ALOS-2 ScanSAR RGB Change Map

Three PALSAR-2 ScanSAR images were used for disaster response:

Pre-seismic: 2025.01.16 & 2025.02.19

Co-seismic: 2025.03.30

Orbit and angle: Descending, 39.02 degree

Normalized pre-seismic coherence – co-seismic coherence represents “red” channel.

Normalized co-seismic coherence – pre-seismic coherence represents “green” channel.

Averaged pre-seismic and co-seismic coherence represents “blue” channel.
