A moderate earthquake of magnitude 5.7 shook the hilly southern Mexican state of Chiapas on Thursday, but no injuries or serious damage were reported.

The earthquake was centered off Mexico's southern Pacific coast, 60 miles (100 km) west of the city of Tapachula at a depth of 49 miles (79 km), the U.S. Geological Survey said.

"The epicenter was near the west coast, but the emergency services there have no reports of damage," said civil protection official Alicia Saucedo in the state capital of Tuxtla Gutierrez.

A magnitude 5.7 tremor usually causes only minor damage to buildings. Several moderate quakes have shaken Chiapas, home to many poor indigenous communities, in recent weeks.
