[PDF] Eruption

Overview

volcanic eruption, an eruption of molten rock, hot rock fragments, and hot gases through a volcano, which is a vent in a planet’s or satellite’s crust. Volcanic eruptions can cause disastrous loss of life and property. They range from relatively gentle eruptions, as typically seen in Hawaiian volcanoes, to massively destructive ones, such as the er...

How volcanoes erupt

Volcanic eruptions occur as a result of heat moving under Earth’s surface. They often begin with an accumulation of gas-rich magma (molten underground rock) in reservoirs near Earth’s surface, though they may be preceded by emissions of steam and gas from small vents in the ground. Small earthquakes, which may be caused by a rising plug of dense, viscous magma oscillating against a sheath of more permeable magma, may also signal volcanic eruptions, especially explosive ones.
