MEXICO CITY, Sept 23 (Reuters) - A strong earthquake struck off Mexico's Pacific coast late on Tuesday, the U.S. Geological Survey said, but no tsunami warning was issued and there was no immediate report of damage.

The quake, measuring 6.4, hit 113 miles (181 km) southwest of Manzanillo, Colima, at a depth of 25.9 miles (41 km) at 7:33 p.m. local time (0233 GMT), USGS said. It was the second quake to shake Mexico's Pacific coast on Tuesday.

"We did not feel anything," said a receptionist at Las Hadas Golf resort and Marina in Manzanillo. "Obviously there was no quake evacuation, nothing."

Earlier Tuesday a quake, measuring 5.2, shook the famous Pacific coast resort of Acapulco. Local seismological authorities said it hit 35 miles (56 km) southeast of the resort, known for its horseshoe bay and cliff divers.

No damage or deaths were reported from the first quake. (Reporting by Chris Aspin and Miguel Angel Gutierrez, editing by Jackie Frank)
