Trapped gas builds immense pressure, eventually shattering magma into fragments called tephra. This can create pyroclastic flows —fast-moving clouds of hot ash and gas that destroy everything in their path.

Volcanic activity is primarily driven by the movement of tectonic plates. Most eruptions occur at , where magma forms through decompression melting or the addition of water in subduction zones. There are three main mechanisms that trigger an eruption: Gas release under decompression: Causes magmatic eruptions. Most eruptions occur at , where magma forms
Driven by ground or surface water heating up, causing phreatic eruptions. Eruption Styles and Hazards
