2.1 Landslide Risk
Landslides are events where material such as rock and earth moves down a slope, often with very destructive force. Landslides are driven by gravity and important contributing factors include slope stability and water content. They are often triggered by heavy rainfall and/or runoff and are more common in areas where the vegetation providing stability and reducing the speed of runoff has been degraded.
Interpretation:
The maps below show the distribution of landslide hazard across the country and categorize the hazard into five levels (very high, high, medium, low and no-data). It shows that the eastern half of the country has almost all the areas of “very high” and “high” landslide hazard, based on the available data. The second map shows how one of the hazard layers within DRMInfo can be combined with one or more of the layers representing elements-at-risk. In the map “Houses at Landslide Risk Timor-Leste”, landslide hazard has been combined with the national household
location data. Only households that sit within the boundaries of the “very high” and “high” landslide hazard regions are depicted on this map.
