Fukushima Hamadori, Japan Earthquake (M7.0): Crustal deformation detected by ALOS/PALSAR data
Crustal Deformation Observed by Synthetic Aperture Radar (SAR)

Crustal Deformation by InSAR
A M=7.0 (JMA) earthquake occurred in Fukushima Hamadori Region, Japan on April 11, 2011 (UTC). An interferometric analysis of the data acquired by the Phased Array type L-band Synthetic Aperture Radar (PALSAR) onboard the Advanced Land Observing Satellite (ALOS) allows us to clarify spatial distribution of surface deformation associated with the earthquake.
The interferogram shows clear displacement discontinuities along Idosawa fault and Yunotake fault.
