Mexico: Magnitude-5.7 earthquake occurs in Guerrero State at around 2103 CST March 20

Event

A magnitude-5.7 earthquake occurred in Guerrero State in southwestern Mexico at around 2103 CST March 20. The epicenter was about 8 km (5 miles) north of Marquelia. The tremor occurred at a depth of about 28 km (17 miles), and moderate shaking was probably felt near the epicenter in Guerrero State; weak-to-light shaking likely occurred throughout southwestern Mexico, including Puebla and Morelos, as well as parts of southern Mexico and western Oaxaca states. There have been no initial reports of damage or casualties as a result of the earthquake. It could take several hours until authorities can conduct comprehensive damage assessments, especially in remote areas. Aftershocks are possible 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.
