Mexico: A magnitude-5.0 earthquake occurs in southern Oaxaca State at around 08:40 Jan. 18

A magnitude-5.0 earthquake occurred in southern Oaxaca State at around 08:40 Jan. 18. The epicenter was about 12 km (7 miles) east of Santa Maria Zapotitlan. The tremor occurred at a depth of about 46 km (29 miles), and light shaking was probably felt throughout much of Oaxaca and parts of southern Veracruz and western Chiapas states. There have been no initial reports of damage or casualties as a result of the earthquake; however, significant damage is unlikely. It could take several hours until authorities can conduct comprehensive damage assessments, especially in remote areas. Light aftershocks are likely over the coming days.

Officials may temporarily shut down transportation infrastructure in the tremor zone to check for damage. Minor disruptions could occur during shutdowns, but service will likely resume quickly if no damage is found. Utility outages are possible, particularly near the earthquake's epicenter.
