ALOS-2/PALSAR-2 Observation Results of Mt. Shindake Volcano,
Kuchinoerabu-jima Island

The Japan Aerospace Exploration Agency (JAXA) observed Mt. Shindake volcano, Kuchinoerabu-jima Island with the Advanced Land Observing Satellite-2 "DAICHI-2" (ALOS-2)/ the Phased Array Type L-band Synthetic Aperture Radar type 2 (PALSAR-2) on August 7 0:38(JST).
Figure 1 shows the observation area of PALSAR-2 (Red frame) and the orbital path of ALOS-2 (Blue line).

Figure 3 shows the ALOS-2/PALSAR-2 image (Off-nadir angle 53.3 deg.) and ALOS/PALSAR image observed in Sep. 17, 2006 (Off-nadir angle 41.5 deg.).
Both images are orthorectified. Circled part is the Mt. Shindake that erupted.

JAXA has provided those observed PALSAR-2 images to the municipal agencies. JAXA will continue the observation and analysis at this area.
