On Tuesday a magnitude-7.3 earthquake shook the impoverished country of Nepal, this is the second earthquake to hit the impoverished country in less than a month. On Wednesday, officials with bullhorns walked through the badly damaged streets of Chautara, a small town northeast of Kathmandu, calling for people to leave buildings in danger of collapsing.

“Damaged houses were further damaged or destroyed. Houses and school buildings spared before were affected yesterday, roads were damaged,” said Jamie McGoldrick, a top U.N. official in Nepal.

“There is danger!” officials said over bullhorns. “Leave the buildings!”

Many buildings that were damaged in the first earthquake were now a major concern for collapse.

“We were in the shop. All of a sudden the building shook. I jumped out of the store and the next second it fell down. It was already tilted by the last month’s earthquake. I watched it just slide and fall on its side,” said Devi Acharya, a convenience store owner.

Tuesdays magnitude-7.3 quake killed at least 79 people and injured more than 2,300. The magnitude-7.8 earthquake that hit April 25 killed more than 8,150 people and flattened entire villages, leaving hundreds of thousands homeless in the country’s worst quake since 1934.

The U.S. Geological Survey said Tuesday’s earthquake was the largest aftershock of the April quake. But it was significantly less powerful and occurred deeper in the Earth. Working from USGS data, calculations done by University of Michigan earthquake geophysicist Eric Hetland indicated that about 65,000 people were exposed to “violent” shaking Tuesday, compared to 1.5 million on April 25.
