A 7.1 magnitude earthquake struck Mexico City on Tuesday, killing at least 200 people. More than three dozen buildings crumbled to the ground in Mexico City, and residents scrambled to dig through rubble.

The earthquake came on the 32nd anniversary of a quake that killed upwards of 10,000 people in the nation, and less than two weeks after an 8.1 magnitude quake left at least 100 dead in the country.

Dudley Althaus, a reporter for The Wall Street Journal's Mexico Bureau, and Jorge Guajardo, Mexican ambassador to China from 2007 to 2013 and consul general to Mexico in Austin, Texas from 2005 to 2007, bring us the latest.
