Mexico: Magnitude-5.4 offshore earthquake occurs in the Pacific Ocean west of Colima at around 13:05 April 21

A magnitude-5.4 offshore earthquake occurred in the Pacific Ocean west of Mexico at around 13:05 on April 21. The epicenter was about 160 km (100 miles) south-southwest of Manzanillo, Colima State. The tremor occurred at a depth of about 10 km (6 miles), and moderate shaking was probably felt near the western coast of Jalisco, Colima, and Michoacan 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.
