SAN JOSE — A powerful earthquake shook southern Costa Rica near the border with Panama on Friday evening, toppling items from store shelves and knocking out power in places, but authorities said there was no major damage or reports of serious injuries.

The US Geological Survey said the magnitude 6.1 quake struck at 5:22 p.m. at a depth of about 12 miles. Its epicenter was about 12 miles north of the town of Golfito. The USGS initially estimated the magnitude at 6.0.

Alexander Solis, president of the National Emergencies Commission, said there were a handful of localities where power failed and objects fell without serious consequences. He said hospitals were only reporting some people having suffered panic attacks.
