West Coast surfers might snicker at the cause, but the National Weather Service confirms the rare 4-foot (1.2 meter) wave was caused by a kind of tsunami, just not the kind you usually hear about.
The term "tsunami" is a borrowing from the Japanese tsunami 津波, meaning "harbour wave."For the plural, one can either follow ordinary English practice and add an s, or use an invariable plural as in the Japanese. [14]
A tsunami and seiche in Lake Tahoe can be treated as shallow-water long waves as the maximum water depth is much smaller than the wavelength. This demonstrates the impact that lakes have on tsunami wave characteristics, which is different from ocean tsunami wave characteristics because the ocean is deeper, and lakes are relatively shallow in ...
Only about 3% of historical tsunami events (from 2000 BC through 2014) are known to have meteorological origins, although their true prevalence may be considerably higher than this because 10% of historical tsunamis have unknown origins, tsunami events in the past are often difficult to validate, and meteotsunamis may have previously been ...
Last week, when a line of thunderstorms moved across Clearwater Beach, Florida, located just west of Tampa, it unleashed gusty winds, torrential rain and another unique weather phenomenon that ...
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.

A megatsunami is a tsunami with an initial wave amplitude measured in many tens or hundreds of metres.The term "megatsunami" has been defined by media and has no precise definition, although it is commonly taken to refer to tsunamis over 100 metres (330 ft) high. [2]
Tsunami in Japan An earthquake and later a tsunami hit the country’s main island of Honshu on March 11, 2011. After this disaster, the nuclear power plant in Fukushima, Japan releases significant levels of radiation due to damage from the earthquake.
