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 last 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 ...
The tsunami caused by the 2011 Tōhoku earthquake is a prime example of the dangers of ignoring evidence of past tsunamis. It was generated by a megathrust earthquake and made tsunamis up to 40 metres (130 ft) high. It washed over sea walls and drowned over 100 designated tsunami evacuation sites. From historical records, there were three large ...
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 ...
Some volcanoes may exhibit only one characteristic type of eruption during a period of activity, while others may display an entire sequence of types all in one eruptive series. There are three main types of volcanic eruption: Magmatic eruptions are the most well-observed type of eruption.
Eruptive activity began on April 2 as a series of phreatic explosions from a fissure that opened on the north side of Mount Pinatubo. Seismographs were set up and began monitoring the volcano for earthquakes. In late May, the number of seismic events under the volcano fluctuated from day-to-day.
The 2002 Stromboli tsunami was caused by a volcanic eruption in the Aeolian Islands of Sicily, located on the Tyrrhenian Sea. In May 2002, one of the island's two active volcanoes , called Stromboli , entered a new phase of explosive activity that was initially characterized by gas and ash emission from the summit craters.

Japan dropped its highest-level tsunami alert after issuing one following a series of major earthquakes Monday but told residents of coastal areas not to return to their homes as deadly waves ...
Volcanology advances have required more than just structured observation, and the science relies upon the understanding and integration of knowledge in many fields including geology, tectonics, physics, chemistry and mathematics, with many advances only being able to occur after the advance had occurred in another field of science.
