The great sea wave rushed from Krakatoa to the Mauritius in eight hours. It rolled around the coasts of the Australian continent, dashing into the southern harbors, sweeping through the narrow Bass Straits. It rose and fell upon Hawaiian coasts in a perplexing manner. It surged against South America; against East Africa; it rounded Cape Horn and made itself known on the coasts of France, upon our Atlantic shore. It encircled the world—the greatest sea wave ever known.
The volcanic, microscopic dust remained long in the air, and occasioned the singular redness of the sky at morn and eve that prevailed throughout the world for the next two years. Apart from this suspended dust, the volcano threw out as much matter as the Mississippi bears to the gulf in two hundred and fifty years.
The atmospheric wave of low barometer was even more marked than the oceanic wave. On the day when Krakatoa sank into the sea, the barometric oscillation was noticed all over the world. From the time at which it reached Berlin, it is found to have travelled eight hundred and seventy-five miles an hour. Thirty-six hours later the barometric oscillations were repeated, but less pronounced. Thirty-seven hours afterward there came a third, and still fainter series. It appears, then, that the atmospheric wave, set in motion by this stupendous outbreak, was powerful enough to thrice encircle the world.
It has been but a short time since geologists believed the magnitude of the subterranean forces to be greatly decreased; but in view of a century of great eruptions closed by such an appalling convulsion, it must be said that the fiery forces are at least as active and powerful as ever.
CHAPTER XXIII.
EARTHQUAKES.
“Diseased Nature oftentimes breaks forth
In strange eruptions: and the teeming earth
Is with a kind of colic pinched and vexed
By the imprisoning of unruly wind
Within her womb; which for enlargement striving,
Shakes the old beldam earth, and topples down
Steeples and moss-grown towers.”
UCH is the theory of earthquakes as laid down by “Wild Will Shakespeare.” Whether it be an expression of the popular belief of the day, or a personal opinion, is not easy to determine. If the latter, he had, as we shall see by and by, many predecessors in the same belief. His metaphor, though more elegantly expressed, cannot compare with the Indian’s for terseness and force: “Ground heap sick—heap belly ache—no good!”
We have already seen that the forces producing earthquakes and volcanic action are conceded to be practically identical. The latter seldom occurs without the former; but the former are frequent in districts far removed from any known vent of subterranean heat. So the expression of Shakespeare is not so far wrong as might be, so far as our present knowledge goes.
In the Hindoo cosmogony successive ages of the world are separated by periods of chaos; and no wilder image of unreined destruction has fancy ever dreamed. The earth is to be eternal. There is one eternal, invisible spirit, Brahm, from whom springs Brahma, who creates a race of gods. These frame the earth into orderly condition, and rule it for four hundred thousand years. At the end of that time, the land and sea and sky meet in gigantic ruin; the gods are no more, save only Vishnu, the preserver. The sea covers all things and eternal night is accompanied by eternal tempest.
