Earthquakes’ sudden, rapid shaking can cause fires, tsunamis, landslides or avalanches. They can happen anywhere, but they’re most common in Alaska, California, Hawaii, Oregon, Puerto Rico and Washington, according to the Department of Homeland Security.

The upcoming storm is likely to pose a higher risk for mudslides, debris flows and flooding than the rainfall this past week.

Forecasters said excessive rainfall could lead to flash flooding and debris flows in recent burn scars, including the Eaton and Palisades fires.
