Summary
Three people were injured in Chiapas after a 7.3-magnitude earthquake struck off southern Mexico, with no deaths reported and damage so far limited to gas leaks, cracked walls and fallen ceiling panels.
USGS placed the epicenter 48 km southwest of Aquiles Serdán in Chiapas, and multiple aftershocks followed, including one of preliminary magnitude 6.0.
Mexico said there was no serious damage, though the navy warned beach water levels could rise by up to 0.5 meter and urged people to stay away from the coast.
Guatemala recorded a few tsunami waves under 1 meter above tide level, suspended classes in several western regions and reported damaged facades and other collapses; El Salvador reported no damage.
The Pacific Tsunami Warning Center first warned of hazardous waves within 300 km of the epicenter, then later said the threat had passed.
