SAR images around the Shinmoe-dake crater observed from January 18, 2011, to March 29. Detailed information for each image is given in Table 1. These were described in radar coordinates. Although the aspect ratios of these images were adjusted so that the ground-range and azimuth resolutions roughly correspond, the areas of the images are not exactly the same due to foreshortening distortion. Red arrows indicate along-track (T) and range (R) directions.
