Abstract

Satellite-derived data, including an estimation of the eruption rate, proximal volcanic deposits, lava flow morphometric parameters (area, maximum length, thickness, and volume) are here provided for the eruptions occurred at Mt Etna between January 2011 and December 2015. These eruptions took place at the New Southeast Crater (NSEC), the youngest of the summit craters of Etna. The time-series analysis of multispectral SEVIRI images(timeresolution of 15 min)provided an estimation of event magnitude and intensity of the effusive material erupted during effusive events, while tri-stereo Pleiades images (spatial resolution of 50 cm) gave the pre-emptive topography and the topographic changes due to the volcanic deposits. The level of accuracy of these estimates suggests that the integration of multiplatform remote sensing products represents a new potential of merging capabilities to enable a more comprehensive response to effusive crises.
