A volcano is a mountain that opens downward to a pool of molten rock below the surface of the earth.
When pressure builds up an eruptions of the volcano occurs.
Gases and rock shoot up through the opening and spill over or fill the air with lava fragments.
Eruptions can cause lateral blasts, lava flows, hot ash flows, mudslides, avalanches, falling ash and floods.
Volcano eruptions have been known to knock down entire forests.
An erupting volcano can trigger tsunamis, flash floods, earthquakes, mudflows and rockfalls.
