The strongest and most destructive earthquake in state history was the 1931 Valentine earthquake, [3]: 20 which had an estimated magnitude of m b 5.6–6.4. [4]: 1171 The second strongest earthquake in Texas history also occurred in West Texas, registering as a magnitude 5.7 tremor near Alpine in 1995. [1]
The 2004 Indian Ocean earthquake (moment magnitude 9.1–9.3) [44] triggered a series of tsunamis on 26 December 2004 that devastated coastlines surrounding the Indian Ocean, killing an estimated 227,898 people (167,540 in Indonesia alone), making it the deadliest tsunami and one of the deadliest natural disasters in recorded history.
Earthquake environmental effects are divided into two main types: Coseismic surface faulting induced by the 1915 Fucino, Central Italy, earthquake. Primary effects: which are the surface expression of the seismogenic source (e.g., surface faulting), normally observed for crustal earthquakes above a given magnitude threshold (typically M w =5.5 ...
Small tsunamis can also be caused by intense coastal storms, according to the U.S. Tsunami Warning System. These are known as meteotsunami because they are caused not by underwater earthquakes or ...
Earthquakes which did not affect the United States directly, but caused tsunamis which did: 1960 Valdivia earthquake and tsunami – magnitude 9.5 earthquake, between 2200 and 6000 fatalities, including 61 in Hilo, HI; 2006 Kuril Islands earthquake and tsunami – magnitude 8.3 earthquake, no injuries or fatalities anywhere
Strong earthquakes can lead to damage, tsunami warnings and more. People can also be injured or killed by damage caused by a quake. Here's what to know about earthquake activity and what causes ...
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.

Earthquake insurance won’t cover the water damage from tsunamis or damage caused by a volcanic eruption associated with a tsunami. However, having an earthquake endorsement or policy could help ...
