The 7.1 magnitude quake killed more than 200 people and many others are still missing. That includes at least 21 children and 4 teachers who were killed when an entire wing of an elementary school collapsed.
Dozens of homes, office buildings and other structures have been flattened and rescuers continue the search for survivors.
Thousands of people flooded into the streets as the buildings began to tremble.
It happened on the 32nd anniversary of the biggest quake to ever strike the country's capital. The quake of 1985 killed thousands.
