| Abstract: | InSAR is a 3-D imaging technique from the space to the earth.It indicates that remote sensing has stepped into a new stage from acquiring 2-D to 3-D information,and also brings a revolution in geodesy.InSAR is a full new tool in the geohazards research.The micro-displacement monitoring using InSAR and D-InSAR technique is a new method and paid highly attention.The paper gives some examples of InSAR application on geohazards such as earthquake,volcano eruption and landslides etc.it shows that InSAR has a great potential and advantage in deformation monitoring research. |
