Bombs and blocks

This film clip, taken during the 1954 eruption of Ngāuruhoe, shows incandescent material being thrown out of the crater. Material that is ejected as molten lava is called a volcanic bomb, and often shows the effect of spinning in the air or landing on the ground; cow-pat bombs were common, and their shape can be readily imagined.

Solid chunks of lava blasted from the volcano are called blocks. The huge size of some of these illustrates the power of the eruption.
