An earthquake of magnitude 5.8 struck the Michoacán region in Mexico on Tuesday, a day after two people were killed in another powerful quake.
Monday’s earthquake, measured at a magnitude of 7.6, stuck on the anniversary of two previous earthquakes that caused enormous damage and killed hundreds or thousands of people in 1985 and 2017.
One of the victims died after being crushed by the facade of a department store in the Pacific port of Manzanillo, while another was found dead at a mall.
The tremor passed without that level of tragedy, despite heightened nerves from a nationwide annual earthquake drill that occurred less than an hour before.
The tsunami alert, which was issued immediately after the quake, was revised later in the day.
Authorities said the tsunami threat has “largely passed”, with minor sea fluctuations of up to 0.3 metres above and below the normal tide to continue for the next few hours.
