An earthquake with a preliminary magnitude of 7.1 hit Mexico City Tuesday afternoon, the United States Geological Survey reported, causing the façades of dozens of buildings in the capital to crumble. Though the full extent of the damage is not yet known, the governor of the state of Morelos tweeted Tuesday afternoon that at least 42 people were killed in the aftermath.*
The Survey also noted that the epicenter of the earthquake was located in Puebla, about 85 miles from the capital.
The quake comes just 11 days after a magnitude 8.2 earthquake—the strongest to hit Mexico in a century—rocked the southern part of the country, resulting in the deaths of over 60 people.
