The 2016 Kumamoto Earthquake: Crustal deformation around the faults
Crustal Deformation around the Faults Revealed by MAI analysis
Features of Crustal Deformation
A 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.
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.
