PORTLAND – A mud slide hit a house and injured five people during heavy rainfall in Lake Oswego early Friday morning.

A man inside the home when it happened decribed the scene to KGW.

"It was like a movie, where you see explosions, and everything's flying... except a million times faster," Omar Elnaser said. "It was crazy. I thought in a split second we were all gonna die. I thought everybody was gonna die."

Around 1 a.m., the ground broke loose and the mud slide slammed right into a house located at 17661 Woodhurst Place in Lake Oswego.

"We saw a burst of mud, and after that the whole wall just... came right in at us... we had no time to do anything... everything just came in at us like a car at over 100 miles per hour."

The mud flowed downhill, across a road and then down again into the house. Family members called 9-1-1 and said they were trapped inside, with mud filling the first floor. But they eventually managed to scramble out a window.

Five people inside the home were hurt, three of them seriously. They were taken to a trauma unit at an area hospital.

Meantime, residents in 20 other homes in the Woodhurst Place neighborhood were evacuated and authorities said mud continues to flow down the street.

"We heard some pounding, our dog was barking the doorbell rang," said Charlie Gibbs, who was evacuated from his nearby home. "Police were saying 'you've got 10 minutes to get out of here,' so we just grabbed a few things and took off."

Gert Zoutendijk with the Lake Oswego Fire Department also said that “a strong smell of natural gas was present.”

Investigators think the slide came down from above Green Bluff in Lake Oswego and hit the home from behind.

“The mud had so much force, it pushed an SUV that was parked in the garage outside,” Zoutendijk said.

Elsewhere, a mudslide was reported on Highway 101 near Cloverdale and another slide was blocking Highway 26 near Brightwood.

The last time a major mud slide made the news was when several Southwest Portland homes were damaged back in October of 2008. In that emergency, ground underneath a residence at 6438 SW Burlingame Place became unstable, causing the home to slide down a steep hill and crash into two other structures below.
