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 ...
A tsunami hitting a coastline. This article lists notable tsunamis, which are sorted by the date and location that they occurred.. Because of seismic and volcanic activity associated with tectonic plate boundaries along the Pacific Ring of Fire, tsunamis occur most frequently in the Pacific Ocean, [1] but are a worldwide natural phenomenon.
Films about tsunamis, a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake. Earthquakes, volcanic eruptions and other underwater explosions (including detonations, landslides, glacier calvings, meteorite impacts and other disturbances) above or below water all have the potential to generate a tsunami.
1741 eruption of Oshima–Ōshima and the Kampo tsunami; 1871 Ruang eruption and tsunami; 1979 Lembata tsunami; 2002 Stromboli tsunami; 2018 Sunda Strait tsunami; 2022 Hunga Tonga–Hunga Haʻapai eruption and tsunami
Based on examining historical observations of the eruption, Pranantyo and others interpreted it as the partial collapse of the eastern volcanic flank. Simulation of a flank collapse and the triggered tsunami indicate the volume of the slide at 0.1 km 3 (0.024 cu mi) best fit the historical descriptions of the tsunami heights on nearby islands. [1]
On August 29 at 05:00, a second and more violent eruption took place on the island and was followed–up by a large tsunami up to 90 m (300 ft). [3] [4] The tsunami engulfed many coastal villages and towns along the shores of the Sea of Japan. While the eruption itself did not result in any casualties, the ensuing tsunami drowned over 2,000 people.
The 1792 Unzen landslide and tsunami resulted from the volcanic activities of Mount Unzen (in the Shimabara Peninsula of Nagasaki Prefecture, Japan) on 21 May. This caused the collapse of the southern flank of the Mayuyama dome in front of Mount Unzen, resulting in a tremendous tsunami , killing 15,000 people altogether. [ 2 ]
The Ancient Greek historian Thucydides suggested in his 5th century BC History of the Peloponnesian War that tsunamis were related to submarine earthquakes, [12] [13] but the understanding of tsunamis remained slim until the 20th century, and much remains unknown. Major areas of current research include determining why some large earthquakes do ...
