Nosara area rattled and shaken by multiple quakes

The western part of the Nicoya peninsula got multiple examples of a restless earth Wednesday night.

At 6:03 p.m. a 4.9-magnitude quake took place about four kilometers southwest of Nosara, according to the Observatorio Vulcanológico y Sismológico de Costa Rica.

A minute later a 3-magnitude quake took place just two kilometers south of Nosara, said the Observatorio. Then at 6:21 p.m. a 3.3-magnitude quake took place in the same locations, said the Observatorio

The Red Sismológica Nacional reported an additional 3.2-magnitude quake at 8:02 p.m. 18 kilometers west of Nosara and a 3.4-magnitude quake at 8:41 p.m. 14 miles west of the community in the Pacific.

The Laboratorio de Ingenieria Sismica had slightly different estimates of magnitude.

It said that the 6:03 p.m. quake was felt strongly in Nosara to the extent that there might be minor damage.

It also said the quake was felt strongly in Carmona, Nandayure, and less so at other points on the peninsula and as far away as Nuevo Arenal.

The Observatorio attributed the quake to subduction of the Coco tectonic plate under the lighter Caribbean and said the quake was felt in the Central Valley.

Later in the evening the Red Sismológica Nacional reported a 10:04 p.m. quake some 19 kilometers west of Sámara, which is south of Nicoya on the far Pacific coast. But that quake was just 2.3 magnitude, it said.
