MEXICO CITY (AFP) - A 5.4-magnitude earthquake rattled southeastern Mexico on Saturday, seismologists said.

The quake was centered in the state of Veracruz, 47km south-east of Sayula de Aleman, the US Geological Survey (USGS) said.

Mexico's National Seismology Service initially measured it at a strong 6.2-magnitude but later revised it to 5.6 strength.

The USGS said the quake was 145km deep, much farther underground than Mexico's preliminary measurement of 10km.

National Civil Protection coordinator Luis Felipe Puente said no damage was seen when authorities checked the region.
