A strong 6.2-magnitude earthquake off Mexico's Pacific coast state of Jalisco produced no immediate reports of damage or injuries, civil protection authorities said Sunday.

Santos Munoz, a spokesman for the Jalisco State civil protection agency, said that an early survey of the coast turned up no problems. The agency's Twitter account reported that the quake was felt slightly in some Jalisco communities, but no damage was reported.

The U.S. Geological Survey reported that the quake occurred at around 8:23 a.m. local time (1423 GMT) Sunday.

It was registered at a depth of 6 miles, about 131 miles southwest of the community of Tomatlan, and 503 miles west of Mexico City.
