Just another average month with some 372 earthquakes registered

There were 372 earthquakes under Costa Rican territory during the month of February. But just eight were strong enough to draw reports that residents felt one.

As expected, the quakes are mostly to the west side of the country along the Pacific coast where tectonic plates push and shove continually.

The Observatorio Vulcanológico y Sismológico de Costa Rica at Universidad Nacional said that the distribution of some quakes was in the vicinity of the strong Sept. 5, 2012, Nicoya quake and another Jan. 17. The felt quakes ranged from a magnitude of 2.2 to 4.6 during February. Two of the biggest were in the Pacific off Jacó.

The Cocos tectonic plate continues to push under the lighter Caribbean plate, which is the reason for many of the country’s quakes.

The number of quakes is not unusual for a month. Quake investigators have installed systems of sensors that pick up the slightest trembling. Using them they hope some day to be able to be more precise in predictions.
