Explanation:

This is what happens when a volcano erupts.

While active, a volcano can be a natural source of pollution. Volcanoes release ash, gas, and magma into the air and onto the ground. Earthquakes and tsunamis - Volcanoes and earthquakes share plates and because of this a volcano can set off an earthquake by creating movement in the plates. And a restless volcano endangers any nearby residents with clouds of ash, falling blocks of rock, pyroclastic flows or ash hurricanes, lava flows, and floods of debris or lahars.
