The two quakes shook buildings, breaking windows and sending panicked residents fleeing into the streets. One man was reported killed and two people seriously hurt in the panic.
The first jolt struck at 08:29 local time, and had a magnitude of 6.8 to 7.0. The epicenter was about 64 kilometers east of the resort city of Acapulco. It was felt in the southwestern Mexican states of Oaxaca, Guerrero and Puebla.
The Mexico City Seismological Institute said the quake measured 7.0 on the Richter scale but scientists with the US Geological Survey in Golden, Colo., said the temblor measured 6.8. A quake measuring six and above is capable of causing severe damage.
