Quake estimated at 4.0+ took place in San Ramón

The Laboratorio de Ingenieria Sismica reported that a 4.0-magnitude earthquake took place Tuesday about 10.3 kilometers (about 6 miles) south southwest of San Isidro de Penas Blancas, San Ramón, Alajuela. The quake was felt in Ciudad Quesada and Palmares, the Laboratorio said.

The Red Sismológica Nacional estimated the magnitude at 4.2 and said the epicenter was 4.6 kilometers south of La Tigra, San Carlos, and that it was felt in La Tigra and Zarcero. The Red said the cause was a local fault.

The various earthquake monitoring agencies frequently disagree on magnitude because they use different technologies. Both agreed Tuesday on the time: 11:15 a.m.
