Visualizing the Aftermath of Volcanic Eruptions

Volcanic eruptions are not only hazardous in the vicinity of a volcano, but also affect the climate and air travel at larger distance. In this paper, we present our results on the 2014 IEEE Scientific Visualization Contest, which centers around the fusion of multiple satellite data modalities to reconstruct and assess the movement of ash clouds. In particular, we shed light on the Grı́msvötn, PuyehueCordón Caulle and Nabro eruptions in 2011. We study the agreement of the satellite data, reconstruct the ash clouds, visualize endangered flight routes, minimize occlusion of particle trajectories and finally focus on the pathways of aerosol into the stratosphere.
