A home in Claremont was reduced to a charred shell after an explosion was reported there on Monday.
Firefighters were called about an explosion on the 200 block of West 12th Street shortly before 2 p.m., said Los Angeles County Fire Department Supervisor Melanie Flores.
Crews were on the scene in fire attack mode, Flores said, but by the time Sky5 was above the scene around 3:30 p.m., the home appeared to be completely destroyed.
The flames appeared to be contained to the home they originated in, the aerial video showed.
No injuries were reported, according to Flores.
The fire's cause was under investigation, and although it was reported as an explosion, it's unclear exactly what led up to the large blaze.
Neighbors described it as feeling like an explosion, with some saying they could actually feel the impact even houses away. "It's just like a bomb went off," one nearby resident told KTLA.
"I thought we were having an earthquake at first," she said.
Another woman who lives nearby, Molly Perez, said her neighbor Nancy was taken aback by the reported explosion — literally.
"She was sitting on her back porch and she about got thrown back, off of her feet," Perez said.
Meanwhile, the owner of the home said no one was home at the time and he's not sure what could have caused the incident.
"I'm grateful that I was not home and that there was nobody else was in the house at the time," said Ron Podojil. "And I'm glad nobody got hurt."
"I just have no idea why it did," he said of the house catching fire.
There were reports of downed wires and a gas leak in the area, but they had not yet been linked to the fire, officials said.
Firefighters remained on the scene Monday afternoon, and no further details were immediately available.
