Datasets description

  On September 5, 2022, at 12:52, a magnitude 6.8 earthquake occurred in Luding County, Ganzi Prefecture, Sichuan Province (29.59°N, 102.08°E) at a depth of 16 km. Based on the 200km range of the epicenter, we provide the pre-disaster sentinel-1_SLC lifting orbit radar data products and the post-disaster sentinel-1_SLC-HD lifting orbit radar data products.

Data source description

  Data source: https://search.asf.alaska.edu/#/.

Data processing method

  A first-order product that has been processed to obtain phase and amplitude information. The phase information is a function of time, and based on the phase information and velocity a distance measurement can be realized (which can be used for ranging and deformation observation).

Data quality description

  The data quality is good.
