Assessment Of Ground Deformations Using Insar Techniques And Shallow Subsurface Imaging In Pulau Pinang, Malaysia

Ground deformation presents a significant threat to people's lives and properties in Pulau Pinang, Malaysia. It usually occurs when there is continuous heavy rainfall. Previous methods on this hazard were based on simulation, modelling, and geo-engineering issues. Still, none of them quantified...
