Report a Landslide

OMB No. 1028-0100
Expires: 12/31/2014

USGS scientists may use some of the information that you enter in qualitative descriptions of damage in USGS publications. You would be identified as “an observer” and your location would be given in general terms. Parts of some first-person accounts may be reproduced as quotations in USGS publications. Note, we strive to respond to all requests for landslide information, but we are not able to respond to all reports.

Landslide Summary

Location

Landslide Type Hover your mouse over each option for additional information, or see:
USGS Fact Sheet - Landslide Types and Processes http://pubs.usgs.gov/fs/2004/3072/
  • fall landslide diagram fall landslide photo
    • A fall occurs when a mass of any size detaches from a steep slope or cliff and descends mostly through the air by freefall, bouncing, or rolling.
  • flow landslide diagram flow landslide photo
    • In a flow, distributed (fluid-like) movement of a mass of rock or soil may proceed slowly or swiftly. Flows of mud and debris commonly resemble rivers of rapidly moving wet concrete.
  • topple landslide diagram topple landslide photo
    • A topple consists of the forward rotation or tilting of a column of rock or soil.
  • rotational landslide diagram rotational landslide photo rotational landslide photo
    • In rotational sliding, movement is along a spoon-shaped or cylindrical surface so that movement at the top (head) of the slide appears to be mostly downward and the ground surface at the head may tilt backward, into the hillside.
  • translational landslide diagram translational landslide photo translational landslide photo
    • In translational sliding, movement occurs along a more or less planar surface that commonly is almost parallel to the hillside.
  • spread landslide diagram spread landslide photo
    • In a spread, lateral movement causes the ground to pull apart, with resulting formation of a series of more or less parallel fractures. Spreading may occur on gentle slopes.
  • avalanche landslide diagram avalanche landslide photo
    • An avalanche is an extremely rapid flow-like or sheet-like movement of a large, crumbling mass of rock down a steep mountainside or over a cliff.

The remainder of this report is optional.
