(Reuters) - A strong, 6.6 magnitude earthquake struck off the coast of Chile on Tuesday, the U.S. Geological Survey said.
The quake, initially reported as a magnitude 6.8, was at a fairly shallow depth of 23.6 miles (38 km) under the seabed. Its epicenter was 67 miles (108 km) northwest of Coquimbo.
The earthquake did not trigger a tsunami, the Pacific Tsunami Warning Center said.
