Crustal Deformation Studies using Synthetic Aperture Interferometry

Abstract

Satellite based Synthetic Aperture Radar interferometry (InSAR) is a well known remote sensing technique to generate
digital elevation models of meter-scale accuracy. The technique also enables to measure ground deformation with subcentimeter
level accuracy at a spatial resolution of few meters covering on large areas. In this article we review recent studies
from India on crustal deformation related to earthquakes using InSAR technique. We also briefly discuss limitations and
recent technological advances of this technique with a future perspective.
