The largest historic eruption of the Lascar volcano, Chile, occurred during April 1993. The eruption lasted two days, producing pyroclastic flows, covering an 18.5km2 area, and a major ash plume, leading to widespread ashfall. Here we demonstrate how combined observations from the Japanese Earth Observation (JERS-1) and the National Oceanographic and Atmospheric Administration (NOAA) satellites were used to document this eruption. These two satellite platforms provide complementary data, giving high resolution spatial (JERS-1), spectral (JERS-1) and temporal information (NOAA). Such an integrated remote sensing approach offers a valuable means of easily and safely monitoring large, dangerous, volcanic eruptions and post eruption processes.
