A volcanic tsunami, also called a volcanogenic tsunami, is a tsunami produced by volcanic phenomena. About 20–25% of all fatalities at volcanoes during the past 250 years have been caused by volcanic tsunamis. The most devastating volcanic tsunami in recorded history was that produced by the 1883 eruption of Krakatoa. The waves reached ...
Tsunamis are most frequently caused by earthquakes, while those caused by volcanic eruptions are rare. [84] [85] Fewer than 100 volcanic tsunamis were recorded in the prior two centuries. [84] According to an official at GNS Science, the suspected cause of the tsunami was an undersea eruption that destroyed part of the island on 14 January ...

Volcanic eruption can damage originally stable magma chambers, causing a portion of the volcano to collapse. [1] While eruption is one cause, sector collapse can occur without any eruption. Magmatic intrusions can also lead to sector collapse. Dikes fracture and deform rock, leaving the volcano weaker and more susceptible to collapse.
