The first tremor of 2013 was recorded at 1:54 a.m. with a magnitude of 2.7 degrees and an epicenter located in Golfito, on the South Pacific coast. By noon 6 temblors were registered by the Volcanological and Seismological Observatory of Costa Rica (Ovsicori).
Five of the tremors had epicenters located in the South Pacific, near the border with Panama.
At 2:06 a.m. came the second, with a magnitude of 2.6 degrees, located 4 km southeast of Corredores. Five minutes later, at 2:11 a.m., came the third, a 2.4 degrees recorded near Golfito.
At 5:33 a.m, another tremor shook Golfito with a magnitude of 2.6 degrees.
The last earthquake in the region, a magnitude-2.4, was registered by Ovsicori at 5:48 a.m., also in Golfito.
Then at 10:12 a.m., a 2.6 quake was felt in El Guarco, in the province of Cartago. There are no reports of damage in any of these locations.
Ovsicori experts agree that a series of faults were activated in Costa Rica’s southern region after the magnitude-7.6 earthquake that hit Nicoya, Guanacaste last October 5.
