Monster storm triggered hundreds of mudslides across Los Angeles. Why do they happen?
Briefly

"Our hillsides are already saturated. So even not-very-heavy rains could still lead to additional mudslides," said Mayor Karen Bass. "Even when the rain stops, the ground may continue to shift."
"The areas most prone to mudslides are those on or near hillsides, especially those charred by wildfires in recent years that have little vegetation to hold the soil in place," says the California Department of Conservation.
