Significant volcanic eruptions in Montserrat over the past 2000 years
The following list shows all volcanoes of the last 2000 years with significant damage. The column "VEI" stands for the volcano explosivity index, which represents the strength of the eruption from a geological point of view. This takes into account the height and volume of the rocks ejected. The scale ranges from 0-8, with the severity of the outbreak increasing tenfold with each value. For example, a VEI of 1 means that the volcano throws lava and rock masses of 100,000 to 1 million cubic metres up to 1 kilometre high. From VEI 8 a volcano is considered a super volcano. Here, more than 1000 cubic kilometers of tephra are thrown to altitudes of more than 25 kilometers.
The highest explosivity index in Montserrat was reached in the review period at VEI 3 in 2003. The volcano Soufriere Hills threw tephramasses of at least 10 million cubic meters over 3 kilometers high. Volcanoes of this size can theoretically erupt at this intensity every year.
