NOAA National Centers for Environmental Information 7 May 2024 National Geophysical Data Center Yes 9 Unknown The 1822 Costa Rica earthquake had an estimated surface-wave magnitude of 7.5–7.6 and struck the nation's Caribbean coast. The earthquake largely affected the country's east coast and generated a tsunami. Thrust faulting was inferred as a plausible mechanism for the earthquake and its damage pattern was similar to a 1991 shock of similar magnitude. Damage was also recorded in neighbouring countries. Tectonic setting At the west coast of Costa Rica, the east-moving Cocos Plate subducts beneath the Caribbean Plate which the country is situated on. Ongoing subduction occurs at the Middle America Trench where the subduction rate varies between 70 mm and 95 mm annually from Guatamela to Costa Rica. The Panama block, a microplate, lies southeast of the country; its boundary with the Caribbean Plate, the Panama Thrust Bent, is a destructive plate boundary that stretches from Colombia to Limon, near the east coast of Costa Rica. In Costa Rica, the Panama Thrust Bent causes the Caribbean Plate to underthrust beneath the Cordillera de Talamanca. A study of aftershocks following the 1991 shock suggests a near horizontal décollement at 15 km depth with steeper splays branching from the base to the surface. The northwesternmost boundary of the Panama Block is a northwest–southeast striking left-lateral fault system.Protti Marino Schwartz Susan Y.

A surface-wave magnitude of 7.5–7.6 and possibly larger was inferred from isoseismal information for the felt area of Modified Mercalli intensity VI (Strong). The isoseismal information also indicated a probable epicenter near the Caribbean coast.Tsunami Event Information https://www.ngdc.noaa.gov/hazel/view/hazards/tsunami/event-more-info/640 National Geophysical Data Center / World Data Service: NCEI/WDS Global Historical Tsunami Database. NOAA National Centers for Environmental Information 7 May 2024 10.7289/V5PN93H7 National Geophysical Data Center The Modified Mercalli intensity at the epicenter area was estimated at IX (Violent). Damage was severe in the central and western part of the country, and in eastern Panama. Coastal uplift was also reported in Panama. Damage patterns and observed uplift were similar to another earthquake in 1991; the 1822 earthquake has been suggested to have ruptured the same area of the back-arc region.Suárez Gerardo Pardo M.

Reports of a tsunami in Bocas del Toro between 1820 and 1830 may correspond to the tsunami of 7 May 1822. A historic document also described "rivers and bay grew and caused floods"; flooding and "bay grew" may be interpreted as the tsunami causing a flood.Nishenko Stuart Camacho Eduardo Astorga Allan Morales Luis D Preuss Jane Estudio de campo del tsunami de Costa Rica del 22 de abril de 1991 The 22 April 1991 Limón, Costa Rica tsunami field survey Revista Geológica de América Central 2021 65 10.15517/rgac.v0i65.47001 1 July 2025 https://www.scielo.sa.cr/scielo.php?script=sci_arttext&pid=S0256-70242021000200253 The reports of liquefaction and tsunami were also compared with the 1991 earthquake.Chacón Silvia Murillo Anthony Rivera Fabio Tsunamis históricos en el Caribe de Costa Rica Historical Tsunamis at the Costa Rican Caribbean Coast Revista Geológica de América Central 2021 65 10.15517/rgac.v0i65.46694 1 July 2025 https://www.scielo.sa.cr/scielo.php?script=sci_arttext&pid=S0256-70242021000200269 See also List of earthquakes in Costa Rica References Category:May 1822 Category:Earthquakes in Costa Rica Category:1822 earthquakes Category:1820s in Costa Rica Category:Tsunamis in Costa Rica
