Observation results of offset tracking. Range offset and azimuth offset derived from descending track 23 (a, b), ascending track 130 (c, d), descending track 29 (e, f). Black lines traced geological active fault traces by Nakata and Imaizumi (2002). Red triangle is the location of Mt. Aso. Signals of range offset mean the displacement between the SAR satellite and observation area, and that of azimuth offset means the horizontal displacement in the direction of satellite flight. Positive signals of range offset and azimuth offset indicate the displacement away from the SAR satellite and toward the satellite flight direction, respectively. The terms of F1-3 indicate the locations of the fault segments in our fault model (Fig. 6)
