Costa Rica was shaken by a 6.8 magnitude earthquake at 8:28 pm (local time), with an epicenter approximately 15 km southwest of the Central Pacific beach town of Esterillos, according to the Volcanological and Seismological Observatory of Costa Rica (OVISCORI). The USGS has it listed as a 6.5 mag.
Local residents reported feeling the quake strongly in the Central Valley, where buildings swayed and some residents headed out into the streets. Reports of the shake came in as far away as Puerto Viejo de Limón on the opposite coast.
A resident living in the Jacó area, near the epicenter of the major quake and two aftershocks, said that people there had reported artwork and other objects falling from the walls and breaking. Reports from Playa Hermosa, even closer to the epicenter, reported that while the experience was certainly terrifying, electricity was still on and no damage was visible from her vantage point.
