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).
The 1992 Nicaragua earthquake occurred off the coast of Nicaragua at 6:16 p.m. on September 2. Some damage was also reported in Costa Rica. At least 116 people were killed and several more were injured. The earthquake was caused by movement on a convergent plate boundary. It created a tsunami disproportionately large for its surface wave magnitude.
