A 6.5-magnitude earthquake struck in Mexico’s western Guerrero state Saturday night, shaking buildings and causing panic in the nation’s capital and the Pacific resort of Acapulco. Officials said at least three people died, but there were no reports of widespread damage.

The U.S. Geological Service initially estimated the quake at magnitude at 6.8, but downgraded it to 6.7 and then 6.5. A quake of that magnitude is capable of causing severe damage.

The USGS said the quake occurred 40.3 miles deep and was centered about 26 miles southwest of Iguala in Guerrero. That is 103 miles south-southwest of Mexico City.

Mexico’s Interior Department said the quake was felt in parts of nine states.
