In seismology, a tsunami earthquake is an earthquake which triggers a tsunami of significantly greater magnitude, as measured by shorter-period seismic waves. The term was introduced by Japanese seismologist Hiroo Kanamori in 1972. [ 1 ]
On Dec. 26, 2004, a 9.2-magnitude earthquake shook Southeast Asia, triggering the worst tsunami in recorded history. According to United Nations estimates, more than 220,000 people were killed ...

A strong earthquake rattled southern Japan on Monday, the United States Geological Survey is reporting. The notable quake registered a preliminary magnitude of 6.9, the USGS said and was recorded ...
The tsunami magnitude scale, M t, is based on a correlation by Katsuyuki Abe of earthquake seismic moment (M 0 ) with the amplitude of tsunami waves as measured by tidal gauges. [62] Originally intended for estimating the magnitude of historic earthquakes where seismic data is lacking but tidal data exist, the correlation can be reversed to ...
