A 6.0-magnitude earthquake struck off Mexico's Pacific coast close to the Guatemalan border on Sunday, but there were no immediate reports of damage or casualties.
The quake occurred at 6:22 am (1222 GMT) at a depth of 35 kilometers (21 miles), and was located 28 kilometers (17 miles) south-southwest of Suchiate, Mexico, the US Geological Survey said.
"The quake was felt across most of the Soconusco region," civil protection official Luis Manuel Garcia told AFP. "We have no reports of damage for the moment."
The Pacific Tsunami Warning Center did not issue a report on the quake.
A powerful 7.4-magnitude earthquake rocked southwest Mexico on March 20, killing two people, injuring 13 others and damaging thousands of homes.
That earthquake -- with its epicenter south of the Pacific resort of Acapulco -- was the most powerful to hit the country since one in 1985, which destroyed entire neighborhoods of the capital and killed thousands of people.
