MEXICO CITY (AP) _ More than 1,300 mud-brick homes were damaged in an earthquake in southern Mexico, forcing peasants in the mountainous region to sleep in the streets, officials said Tuesday.

Monday's earthquake also caused some Mexico City office buildings to sway and thousands of residents to rush out of their workplaces Monday. It came one week after a 6.7-magnitude quake killed at least 17 people in Mexico.

Television footage showed gaping holes in roofs where tiles and wood beams had collapsed, and large cracks splitting open the mainly houses in Coahuyutla, about 190 miles southwest of Mexico. No injuries were reported in the town, 30 miles from the quake's epicenter.

The 5.7-magnitude quake Monday damaged more than 1,300 homes, 350 of them severely. Mexican army troops and state officials traveled to the area to help residents reconstruct their dwellings.

A 4.7-magnitude quake struck the coastal region of the southern state of Chiapas on Tuesday afternoon, but there were no reports of damage or injuries.
