A powerful, magnitude-7.6 earthquake has shaken Costa Rica and prompted tsunami warnings. There are no reports so far of damage or injuries.
The U.S. Geological Survey says the quake struck about 38 miles from the town of Liberia and 88 miles west of the Costa Rican capital, San Jose. It was centered about 25 miles below the surface.
In the coastal town of Nosara in northwestern Costa Rica, trees shook violently and light posts swayed. Teachers chased primary school students outside.
A tsunami warning was in effect for Costa Rica, Panama, Nicaragua, El Salvador, Honduras, Mexico, Colombia, Ecuador, Guatemala and Peru and a tsunami watch was in effect for Chile. The Pacific Tsunami Warning Center said it was unknown if a tsunami was generated, but the warning was based on the size of the earthquake.
