A 4.8-magnitude quake took place Monday at 2:02 p.m. The epicenter was estimated to be in the upper gulf of Nicoya about 20 kilometers above Puntarenas Centro and just west of Playa Costa de Pajaros, according to the Laboratorio de Ingeniería Sísmica. Earlier story below.
That bump may not have been the St. Patrick’s Day party next door. The country experienced a wave of earthquakes over the weekend.
Friday was only 13 minutes old when a 3.7 quake rattled the Jacó area. At 4:22 a.m. a second quake took place in about the same area, northeast of Playa Hermosa. It was estimated at 3.4 magnitude.
Then at 5:33 a.m. there was a 3.5 quake just 5.4 kilometers north of Golfito centro. That is less than 3.5 miles. At 7:22 a.m. a 3.8 quake took place up the coast near Dominical. There have been a number of similar quakes in this area for the last month, noted
the Laboratorio de Ingeniería Sísmica.
Saturday saw three quakes, but these were inland. A 3.9 or 4.2 magnitude quake took place five miles northeast of Pinol de Upala in Alajuela. That is close to the Nicaraguan border. That was at 9:21 a.m. That night two 3.1 magnitude quakes took place only seconds apart at about 8:31 p.m. Both were about 20 kilometers, about 13 miles, north of San Ramón near the community of San Jorge. The Red Sismológica Nacional attributed these to subduction of the Coco Tectonic plate by the Caribbean plate.
Then Sunday at 6:57 p.m. there was a 3.2 quake about 9 kilometers south southwest of Ciudad Neily in southern Costa Rica. That was followed by a 3.1 magnitude quake at 7:21 p.m. near the border with Panamá.
