ACAPULCO, Mexico — A strong earthquake shook the southern Pacific coast of Mexico as well as the capital and several inland states Thursday, sending frightened people into unseasonal torrential rains that were also bearing down on the coast.
The 6.4-magnitude quake in southern Guerrero state was centered about 9 miles (15 kilometers) north of Tecpan de Galeana, according to the U.S. Geological Survey, and was felt about 171 miles (277 kilometers) miles away in Mexico City, where office workers streamed into the streets away from high-rise buildings.
There were no reports of injuries but varying reports of damage near the epicenter emerged throughout the day.
Among the damage was the collapse of a 30-meter (yard) section of highway bridge that was already under repair from last fall's flooding and a magnitude-7.2 quake in the same area in April. Flooding of the detour route from heavy rain Thursday left the federal highway between the resort cities of Acapulco and Zihuatanejo closed.
Guerrero Gov. Angel Aguirre reported three homes collapsed in Zijuatanejo and 17 more unstable after the temblor. Local officials reported dozens of simple adobe homes collapsed near the epicenter, though no one was injured. Aguirre also reported mudslides on other major highways, including the one connecting Acapulco with Mexico City.
Civil protection crews in Acapulco found no problems except scared citizens who were forced to take refuge in the heavy rain that was hitting the region.
In Mexico City, elegantly dressed businesswoman Carmen Lopez was leaving a downtown office building when the ground began to shake. She dashed across the street to a leafy median as light poles swayed violently above her.
"That was just too scary," Lopez said as she quickly started dialing her cellphone to alert friends and family.
Behind her, thousands of people poured from neighboring office buildings, following pre-planned evacuation routes to areas considered safe in case of falling glass.
