Major earthquake shakes Mexico on anniversary of two previous tremors

A magnitude 7.5 earthquake has struck western Mexico on the anniversary of two earlier devastating tremors, killing at least one person and causing flooding on the Pacific coast.

The quake hit at 1.05pm local time, striking near the town of La Placita de Morelos in the state of Michoacán at a depth of 15km.

President Andrés Manuel López Obrador said on Twitter that the secretary of the navy told him one person was killed in the port city of Manzanillo, Colima when a wall at a mall collapsed.

Michoacán authorities said there were no immediate reports of significant damage in that state beyond some cracks in buildings in the town of Coalcomán.

A mandatory evacuation order was issued in Mexico City, but the mayor, Claudia Sheinbaum, said that so far there had been no reports of damage in the capital.

The US Tsunami Warning System said there was risk of a tsunami near the coast , and footage posted on social media appeared to show flooding in the city of Manzanillo.
