Multi-sensor satellite-based monitoring of a volcanic eruption
This paper presents a combined analysis of multi-sensor satellite-based remote sensing data monitoring of a volcanic eruption – the 2014/15 Holuhraun fissure eruption in Iceland. Signalized by increasing seismic activity on 16 August 2014 onwards, a dike originated from the Bardarbunga Volcano broke...
