Using PS-InSAR to detect surface deformation in geothermal areas of West Java in Indonesia [PDF]

, 2018
In this paper, the Persistent Scatterer InSAR (PS-InSAR) technique is applied in order to investigate the ground deformation in and around two geothermal areas in West Java, Indonesia. Two time-series of ALOS PALSAR and Sentinel-1A acquisitions, covering

PS-InSAR derived deformation study in the Kachchh, Western India

Applied Computing and Geosciences, 2020
The accumulation of crustal strain towards the western part of India, especially in the Kachchh Rift basin, is making one of the most seismically active parts of the Indian plate. Several strong to major earthquakes, including the recent 2001 (M7.7) Bhuj earthquake, were triggered in the Kachchh rift basin during the last two centuries.

Integration of PS-InSAR and GPS for monitoring seasonal and long-term peatland surface fluctuations

, 2010
Due to water table elevation changes and entrapped gas ebullition, vertical fluctuations in peatlands surface of up to 20 cm have been reported. Combined with GPS measurement, persistent scatterers synthetic aperture radar interferometry (PS-InSAR) has ...

A First Approach for Displacement Analysis in Lisbon Downtown Using PS-InSAR

Procedia Technology, 2014
AbstractLisbon Downtown presents unique geomorphologic properties which makes it an area prone to terrain instability. Serious accidents have occurred there, namely, during the 1755 earthquake and a flooding event at the extension of a subway line, demanding a frequent monitorization for safety reasons and expense minimization. In this study, Permanent

Monitoring Land Subsidence Using PS-InSAR Technique in Rawalpindi and Islamabad, Pakistan

Remote Sensing, 2022
Land subsidence is a major concern in vastly growing metropolitans worldwide. The most serious risks in this scenario are linked to groundwater extraction and urban development. Pakistan’s fourth-largest city, Rawalpindi, and its twin Islamabad, located at the northern edge of the Potwar Plateau, are witnessing extensive urban expansion.
