The Laboratorio de Ingeniería Sísmica said earlier today that a 4.2-magnitude quake took place at 4:04 a.m. The epicenter was estimated to be about 14.6 kilometers or about 9 miles due east of Nicoya Centro on the Nicoya peninsula. In fact, the epicenter was estimated by the Universidad de Costa Rica agency as being 40 kilometers directly under the highway that leads from the Puente de Amistad to Nicoya.
Earlier in the day at 2:32 p.m. there was a 3.9-magnitude quake in the hills of the northern Pacific coast some 9 kilometers (5.5 miles) south southwest of San Mateo Centro.
Both quakes appear to have been felt just locally and not in the Central Valley.
