Landslides, also known as mudslides or debris flow, occur frequently in Orange County. These disasters can be caused by a variety of factors including earthquakes, storms, and fires. Landslides can occur quickly, often with little notice, and the best way to prepare is to stay informed about changes in, and around, your home that could signal a potential landslide. Also, be sure to exercise caution when traveling through areas where mudslides have recently occurred because of heavy debris, mud, and flooding.

Areas that have destroyed vegetation due to wildfires, or human modification, and locations that have experienced mudslides before are more likely to experience landslides. You can learn whether landslides have occurred previously in your area by contacting local authorities or a county geologist.

  • Learn if your area has been previously affected by landslides or debris flow by contacting local authorities. 

  • Develop emergency plans for your family and business. 

  • Listen to the radio or local alerting systems for information and instruction regarding landslides. 

  • Stay away from the affected area. Additional debris flow may occur after the initial landslide. 

  • Move to high ground away from the affected area. If a landslide is approaching you, run for the nearest shelter and take cover.
