Mexico: Magnitude-5.4 earthquake occurs offshore of Salina Cruz at 1156 Dec. 8; no immediate reports of damage or injuries

Event

A magnitude-5.4 earthquake occurred offshore of Oaxaca, Mexico at 1156 Dec. 8. The epicenter was about 10 km (6.2 miles) south of Salina Cruz. The tremor occurred at a depth of about 25.6 km (15.9 miles), and weak-to-light shaking was probably felt throughout the parts of Oaxaca, Veracruz, and Chiapas states, Mexico, including in Salina Cruz and Oaxaca. There have been no initial reports of damage or casualties, and significant damage is unlikely. It could take several hours until authorities can conduct comprehensive damage assessments, especially in remote areas. 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.

Advice

Plan accordingly for aftershocks. Consider vacating multistory buildings if operating in affected areas until authorities confirm their structural integrity. Allow additional time for air and road travel, as aftershocks may prompt brief disruptions. Seek updated information on road conditions before driving in hilly areas in the affected region due to potential landslides.
