At least two homes in the Studio City neighborhood were left with “significant” damage after being struck by a “debris flow,” the Los Angeles Fire Department said Sunday night. 

More than a dozen residents and their pets were evacuated from all nine homes on Lockridge Road, the department said.

“LAPD/EMD are working together to offer emergency shelter locations to residents” if needed, the department said. 

Debris flows are “fast-moving landslides” that can occur during periods of intense rainfall, according to the US Geological Survey.
