On March 27, 1868, a series of earthquakes began and became more startling from day to day, until their succession became so rapid that the island quivered like the lid of a boiling pot nearly all the time between the heavier shocks. The trembling was like that of a ship struck by a heavy wave. Late in the afternoon of April 2, the climax came. The crust of the earth rose and sank like the sea in a storm. Rocks were rent, mountains fell, buildings and their contents were shattered, trees swayed like reeds, animals ran about demented; men thought the judgment had come. The earth opened in thousands of places, the roads in Hilo cracked open; horses and their riders, and people afoot, were thrown violently to the ground. At Kilauea the shocks were as frequent as the ticking of a watch. In Kau, south of Hilo, 300 shocks were counted during the day. An avalanche of red earth, supposed to be lava, burst from the mountain side, throwing rocks high into the air, swallowing up houses, trees, men and animals, and traveling three miles in as many minutes, burying a hamlet with thirty-one inhabitants, and 500 head of cattle.
The people of the valleys fled to the mountains, which themselves were splitting in all directions, and collecting on an elevated spot, with the earth reeling under them, they spent a night of terror. Looking toward the shore, they saw it sink, and at the same moment a wave, whose height was estimated at from forty to sixty feet, hurled itself upon the coast and receded five times, destroying whole villages and engulfing forever forty-six people who had lingered too near the shore.
Still the earthquakes continued, and still the volcanoes gave no sign. People put their ears to the quivering ground and heard, or thought they heard, the surgings of the imprisoned lava sea rending its way among the ribs of the earth. Five days after the destructive earthquake of April 2, the ground south of Hilo burst open with a crash and a roar, which at once answered all questions concerning the volcano. The molten river, after traveling underground for twenty miles, emerged through a fissure two miles in length with a tremendous force and volume. Four huge fountains boiled up with terrific fury, throwing crimson lava and rocks weighing many tons from 500 to 1,000 feet.
Mr. Whitney, of Honolulu, who was near the spot, says: “From these great fountains to the sea flowed a rapid stream of red lava, rolling, rushing, and tumbling like a swollen river, bearing along in its current large rocks that made the lava foam as it dashed down the precipice and through the valley into the sea, surging and roaring throughout its length like a cataract, with a power and fury perfectly indescribable. It was nothing else than a river of fire from 200 to 800 feet wide and twenty deep, with a speed varying from ten to twenty-five miles an hour. From the scene of these fire fountains, whose united length was about one mile, the river in its rush to the sea divided itself into four streams, between which it shut up men and beasts. Where it entered the sea it extended the coast-line half a mile, but this worthless accession to Hawaiian acreage was dearly purchased by the loss, for ages at least, of 4,000 acres of valuable agricultural land, and a much larger quantity of magnificent forest.”
The entire southeast shore of Hawaii sank from four to six feet, which involved the destruction of several hamlets and the beautiful fringe of cocoanut trees. Though the region was very thinly peopled, 100 lives were sacrificed in this week of horrors; and from the reeling mountains, the uplifted ocean, and the fiery inundation, the terrified survivors fled into Hilo, each with a tale of woe and loss. The number of shocks of earthquake counted was 2,000 in two weeks, an average of 140 a day; but on the other side of the island the number was incalculable.
Since that time there have been several eruptions of these great Hawaiian volcanoes, but none so destructive to life and property. Only two years ago the crater of Mauna Loa was in eruption for some weeks, and travelers journeyed to the vicinity from all over the world to see the grand display of Nature’s power in the fountains of lava and the blazing rivers flowing down the mountain side. The spectacle could be viewed perfectly at night from ships at sea, and from places of safety on shore.
Across the North Pacific, from Kamschatka to Alaska, is a continuous chain of craters in the Aleutian islands, forming almost a bridge over the ocean, and from Alaska down the western coasts of the two Americas is a string of the mightiest volcanoes in existence. Iceland is a seething caldron under its eternal snows, and in a hundred places where some great, jagged cone of a volcano rises, seemingly dead and lifeless, only a fire-brand in the hand of nature may be needed to awaken it to a fury like that of which its vast lava beds, pinnacles, and craters are so eloquent.
The world’s record for the extent of an eruption probably belongs to the great volcano Skaptan Jokul, in Iceland. This eruption began on June 11, 1783, having been preceded by violent earthquakes. A torrent of lava welled up into the crater, overflowed it, and ran down the sides of the cone into the channel of the Skapta river, completely drying it up. The river had occupied a rocky gorge, from 400 to 600 feet deep, and averaging 200 feet wide. This gorge was filled, a deep lake was filled, and the rock, still at white heat, flowed on into subterranean caverns. Tremendous explosions followed, throwing boulders to enormous heights. A week after the first eruption another stream of lava followed the first, debouched over a precipice into the channel of another river, and finally, at the end of two years, the lava had spread over the plains below in great lakes twelve to fifteen miles wide and a hundred feet deep. Twenty villages were destroyed by fire, and out of 50,000 inhabitants nearly 9,000 perished, either from fire or from noxious vapors.
The Skapta river branch of this lava stream was fifty miles long and in places twelve to fifteen miles wide; the other stream was forty miles long, seven miles broad, and the range of depth in each stream was from 100 to 600 feet. Professor Bischoff has called this, in quantity, the greatest eruption of the world, the lava, piled, having been estimated as of greater volume than is Mont Blanc.
Regarding the volcanoes of the United States, Mount Shasta is one of the most interesting of them. It has an altitude of 14,350 feet, towering more than a mile above its nearest neighbor. Four thousand feet of its peak are above timber line, covered with glaciers, while the mountain’s base is seventeen miles in diameter. Shasta is almost continually showing slight evidences of its internal fires. Another of the famous cones is that of Mount Hood, standing 11,225 feet, snow-capped, and regarded as an extinct volcano.
