A period of tremor and vigorous ash venting followed about an hour later. Typically, for an eruption to occur, enough magma must accumulate in the chamber under the volcano. Although these pyroclastic flows are similar in behaviour and consequent hazard to the dome collapse type, they are less constrained by topography, as the explosion can eject the materials in all directions around the volcano. Britain offered temporary, and later permanent, residence to all Montserratians. Vesuvius eruption that year. What caused the eruption?
