Space Geodetic Views on the 2021 Central Greece Earthquake Sequence: 2D Deformation Maps Decomposed From Multi-Track and Multi-Temporal Sentinel-1 InSAR Data

Pioneering efforts well studied the deformation decomposition of single earthquake using a pair ascending (ASC) and descending (DES) track InSAR data. However, sequent events is rarely discussed hard to implement. That's because it's ensure deformations related each can be recorded by ASC DES Three earthquakes (Mw>5.5) just hit Central Greece in March 2021, this sequence provides us with perfect case study 2D (East-West Up-Down) when mentioned premise cannot satisfied. In context, we proposed Multi-track Multi-temporal (MTMT2D) method. Its novelty behind rationale are decompose event through fusing multi-track multi-temporal interferograms. Based on decomposed deformations, invert slip distribution three respectively. We found that better constrain fault geometry than interferogram. Furthermore, our geodetic inversion results also suggest domino-like triggering rupture process for sequence. It indicates MTMT2D method potentially reveal more details about
