Satellite observations of the April 1993 eruption of Lascar volcano
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.
