A Study of Detection of Landslide Disasters due to the Pakistan Earthquake using ALOS data
On October 29, 2008, magnitude 6.4 earthquake occurred in a area of western Pakistan. One of the Japanese earth observation satellite, Advanced Land Observing Satellite (ALOS), observed this area by all onboard sensors, AVNIR-2, PRISM, and PALSAR. By optical imagery, AVNIR-2 and PRISM imagery, huge landslide (rock slide) and landslide dam were confirmed by visual interpretation. And also this l...
متن کاملDetection of Co - and Postseismic Displacements from Large Earthquakes with Alos / Palsar
We have been studying coand postseismic displacements from large earthquakes since mid-2006, using ALOS PALSAR images acquired before and after these events. Due to its wavelength, coherence is high even in heavily vegetated areas or steep ranges. We can estimate slip distribution of these earthquakes based on the observed interferograms using a nonlinear inversion scheme. So far, we could not ...
متن کاملPreliminary Results of Satellite Radar Differential Interferometry for the Co-seismic Deformation of the 12 May 2008 Ms8.0 Wenchuan Earthquake
1082-4006/08/14(01)-12$5.00 ©2008 The International Association of Chinese Professionals in Geographic Information Science (CPGIS) Abstract Satellite differential SAR interferometry has been widely accepted as a powerful tool to map co-, postand inter-seismic deformation since its successful application to the 1992 Landers Earthquake. As soon as the Ms8.0 Wenchuan Earthquake occurred on 12 May ...
متن کاملThe Penetration Depth Derived from the Synthesis of ALOS/PALSAR InSAR Data and ASTER GDEM for the Mapping of Forest Biomass
The Global Digital Elevation Model produced from stereo images of Advanced Spaceborne Thermal Emission and Reflection Radiometer data (ASTER GDEM) covers land surfaces between latitudes of 83°N and 83°S. The Phased Array type L-band Synthetic Aperture Radar (PALSAR) onboard Advanced Land Observing Satellite (ALOS) collected many SAR images since it was launched on 24 January 2006. The combinati...
متن کاملSAR interferometry using ALOS-2 PALSAR-2 data for the Mw 7.8 Gorkha, Nepal earthquake
The Advanced Land Observing Satellite-2 (ALOS-2, “DAICHI-2”) has been observing Nepal with the Phased Array type L-band Synthetic Aperture Radar-2 (PALSAR-2) in response to an emergency request from Sentinel Asia related to the Mw 7.8 Gorkha earthquake on April 25, 2015. PALSAR-2 successfully detected not only avalanches and local crustal displacements but also continental-scale deformation. Es...
