Some of the people in their pajamas run out of their apartments to get to safety. In the Mexican capital, the ground trembles in the morning.
The earthquake alarm went off in the capital at around 8:30 a.m. (local time), and people left their homes. So far there have been no reports of damage, Mexico City Mayor Claudia Sheinbaum tweeted.
Mexico is located on the so-called Pacific Ring of Fire, the most geologically active zone on earth, where different tectonic plates meet. The area extends from the South American west coast across the west coast of the USA, Russia and Japan to Southeast Asia and New Zealand. About 90 percent of all earthquakes occur there. Mexico City, one of the most populous cities in the world, repeatedly experiences strong earthquakes - most recently in September one with a magnitude of 7.7, in which two people died.
