Introduction to volcano characteristics and activity
... This image shows a pyroclastic flow from the Mt Mayon volcano in the Phillipines. These are superheated (and fast travelling) clouds of pyroclastic material, formed by collapse of the volcanic column or collapse of accumulated viscous lava. They are deadly and few have survived a direct hit by one. ...

Lithosphere L > E Heat flowing in Earth`s core below the lithosphere
... During volcanic eruptions magma releases its dissolved gases into the atmosphere. Gases are also released from “old” magma that either remains below ground (for example, as an intrusion) or is rising toward the surface. In this case, gases may escape continuously into the atmosphere from the soil, v ...
