Eruption

Definition and stakes

Young Folks' Library, Volume XI…

“ Suppose, then, that a volcanic eruption takes place in a region of the earth's surface where successive layers of limestone, of clay, and of sandstone, have been previously deposited by the action of water. If such an eruption has force enough to break through these beds, the hot, melted masses will pour out through the rent, flow over its edges, and fill all the lesser cracks and fissures produced by such a disturbance. What will be the effect upon the stratified rocks? ”

Popular Science Monthly (1880)

“ The products thrown out in the recent eruption—which took place in 1866—like those of most other volcanic manifestations, may be divided into two categories: 1. Volatile matters exhaled in the form of gases and more or less easily condensible vapors; and, 2. Lavas overflowing in imperfect fusion, or thrown out as ashes and scoriæ. The gases varied greatly in composition during the course of the eruption. ”

Charles Morris,  The San Francisco Calamity by Earthquake and Fire

“ In the class of eruption illustrated by these examples, there is an absence of fragmental material, such as explosive volcanoes hurl into the air, and a person may stand within a few yards of a rushing stream of molten rock, or examine closely the opening from which it is being poured out, without danger or serious inconvenience. ”
