashed against the sh.o.r.e, and in some cases forced their way inland, while enormous crevices opened in the ground, threatening to engulf at one fell swoop all the inhabitants and their houses.
