Originally registered as a 6.4-magnitude temblor, Mexico’s National Seismology Service (SSN) recalculated the quake’s strength at magnitude 6.0 and at a depth of 8 kilometers.
No casualties have been reported, but the quake caused minor damage to buildings in Pacific Coast communities near the epicenter in the town of Pinotepa Nacional in the state of Oaxaca, says Victor Hugo Espindola, seismologist at the SSN.
The earthquake occurred at 2:22 a.m., 120 kilometers from Oaxaca city and 355 kilometers south/southeast of Mexico City, said the US Geological Survey, which calculated the quake at 6.2 magnitude with the epicenter at a depth of 20 kilometers.
