The word tsunami comes from the Japanese for "harbor wave." They are especially dangerous in harbors where the water can become trapped and compressed, causing higher waves.
A tsunami (/(t) s u ː ˈ n ɑː m i, (t) s ʊ ˈ ... Major areas of current research include determining why some large earthquakes do not generate tsunamis while ...
The segments have different types of rock and varying seismic characteristics — meaning some could be more dangerous than others. Earthquake and tsunami modelers are beginning to assess how the ...
While earthquakes as large as 6.5 or below are very unlikely to trigger a tsunami and those between 6.5 and 7.5 do not usually produce destructive tsunamis, larger earthquakes could result in much ...
A tsunami earthquake can be defined as an undersea earthquake for which the surface-wave magnitude M s differs markedly from the moment magnitude M w, because the former is calculated from surface waves with a period of about 20 seconds, whereas the latter is a measure of the total energy release at all frequencies.

Both surface deformation and faulting and shaking-related geological effects (e.g., soil liquefaction, landslides) not only leave permanent imprints in the environment, but also dramatically affect human structures. Moreover, underwater fault ruptures and seismically triggered landslides can generate tsunami waves.
A tsunami that devastated the area around Indonesia's Sunda Strait, leaving at least 222 dead and hundreds more injured, struck fast and without warning on Saturday. While most tsunamis have ...
This is the third largest earthquake in recorded history and generated massive tsunamis, which caused widespread devastation when they hit land, leaving an estimated 230,000 people dead in countries around the Bay of Bengal and the Indian Ocean. May 4, 1998 A part of the island of Yonaguni was destroyed by a submarine earthquake. May 22, 1960
