Creeping Pütürge Segment with Geodetic Evidence

On January 24, 2020 the Mw 6.8 Sivrice (Elazığ) earthquake was arrested by the ~80 km long Pütürge segment. On February 6, 2023, the first earthquake of the Kahramanmaras Earthquake Sequence, also ended at the southwest end of this segment. Is it creep also that arrest 2023 Pazarcik rupture? We analyzed InSAR data over the Pütürge segment to answer this question. We used over 5000 ARIA standard product interferograms from two ascending and two descending tracks of the Sentinel-1 satellites and the MintPy software to produce InSAR time series and velocity maps for the area. Also we processed both survey and continuous GNSS data with GAMIT/GLOBK GNSS software (v10.7) from 2014. We analysed the results in three time periods – before, between, and after the two earthquakes. InSAR shows that before both earthquakes the segment was creeping and GNSS data is confirming that outcome. We also are searching for any unbroken part of this segment and if this could be another danger in the future. This work is supported by TUBITAK project numbers 114Y250, 118Y435 and 121Y400.
