Volcanic Bombs
Volcanic bombs are extrusive igneous rocks that range from the size of a book to small automobile, that are explosively ejected from stratovolcanoes during their peak eruptive phases. These bombs can travel over fifteen miles (20 km) away from the volcano and present a risk to buildings and people while traveling at very high speeds (hundreds of miles per hour or km/h) through the air. The bombs do not themselves explode on impact, but rather carry enough force so as to have destructive effects as if they exploded.

Famous quotes containing the words volcanic and/or bombs:
“Pity the planet, all joy gone
from this sweet volcanic cone;”
—Robert Lowell (1917–1977)
“Today the discredit of words is very great. Most of the time the media transmit lies. In the face of an intolerable world, words appear to change very little. State power has become congenitally deaf, which is why—but the editorialists forget it—terrorists are reduced to bombs and hijacking.”
—John Berger (b. 1926)
