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 ...
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.
A model of the quake and subsequent tsunami shows the wave reaching the East coast about eight hours after the earthquake. Small tsunamis can also be caused by intense coastal storms, according to ...

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. [2]
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 ...
Global multihazard mortality risks and distribution (2005) for cyclones, drought, earthquakes, floods, landslides, and volcanoes (excluding heat waves, snowstorms, and other deadly hazards). A natural disaster is a sudden event that causes widespread destruction, major collateral damage, or loss of life, brought about by forces other than the ...
