MEXICO CITY -- One person was killed and 12 others were injured after a 6.5-magnitude earthquake struck southern Mexico on Friday, local authorities said.

During an evacuation prompted by the earthquake, a man in his 60s died after stumbling and losing consciousness in Benito Juarez municipality, Mexico City, an official statement from the municipality showed.

Clara Brugada, head of government of Mexico City, said on X that after activating the earthquake response protocol, the latest report indicated 12 people injured, as well as 18 complaints due to a lack of electrical supply in various neighborhoods.

She added that two structures were being evaluated for risk of collapse, and 34 buildings and five homes were being inspected as a preventive measure.

Mexico's National Seismological Service said the quake occurred at 7:58 a.m. local time (1358 GMT), with the epicenter located about 4 km southwest of San Marcos in the southern state of Guerrero, at a depth of approximately 5 km.

In Mexico City, loudspeakers on the streets broadcast a seismic alert several seconds before the tremors were felt.
