Sentinel Interferogram of the 2016 seismic events in Kyushu Island, Japan

Operational capabilities developed in the context of BEYOND Center of Excellence project (http://beyond-eocenter.eu/) for EO based monitoring of natural disasters enable the rapid assessment of ground deformation field due to geo-hazards.
On the 14th of April 2016 15:03:46 (UTC) an earthquake struck the island of Kyushu in Japan (Mw 6.0). This event was followed by a larger one (Mw 7.0) on the 15th of April 2016 16:25:06 (UTC). Both seismic events took place close to the city of Kumamoto and had about the same centroid depth (~12km).
The earthquakes caused landslides and affected sites of cultural heritage. More than 2,800 injuries and over 48 fatalities have been reported so far. Several buildings were heavily damaged or even completely destroyed.
BEYOND acquired a set of Sentinel-1 TOPSAR Images from the ascending mode. An image over the inflicted area was acquired on the 8th of April 2016 and a second one on the 20th of April 2016. The differential Interferogram depicts the ground deformation on the surface due to the two events. In the map each fringe corresponds to 2.8 cm motion along the Line-Of-Site (LOS) of the satellite. BEYOND Center of Excellence is watching over the phenomenon using continuous acquisitions of satellite data.
