events
The 7.7 Mw Nicaragua earthquake affected the west coast of Nicaragua. With a Ms–Mw disparity of half a unit, this tsunami earthquake triggered a tsunami that caused most of the damage and casualties, with at least 116 killed. Typical runup heights were 3–8 meters (9.8–26.2 ft).

Seismic magnitude scales
Scales to describe earthquake strength
Seismic magnitude scales are used to describe the overall strength or "size" of an earthquake. These are distinguished from seismic intensity scales that categorize the intensity or severity of ground shaking (quaking) caused by an earthquake at a given location. Magnitudes are…Source: Wikipedia (CC BY-SA)
Tsunami earthquake
Type of earthquake which triggers a tsunami of far-larger magnitude
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. Such events are a result of relatively slow…Source: Wikipedia (CC BY-SA)
