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:
“Each of us, even the lowliest and most insignificant among us, was uprooted from his innermost existence by the almost constant volcanic upheavals visited upon our European soil and, as one of countless human beings, I can’t claim any special place for myself except that, as an Austrian, a Jew, writer, humanist and pacifist, I have always been precisely in those places where the effects of the thrusts were most violent.”
—Stefan Zweig (18811942)
“We cannot be any stronger in our foreign policy—for all the bombs and guns we may heap up in our arsenals—than we are in the spirit which rules inside the country. Foreign policy, like a river, cannot rise above its source.”
—Adlai Stevenson (1900–1965)
