Residents feel quakes in Orosi and along the Pacific coast

A mid-afternoon quake that was about eight kilometers southeast of Orosi de Paraiso got the attention of the downtown office workers Tuesday.

The Laboratorio de Ingeniería Sísmica said that the cause was a local fault and that moderate events sometimes cause more damage than big ones. The magnitude was estimated at 4.0 by the Laboratorio and 4.4 by the Red Sismológica Nacional. There were no reports of serious damage.

The 3:29 p.m. quake was just the beginning. There was a second quake in about the same area at 9:40 p.m. and the Red Sismológica Nacional said the magnitude was 3.0. The Laboratorio said 2.8.

At 9:21 p.m. a 4.7 quake took place just inland from the Pacific on the Nicoya peninsula. The epicenter was estimated to be between Sámara on the south and Nosara on the north, said the Laboratorio.

And then at 10:42 p.m. another 4.7 magnitude quake took place, but this one was well out in the Pacific off the coast of the peninsula. The Red Sismológica Nacional said the epicenter was 230 kilometers southwest of Sámara. This last Pacific coast quake was attributed to movement within the Coco tectonic plate, said the Red.
