Rescuers ask onlookers for “Silence” to help them comb quickly and efficiently through the rubble of a quake-toppled building in the Mexican capital.

Rescuers work tirelessly to locate survivors in the aftermath of the 7.1-magnitude tremor that struck at 1:14pm local time on Tuesday, killing at least 224 people.

The tremor rocked Mexico City just hours after earthquake safety exercises were conducted, as they are annually, on the anniversary of a 1985 earthquake that claimed thousands of lives in the city.

The Enrique Rebsamen school in Mexico City partially collapsed in the earthquake, leaving at least 26 dead, including 21 pupils between the ages of seven and 13 and five adults. Between 30 and 40 people are still missing at the site, according to emergency authorities.
