A steady debris flow is also likely responsible for the damage.

The homes were evacuated because of partial undermining of the soil beneath the houses, says Los Angeles fire Department spokeswoman Amy Bastman.

One of the homes has a patio deck that partially collapsed, It was unclear how much foundation the home and patio share. KCAL9’s Tom Wait said this home was yellow-tagged.

Neighbors told CBSLA that the other home is vacant.

The concern is that debris from these homes is now coming down on homes below it.

Wait said neighbors are concerned because the hillsides are already saturated.
