There were no immediate accounts of injuries, but communications were down in many areas.
The USGS said the 8:42 a.m. quake struck about 38 miles from the town of Liberia and 88 miles west of the capital, San Jose.
It was centered about 25 miles below the surface.
The magnitude initially was estimated at 7.9.
