Assessments of land subsidence in the Gippsland Basin of Australia using ALOS PALSAR data

The standard deviation of difference between the InSAR results and the ground survey data is approximately 4 mm/year near the coastal area and 15 mm/year near the mining sites. Several rapidly deforming areas have been identified at the mining sites and the surrounding areas. Deformation rate at up to − 82.9 mm/year is observed in these areas. The deformation at the mining sites and the surrounding areas are expected to be resulted from mining activities and associated mine dewatering. Moreover, several minor displacement zones have been observed and investigated in the area between the Loy Yang Mines and the Gippsland coast as well as the area between Yanakie and Wilsons Promontory.
