In the second Geohazards challenge BETTER exploits Sentinel-1 interferograms generated systematically by the German Space Agency (DLR) to study co-seismic deformation effects. Data defining the temporal range of interest and earthquake event coordinates is selected and filtered. A web-interface provides tools to measure characteristics such as amplitude and extension of the deforming area and identification of fault traces.


Overview of the earthquake events analyzed in this pilot study. Areas in purple approximate the Global Tectonic Area (GTA) as defined by the CEOS WG Disasters, where systematic processing of Sentinel-1 SAR data is performed in the framework of the ESA TEP  Geohazards project. Circles are the earthquakes considered in this preliminary phase of analysis, spanning the period June 2017 - December 2018.

This information can be used for visual data mining and to derive statistical indicators. Moreover, results of this challenge are useful for the calibration of machine learning algorithms based on extensive EO datasets, as well as for scientific studies aimed at evaluating seismic hazard.
