An earthquake with a magnitude of 7.4 shook Mexico on Monday, according to preliminary data, with further details unavailable at the moment.

The quake came less than an hour after a national drill was held to mark the 37th and fifth anniversaries of the earthquakes that fell on the same date in 1985 and 2017, respectively, which caused heavy material and human damage in the country.
