Postseismic Ground Displacements Following The 2023 Kahramanmaraş Earthquakes

Satellite radar interferometry (InSAR) data captures three-dimensional ground movement for approximately two years after the 2023 Kahramanmaraş earthquakes. The dataset contains temporal 3D postseismic displacement measurements from February 2023 to December 2024. It was created by researcher Sigurjon Jonsson and published on figshare.

Use Cases

• Model afterslip and viscoelastic relaxation by analyzing temporal 3D displacement vectors across the fault zone.
• Calibrate crustal rheology models using the two-year time series of postseismic ground motion.
• Validate satellite-derived displacement products by comparing InSAR time-series results with independent geodetic data.
• Assess continued seismic hazard by mapping the spatial extent and decay rate of post-earthquake displacements.

Strengths

• Covers a two-year postseismic observation period from February 2023 to December 2024.
• Provides three-dimensional displacement vectors derived from InSAR data.
• Focuses on a major seismic sequence with significant global scientific interest.

Limitations

• Specific row count, spatial resolution, and measurement uncertainty metrics are not provided.
• Data is packaged in a 3.7 GB ZIP file without documented internal structure or sample data.
• Geographic coverage is limited to the region affected by the 2023 Kahramanmaraş earthquakes.
