“…Both ascending and descending tracks ALOS‐2 L‐band SAR images, acquired in the strip‐map mode, were processed using the GMTSAR software with a multilook factor of 32 × 12 (azimuth multifactor × range multilook factor) to maintain the interferometric correlation in the near‐fault zone (Sandwell et al, ; Yang et al, ). The SRTM‐4 digital elevation model was used to remove the topographic contribution from the initial interferogram.…”

Coseismic surface deformation imaged through interferometric synthetic aperture radar (InSAR) measurements was used to estimate the fault geometry and slip distribution of the 2017 Mw 6.5 Ormoc earthquake along a creeping segment of the Philippine Fault on Leyte Island. Our best fitting faulting model suggests that the coseismic rupture occurred on a fault plane with high dip angle of 78.5° and strike angle of 325.8°, and the estimated maximum fault slip of 2.3 m is located at 6.5 km east‐northeast of the town of Kananga. The recognized insignificant slip in the Tongonan geothermal field zone implies that the plastic behavior caused by high geothermal gradient underneath the Tongonan geothermal field could prevent the coseismic failure in heated rock mass in this zone. The predicted Coulomb failure stress change shows that a significant positive Coulomb failure stress change occurred along the SE segment of central Philippine Fault with insignificant coseismic slip and infrequent aftershocks, which suggests an increasing risk for future seismic hazard.
