Copernicus Sentinels monitor Hawaii’s volcano
14 May 2018
Active for decades, Kīlauea volcano - on Hawaii's Big Island - erupted on 4 May. The island also experienced a magnitude 6.9 earthquake on the same day, forcing thousands to leave their homes.
On 30 April 2018, the floor of Puʻu ʻŌʻō crater, at Kīlauea Volcano, collapsed as magma drained from beneath the long-lived eruptive vent. Seismicity and ground deformation indicate that the magma moved eastward along the volcano's East Rift Zone and that is continuing to move into and erupt in the lower East Rift Zone.
Observations from the Sentinel satellites of the European Union's Copernicus Programme were used to monitor this event. Additional acquisitions from Sentinel-1 were planned, in particular to allow performing interferometry at shorter time intervals, using both Sentinel-1A and Sentinel-1B satellites.
The International Charter Space and Major Disasters was activated on 07 May by the US Geological Survey (USGS) on behalf of USGS Hawaii Volcano Observatory.
