11.11. Slope Stability and Landslide Monitoring

Try these first

1. 1.

   What does DEM stand for?

   Hint

   Think about what 'Digital Elevation Model' represents.

2. 2.

   What is the purpose of a slope map?

   Hint

   Consider why steep areas may be dangerous.

3. 3.

   What is the primary purpose of using Digital Elevation Models (DEMs) in slope stability?

   • To create topographical maps
   • To monitor vegetation
   • To identify unstable zones
   • To measure rainfall

   Hint

   Think about the main outcome of analyzing terrain in geoinformatics.

4. 4.

   True or False: Time-series imagery is only taken once to monitor for landslides.

   • True
   • False

   Hint

   What does 'time-series' suggest about the data?

5. 5.

   Analyze a provided DEM of a region and identify areas that are at high risk of landslides. List the factors contributing to this risk.

   Hint

   What features in the DEM indicate potential instability?

6. 6.

   Create a report on how an early warning system could be improved by integrating real-time data from time-series satellite images.

   Hint

   Consider what timely information could be critical for response measures.
