For two days in a row, the Nicoya peninsula and Guanacaste area has been rocked by earthquakes.
A 4.0-magnitude quake took place off Montezuma on the tip of the peninsula at 11:12 a.m. Tuesday. Wednesday at 12:27 p.m. a 3.7-magnitude quake was reported 12 kilometers southeast of Filadelfia further north.
Both quakes were blamed on local faults, but the
Montezuma quake, estimated to be 16 kilometers southeast of Cóbano is in an area where quakes have taken place repeatedly.
The Observatorio Vulcanológico y Sismológico de Costa Rica at Universidad Nacional in Heredia made both estimates. The Red Sismológica Nacional at the Universidad de Costa Rica estimated the magnitude to be 4.1 for the Tuesday quake and 3.9 for the quake Wednesday.
