Identification of landslides in La Reunion Island with JERS-1 and RADARSAT-1 radar interferometry
نویسنده
چکیده
La Réunion Island is affected by constant slope movement and huge landslides due to the rough topography, a wet climate and favourable geological context. Radar interferometry can provide a mean for identifying landslides on a large scale. Because of the vegetation cover, C-band interferograms are generally hampered. Using JERS-1 images, we show that the L-Band can be used to overcome the loss of coherence observed in the C-band. The technique has been applied to the cases of the Grand Ilet and Hellbourg landslides located in Salazie Circle.

Observation of a Large Landslide on La Reunion Island Using Differential Sar Interferometry (JERS and Radarsat) and Correlation of Optical (Spot5 and Aerial) Images
Slope instabilities are one of the most important geo-hazards in terms of socio-economic costs. The island of La Réunion (Indian Ocean) is affected by constant slope movements and huge landslides due to a combination of rough topography, wet tropical climate and its specific geological context. We show that remote sensing techniques (Differential SAR Interferometry and correlation of optical im...
متن کاملDual-band Radar Interferometry
This paper demonstrates the feasibility of using differential interferometric synthetic aperture radar (DInSAR) for subsidence monitoring over the underground mining sites in New South Wales, Australia. The SAR data acquired in dual-frequency, Cand L-band, of microwave portion of electromagnetic spectrum by ERS-1/2, Radarsat-1 and JERS-1 satellites have been examined. The issues of decorrelatio...
متن کاملRadar Interferometry and Its Application to Changes in the Earth's Surface
Geophysical applications of radar interferometry to measure changes in the Earth's surface have exploded in the early 1990s. This new geodetic technique calculates the interference pattern caused by the difference in phase between two images acquired by a spaceborne synthetic aperture radar at two distinct times. The resulting interferogram is a contour map of the change in distance between the...
متن کاملSurface deformation associated with the March 1996 earthquake swarm at Akutan Island, Alaska, revealed by C-band ERS and L-band JERS radar interferometry
In March 1996, an intense earthquake swarm beneath Akutan Island, Alaska, was accompanied by extensive ground cracking but no eruption of Akutan volcano. Radar interferograms produced from L-band JERS-1 and C-band ERS1/2 images show uplift associated with the swarm by as much as 60 cm on the western part of the island. The JERS-1 interferogram has greater coherence, especially in areas with loo...
متن کاملApplication of Repeat-pass DInSAR and GIS for Underground Mine Subsidence Monitoring
This research used both ERS and JERS-1 images to investigate the feasibility of differential radar interferometry (DInSAR) for mine subsidence monitoring in the state of New South Wales, Australia. DInSAR results are analysed and validated with the aid of Geographic Information System (GIS) tools. The drawbacks of using interferometric measurements for mine subsidence monitoring are discussed. ...
