BE PREPARED FOR A

LANDSLIDE

Landslides cause 25-50 deaths and more than a billion dollars in damage each year.

A landslide is rocks, earth, or other materials moving down a slope. A mudflow is a landslide that is combined with up to 60 percent water.

Can strike with little or no warning

Travel 55-110 miles per hour

Caused by rain, earthquakes, volcanoes, or changes to the land

Earthquake

Can result from flooding

IF YOU ARE UNDER A LANDSLIDE WARNING, FIND SAFE SHELTER RIGHT AWAY

  • Hurricane

    Evacuate early to avoid landslides risk.

  • Hurricane

    Listen for emergency information and alerts.

  • Hurricane

    Watch for signs of landslide.

  • Hurricane

    Watch for flooding.

Hazard Scope and Impact

Debris flow causes a multitude of damages to local infrastructure, including roads and residences.

Death and Injuries Impact

Related studies from volcano activity rock and mudflows identified asphyxiation, trauma, and shock as primary causes of fatalities. Floodwaters associated with landslides also posed a high risk for fatality. The critical related causes of deaths and injuries identified for landslides included insufficient risk identification, lack of communication, and no official warning.

Effective Protective Action Timeframes

For fast landslides, advance professional review to avoid construction in hazard risk areas and monitoring of conditions of slopes to evacuate well in advance are identified as the most effective. Once a fast slide starts, “last resort” actions are very dependent on the size of the landslide and your location relative to the slide path.
