Description:
Hazardous ground deformation and landslides occur frequently in the Mila Basin,
Algeria and this problem remains unsolved. However, the historical seismicity in the
area indicates no severe damage from past earthquakes. For this reason, studies are
needed to monitor the slow ground movements and their triggering factors. Since
about two decades ago, satellite observations by interferometric synthetic aperture
radar (InSAR) technique and the multi-temporal
(MT-InSAR)
technique have provided
a tool for monitoring slow and extremely slow ground displacements. In this study,
2D decomposition of InSAR outputs revealed a sliding surface at two regions located
12 km apart, indicating slow motion rather than fast movement along the damaged
area. We concluded that the factors leading to surface displacement in the investigated
area include the triggering earthquakes, precipitation, terrain topography and
soil moisture. This study contributes to landslide hazard identification and risk assessment
in the Mila Basin.
