Lineaments 
4. LANDSLIDES 
Slope-instabilities developed in the 
superficial quaternary deposits and terti- 
ery sediments during the 16.11.1911-event 
demonstrated the existence of potentially 
hazardous secondary effects of earthqua- 
kes. Various types of  landslides are 
common in parts of SW-Germany as for 
example in the northwestern part of the 
Lake Constance area. There landslides 
occur after nearly every wet season of the 
year. The detailed interpretation of 
satellite radar and of LANDSAT TM-data, 
as well as of aerial photographs 
allows the detection of lineaments that 
are coincident with fault and fracture 
systems influencing slope  instabilties. 
Thus, lineament analysis contributes to 
landslide hazard zoning. .and.. to ‚the 
location of areas susceptible to slope 
failure. This is of fundamental value 
for planning purposes. 
Satellite radar data from Southwest- Ger- 
many have demonstrated their value as a 
tool for earthquake damage-risk evalua- 
tion.
