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 ]
In 1964, a massive 9.2 magnitude earthquake in Alaska resulted in a tsunami in Crescent City, California five hours later. The quake's epicenter was 1,600 miles from the town.

There have been just under 40 earthquakes of magnitude 6.0 or larger in the past century within 150 miles of Thursday’s earthquake, which was the most powerful to rattle the state since a 7.1 ...
A strong 7.0 magnitude earthquake has struck off the coast of northern California, according to the US Geological Survey. A tsunami warning was initially issued along the coasts of both northern ...
A large, 7.0-magnitude earthquake struck off the coast of Humboldt County in Northern California on Thursday morning, prompting a tsunami warning for part of the North Coast. The warning was later ...
A sufficiently large earthquake magnitude and other information triggers a tsunami warning. While the subduction zones around the Pacific are seismically active, not all earthquakes generate a tsunami. Computers assist in analysing the tsunami risk of every earthquake that occurs in the Pacific Ocean and the adjoining land masses.
