Specific Sentinel-1B observations have been planned to support the analysis of the two earthquakes that occurred in China on 08 August (in central China on 8 August at 13.19 UTC, and in north-western China close to the border with Kazakhstan on 08 August at 23.47 UTC), and possible aftershocks.

With the Sentinel-1A acquisitions already planned, these additional Sentinel-1B acquisitions will allow to generate interferograms at 6 days for the month of August, in both ascending and descending geometry.
