On January 07, 2022, 17:45:31 UTC a strong earthquake of M6.2 occurred in Northern Qinghai, China. geObservatory service of BEYOND Center of Earth Observation Research and Satellite Remote Sensing of the National Observatory of Athens, was activated and detected co-seismic deformation induced by the seismic event. The first co-seismic interferogram, was generated from Sentinel-1 SLC images of descending track 33, of December 29, 2021 and January 10, 2022. Each fringe in the interferogram corresponds to ground deformation equal to 2.8 cm. All co-seismic and pre-seismic interferograms, associated with the event are freely available in the geObsevatory website (http://geobservatory.beyond-eocenter.eu/), which is updated with new interferograms as long as new Sentinel-1 satellite data becomes available at the Hellenic Mirror Site.
