An earthquake of magnitude shook Mexico’s central Pacific coast on Monday which killed at least one person and set off a seismic alarm in the rattled capital on the anniversary of two earlier devastating quakes. There were some early reports of damage to buildings from the quake, which hit at 1:05 p.m. local time, according to the U.S. Geologic Survey, which had initially put the magnitude at 7.5. It said the quake was centered 37 kilometers (23 miles) southeast of Aquila near the boundary of Colima and Michoacan states and at a depth of 15.1 kilometers (9.4 miles).
Mexico’s National Civil Defense agency said that based on historic data of tsunamis in Mexico, variations of as much as 32 inches (82 cm) were possible in coastal water levels near the epicenter. The U.S. Tsunami Warning Center said that hazardous tsunami waves were possible for coasts within 186 miles (300 kilometers) of the epicenter. Alarms for the new quake came less than an hour after a quake alarms warbled in a nationwide earthquake simulation marking major, deadly quakes that struck on the same date in 1985 and 2017.
