The national emergency commission said that a Friday afternoon earthquake caused little damage except the falling of some objects.
The quake was in the Pacific west of Parque Nacional Manuel Antonio and took place at 1:24 p.m. A.M. Costa Rica reported the event a short time later in an update.
The Red Sismológica Nacional estimated the magnitude at 5.1. The Laboratorio de Ingeniería Sísmica said 5.0. Both are at the Universidad de Costa Rica.
The Observatorio Vulcanológico y Sismológico at Universidad Nacional in Heredia said 5.3.
The differences are a result of the various methods the agencies have of keeping track of quakes and the location of their sensors.
The national emergency said the local Comité Municipal de Emergencia de Parrita conducted an evaluation of buildings there to make sure there was no damage.
The Caja Costarricense de Seguros Social evacuated its facilities when the tremor was felt. That is standard procedure.
Normal operations resumed as soon as officials determined that there was not damage to structures.
