Observation Results of ALOS/PALSAR Relating to the Magnitude 8.8 Earthquake in Chile, 2010 (1)
On February 27, 2010 (UTC), a magnitude 8.8 earthquake occurred off the coast of middle Chile, in the South America. The Japan Aerospace Exploration Agency (JAXA) performed an emergency observation on March 2 using the Phased Array Type L-band Synthetic Aperture Radar (PALSAR) installed on the Advanced Land Observing Satellite (ALOS) to determine the state of damage caused by the earthquake. In this report, we conducted differential interferometric SAR (DInSAR) analysis to detect crustal deformation associated with the earthquake using the data acquired on January 15, 2010.The blue rectangle indicates observation areas shown in Figure 2, and the red star represents the epicenter.
JAXA plans to continue ALOS observations of the afflicted area in Chile.
