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.
The 2004 Indian Ocean tsunami was a teletsunami.. A teletsunami (also called an ocean-wide tsunami, distant tsunami, distant-source tsunami, far-field tsunami, or trans-ocean tsunami) is a tsunami that originates from a distant source, defined as more than 1,000 km (620 mi) away or three hours' travel from the area of interest, [1] [2] sometimes travelling across an ocean.
Smaller (M w 4.2) earthquakes in Japan can trigger tsunamis (called local and regional tsunamis) that can devastate stretches of coastline, but can do so in only a few minutes at a time. Landslides The Tauredunum event was a large tsunami on Lake Geneva in 563 CE, caused by sedimentary deposits destabilised by a landslide.
Tsunamis and meteotsunamis are otherwise similar enough that it can be difficult to distinguish one from the other, as in cases where there is a tsunami wave but there are no records of an earthquake, landslide, or volcanic eruption.
Ordinary tsunamis, even those associated with the most powerful strike-slip earthquakes, typically do not reach heights in excess of 30 m (100 ft). [ 3 ] [ 4 ] By contrast, megatsunamis are caused by landslides and other impact events that displace large volumes of water, resulting in waves that may exceed the height of an ordinary tsunami by ...
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.
A Whatcom County resident survived the deadliest tsunami in recorded history when she was just 13 years old. Now, 19 years after the disaster, she’s telling her story. Monica Connelly was ...
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 ...
