I had the remarkable experience of being rowed in a skiff over the submerged tongue of an eastern flow, trailing a thermometer in the increasingly boiling water. When the steaming water about us reached scalding temperature, we had the unpleasant thought that if we should capsize we would be cooked. We found boiled horses and cattle along the beaches, and thousands of dead fish. A climb near the eastern flank vent showed a portion of the moving lava flow pouring down the slope into a glowing cavern under a shell of its own bouldery texture. The thousands of dollars of relief which came to Japan from America and elsewhere were handled with scrupulous honesty, and the inhabitants of the island were rehabilitated on Tanegashima, another island of the Ryukyu Archipelago. Scientific investigations showed by leveling that the mountain had been lifted a few feet by the internal penetration of the lava, and reexamination of the benchmarks along roads extending out radially indicated that the north end of the bay bottom and shore had definitely sunk, as though underground lava had been withdrawn from that region, to push up, swell, and overflow the mountain. This effect of subsidence outside was traced and shown to gradually lessen for a hundred miles from the place of greatest sinking. Investigation carried out by the geologist colleagues of Omori culminated in a monumental publication which demonstrates the solidarity of the Japanese methods of science. And both Omori and Professor Koto published books on Sakurajima in English, with maps, photographs, curves, and seismograms. Omori, in 1910, had anticipated movement of the earth about a volcanic center as swelling up one place and sinking down in another while eruption was going on. At that time, he described Usu Volcano at the opposite end of Japan, where leveling instruments showed graded changes in height made by the Usu eruption. A remarkable physiographic character of Usu Mountain, and of the adjacent basin of Lake Toya, is that basin and dome appear complementary, just as Kagoshima Bay was compensated by Sakurajima. This same pairing of lake with volcano has been noted in other parts of Japan, as though tumefaction by lava penetration and lava eruption had robbed the underpinning of an adjacent piece of ground, which lowered and became a lake by filling up with groundwater.
