Tectonic plates generate plenty of quakes

The Cocos tectonic plate kept grinding against the lighter Caribbean in the last few days and generated at least 39 significant earthquakes, according to the Red Sismológica Nacional.

The bulk of the quake epicenters were 40 to 60 kilometers (25 to 37 miles)  southwest of  Savegre de Quepos. However, beginning early Sunday a new focus developed 10 to 20 kilometers (6 to 12 miles) south of Quepos.

At the first area there were eight quakes with magnitudes greater than 4.0, said the Red Sismológica. One Thursday was 5.1 and a second Saturday was 5.3. Both of these were felt on land, including in the Central Valley.

At the area closer to Quepos, the quake with the biggest magnitude was one of 4.0 that took place Sunday at 5 a.m., the Red Sismológica noted.
