Network coverage

Visually monitoring the susceptibility of hundreds of km of road network to geohazards such as slope instability is slow, expensive, subjective and potentially dangerous.

In a pilot study of the Cyprus road network using InSAR analysis, a number of geohazards were pinpointed quickly and objectively. This included at Petra tou Romiou where repeated pavement resurfacing failed to solve a road cracking problem. InSAR identified the larger scale mass movements causing the cracking which led to measures being taken for a more permanent solution.

Highlight

• Network-wide visual geohazard susceptibility surveys are slow, subjective and potentially dangerous. 

• A network-wide InSAR analysis and landslide susceptibility mapping in GIS quickly pinpointed the most susceptible locations. 

• Greater insight was gained at one location of repeated pavement resurfacing that led to a more permanent solution.
