A 3.4 magnitude earthquake struck just east of Golfito at 8:07 p.m. Thursday, according to the Laboratorio de Ingeniería Sísmica at the Universidad de Costa Rica.
The epicenter was fixed at 3.8 kilometers (about 2.3 miles) south of Río Claro and 11.3 kilometers (about 7 miles) east of Golfito. The location is just south of the Interamericana highway. Only an automatic sensing station at Golfito registered the quake, said the laboratory.
The location is near the estimated epicenters of two other recent quakes.
