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.
