2 de Junho, 18:00h: Explosive volcanism in field and lab
Doctor Ulrich Kueppers, from Ludwig-Maximilians-
Abstract: Volcanic eruptions are the surficial expression of magma migration in Earth’s crust. Despite substantial technological advances and growing monitoring networks, our understanding of the underlying processes and parameters driving explosive eruptions is far from complete. Modern volcanology is developing away from a classical backward-looking geology discipline and aims at a more holistic approach including a better precision on eruption onset, type and duration.
Unlike in meteorology, magmatic processes bare direct observability. Eruption characteristics carry detailed information about the underlying processes and have developed into a new source of information that will increase our understanding of volcanic eruptions. Two routes have emerged in the past years:
1) high-resolution and high-frequency recording of explosive eruptions and scaled laboratory experiments.
2) increasingly reliable unoccupied aerial systems (UAS) that allow for close-up observation of eruptive phenomena and sensor deployment.
Implementation of the related results with existing yet continuously evolving geological, geophysical and remote sensing data sets will contribute to develop volcanology towards an increasingly sophisticated science that will learn to predict and be prepared and not only react and respond promptly.
