The epicenter of the 5.1 quake was also located in Guanacaste, 151 kilometers west of the capital San Jose, and 14 kilometers beneath the earth's surface, seismic experts said. Aftershocks as strong as 6 on the Richter scale are normal as shifting tectonic plates release energy following an earthquake of major magnitude, like the quake on Wednesday, said the experts.
