Montserrat, an island on the edge of the Caribbean plate and South American plate, is dominated by the Soufriere Hills volcano. The volcano is moderate-sized with moderately steep slopes. Beginning in July of 1995, the volcano began erupting in a style associated with magma contacting surface water. The magma vent hardened in a rounded shape out of rock containing a mix of rhyolite and basalt,
stopping the eruption after 18 weeks. The collapse of one side of the dome sent ash and mud streaming down over the capital city and main airport, rendering them uninhabitable.

The collapse of one side of the zone created pyroclastic flows and lahar, damaging the capital city and airport.
