Significant volcanic eruptions in Comoros in the last 200 years

The following list shows all volcanic eruptions of the last 200 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 eruption 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 meters up to 1 kilometer high. From VEI 8, a volcano is considered a super volcano. Here, more than 1,000 cubic kilometers of tephra are thrown to altitudes of more than 25 kilometers.

The highest explosivity index in Comoros reached in the review period was VEI 2 in 1991. The volcano Karthala threw tephramasses of at least 1 million cubic metres over 1 kilometre high. Such small volcanic eruptions can theoretically occur several times a year.
