Tables shook and walkers stopped in their tracks in at least one town on the central Pacific Saturday night as an earthquake measuring 4.1 on the Richter scale shook the ground.

The quake occurred at 7:38 p.m. and originated 11 kilometers northwest of Quepos, on the central Pacific coast, according to a statement from the Volcanological and Seismological Observatory of Costa Rica (OVSICORI), based at Universidad Nacional (UNA) in Heredia, north of San José.

It was reported by residents in the central Pacific, the Southern Zone town of Pérez Zeledón and in Puriscal, southwest of San José.

At one restaurant in the central Pacific beach town of Esterillos Este, diners put down their forks and looked at each other with startled expressions reading, “Is that an earthquake?” as the ground rocked beneath them. A few moments later, normalcy resumed.
