The 2016 Kumamoto Earthquake: Crustal deformation around the faults
Crustal Deformation around the Faults Revealed by MAI analysisReleased: Apr. 28, 2016 Japanese version of this page
Features of Crustal DeformationA large earthquake (M7.3) occurred in Kumamoto, Japan on April 16, 2016. We applied MAI (Multiple Aperture Interferometry) analysis using ALOS-2/PALSAR-2 data, and revealed the crustal deformation around the faults which the standard InSAR technique could not detect.
NOTE: The MAI technique is still under investigation, and this is a preliminary result. The result is possibly updated with further elaborated analyses. [PNG: 1.33MB] Figure 1. Blue and red areas represent forward (almost southward) and backward (almost northward) horizontal deformation of the flight direction. * We also confirmed that the result of the pixel offset method showed a corresponding crustal deformation.
