A house collapsed Sunday around 6 a.m. in the Mantua neighborhood of Philadelphia, sending neighbors fleeing from their homes into the early morning rain, officials said.

No one was home when the house crumbled. Neighbors told NBC10 the owner was likely at work. Meanwhile, framed photographs and paintings could be seen hanging from the exposed walls.

Officials also checked on two adjoining properties for injured residents and potential damage. First responders told NBC10 that 13 people fled from two of the neighboring houses, located on the 3900 block of Aspen Street.

"It's just terrible. I've never seen anything like that," neighbor Connie Lawhorn said. "Thank God that nobody was at home."

Lawhorn didn't hear any loud noises when the house collapsed, but neighbor Crystal Nelson told NBC10 she heard a loud boom and thought a tree had fallen.

"You would not believe that something like this can happen," she said.

No injuries were reported.
