explosive eruption
Sudden forceful discharge
An explosive eruption is a volcanic event in which magma, gas, and rock fragments are violently ejected into the atmosphere.
Unlike effusive eruptions where lava flows gradually, explosive eruptions produce dramatic ash columns, pyroclastic flows, and widespread debris.
The explosiveness depends on magma viscosity and gas content: Mount St. Helens produced one of the most devastating explosive eruptions in U.S. history.
