A 1991 earthquake in Limón produced only small waves on the Caribbean coast. Description of the Earthquake At 1558 h on 22 April 1991, an earthquake measuring 7.4 (Richter scale) struck in the Limon Province of Costa Rica, on the eastern Caribbean coast. This massive earthquake caused the destruction of many buildings, roads, and even coral reefs. In the aftermath of large earthquakes in South America, small tsunami waves did manage to hit Costa Rican shores. Seismicity, faulting and crustal deformation are not consistent with erlier interpretations of an east-northeast oriented strike-slip tectonic boundary in the area. On April 22nd, 1991, an earthquake with magnitude Mw 7.6 ruptured along the thrust faults that form the North Panamá Deformed Belt (NPDB). 18.1 ).

Largest earthquake ever recorded in Costa Rica This 7.7 Mw earthquake actual had its epicenter in Costa Rica, but a majority of the fatalities occurred in Panama. In fact, we can say that Limon's northern plain, down to 32 ft, was submerged during the Flandrian marine transgression 6500 years ago, and has since emerged with the help of positive neotectonics, as demonstrated by the 1991 Limon earthquake that raised the land 3-5 ft in some places (Figure 7.27). The activity culminated with the event of interest to this work: the Limon-Telire earthquake. The quake occurred on 22 April, 1991, at 15:57 local time (21:57 UTC). The moment magnitude 7.5 earthquake occurred approximately 40 km south-southwest of Limon, and resulted in a coseismic uplift of up to 1.5 meters along Costa Rica's east coast. The second largest recorded tsunami along the Caribbean margin of Central America occurred 25 years ago. Fetching list of earthquakes.
