What happens during an eruption?
1

Pressure builds

Magma rises and gas pressure increases inside the volcano until the crust can no longer contain it.

2

Eruption blast

Hot gas, ash, and rock fragments are explosively ejected through the crater at high speed.

3

Lava & ash clouds

Lava bombs arc through the air while ash clouds drift with the wind, cooling as they rise.
