The US Geological Survey said the two quakes occurred at almost the same spot, just offshore from the Mexico-Guatemala border.

It was unclear if the 5.4 quake at 11:30 a.m. UTC on Wednesday was an aftershock of the 6.3 temblor at 4:27 a.m. UTC.

The civil defense office of the southern state of Chiapas said no damage was immediately reported.
