LAND SLIDE

During a Landslide:

  • Stay alert and awake. Many debris-flow fatalities occur when people are sleeping. Listen to a Weather Radio or portable, battery-powered radio or television for warnings of intense rainfall. Be aware that intense, short bursts of rain may be particularly dangerous, especially after longer periods of heavy rainfall and damp weather.
  • If you are in areas susceptible to landslides and debris flows, consider leaving if it is safe to do so. Remember that driving during an intense storm can be hazardous. If you remain at home, move to a second story if possible. Staying out of the path of a landslide or debris flow saves lives.
  •  Listen for any unusual sounds that might indicate moving debris, such as trees cracking or boulders knocking together. A trickle of flowing or falling mud or debris may precede larger landslides. Moving debris can flow quickly and sometimes without warning.
  • If you are near a stream or channel, be alert for any sudden increase or decrease in water flow and for a change from clear to muddy water. Such changes may indicate landslide activity upstream, so be prepared to move quickly. Don’t delay! Save yourself, not your belongings.
  • Be especially alert when driving. Embankments along roadsides are particularly susceptible to landslides. Watch the road for collapsed pavement, mud, fallen rocks, and other indications of possible debris flows.

What to Do if You Suspect Imminent Landslide Danger:

  • Contact your local fire, police, or public works department. Local officials are the best persons able to assess potential danger.
  • Inform affected neighbors. Your neighbors may not be aware of potential hazards. Advising them of a potential threat may help save lives. Help neighbors who may need assistance to evacuate.
  • Evacuate. Getting out of the path of a landslide or debris flow is your best protection.

Media and Community Education Ideas:

  • In an area prone to landslides, publish a special newspaper section with emergency

information on

landslides

and debris

flows. Localize the information by including the

phone numbers

of local

emergency

services offices, the Red Cross, and hospitals.

  • Report on what city and county governments are doing to reduce the possibility of landslides. Interview local officials about local land- use zoning regulations.
  • Interview local officials and major insurers. Find out if debris flow is covered by flood insurance policies and contact your local emergency management office to learn more about the program.
  • Work with local emergency services to prepare special reports for people with mobility impairments on what to do if evacuation is ordered.
  • Support your local government in efforts to develop and enforce land-use and building ordinances that regulate construction in areas susceptible to landslides and debris flows. Buildings should be located away from steep slopes, streams and rivers, intermittent- stream channels, and the mouths of mountain channels.

After the Landslide:

  • Stay away from the slide area. There may be danger of additional slides.
  •  Check for injured and trapped persons near the slide, without entering the direct slide area. Direct rescuers to their locations.
  • Help a neighbor who may require special assistance – infants, elderly people, and people with disabilities. Elderly people and people with disabilities may require additional assistance. People who care for them or who have large families may need additional assistance in emergency situations.
  • Listen to local radio or television stations for the latest emergency information.
  • Watch for flooding, which may occur after a landslide or debris flow. Floods sometimes follow landslides and debris flows because they may both be started by the same event.
  • Look for and report broken utility lines to appropriate authorities. Reporting potential hazards will get the utilities turned off as quickly as possible, preventing further hazard and injury.
  • Check the building foundation, chimney, and surrounding land for damage. Damage to foundations, chimneys, or surrounding land may help you assess the safety of the area.
  • Replant damaged ground as soon as possible since erosion caused by loss of ground cover can lead to flash flooding.
  • Seek the advice of a geotechnical expert for evaluating landslide hazards or designing corrective techniques to reduce landslide risk. A professional will be able to advise you of the best ways to prevent or reduce landslide risk, without creating further hazard.

Media and Community Education Ideas:

  • In an area prone to landslides, publish a special newspaper section with emergency information on landslides and debris flows. Localize the information by including the phone numbers of local emergency services offices, the American Red Cross chapter, and hospitals.
  • Report on what city and county governments are doing to reduce the possibility of

landslides.

Interview local

officials

about

local land-

use zoning

regulations.

 Interview

local officials and

major

insurers

regarding the

National Flood

Insurance

Program. Find out if debris flow is covered by flood insurance policies from the National Flood Insurance Program and contact your local emergency management office to learn more about the program.

  • Work with local emergency to prepare special reports for people with mobility impairments on what to do if evacuation is ordered.
  • Support your local government in efforts to develop and enforce land-use and building ordinances that regulate construction in areas susceptible to landslides and debris flows. Buildings should be located away from steep slopes, streams and rivers, intermittent- stream channels, and the mouths of mountain channels.

Before a Landslide: How to Plan:

  • Develop a Family Disaster Plan. Please see the “Family Disaster Plan” section for general family planning information. Develop landslide-specific planning.
  • Learn about landslide risk in your area. Contact local officials, state geological surveys or departments of natural resources, and university departments of geology. Landslides occur where they have before, and in identifiable hazard locations. Ask for information on landslides in your area, specific information on areas vulnerable to landslides, and request a professional referral for a very detailed site analysis of your property, and corrective measures you can take, if necessary.

If you are at risk from landslides:

  • Talk to your insurance agent.
  • Develop an evacuation plan.
  •  Discuss landslides and debris flow with your family. Everyone should know what to do in case all family members are not together. Discussing disaster ahead of time helps reduce fear and lets everyone know how to respond during a landslide or debris flow.
