Scientific and Societal Legacies of Volcanic Eruptions
Session ID#: 82243
Session Description:
Some volcanic eruptions have fundamentally changed our understanding of how volcanoes work, how landscapes evolve, how ecosystems are affected and adapt, and how hazardous phenomena affect human populations. For example, the 18 May 1980 eruption of Mount St. Helens not only highlighted the poorly known phenomena of debris avalanches and lateral blasts, but also advanced scientific thought in diverse disciplines including volcanology and geophysics, atmospheric sciences, ecology, hydrology, geohealth, hazards, communication, and social sciences. Some four decades later, the legacy of that eruption continues to affect and influence both science and society. This session highlights scientific and societal legacies of eruptions (Mount St. Helens and others) over the past few decades. We invite contributions from diverse disciplines that demonstrate how a particular eruption has fostered critical basic and applied research that affects our ability to understand and mitigate volcanic activity.
