Volcanic hazards and risk lie at the heart of global geoscience, with about 800 million people threatened by eruptions and other related phenomena. Volcanoes strongly affect humans and the environment through submarine explosions, tephra fallout, pyroclastic flows, earthquakes, tsunamis, and ocean acidification. Evaluation of the impact of volcanic activity on a given region mostly relies on the reconstruction of the eruptive history of volcanoes through the identification, correlation and dating of tephra layers preserved in terrestrial and marine depositional records. In addition, more recent interdisciplinary studies are being used to deepen our understanding of the formation and destruction of volcanoes and the accompanying mass transport processes, as they might significantly contribute to the volcanic hazard assessment. This session will focus on different approaches for reconstructing the history, processes, and evolution of volcanic regions. We invite contributions from all related scientific fields to derive a more comprehensive perspective on the past and present impact of volcanic eruptions, and their potential impacts on the environment and surrounding populations.
Please keep the cameras on. If you only have a microphone with no contact to the audience, it's no fun to present.
Also: Just like during the previous In Presence meetings, most of the participants have a tight schedule. Please keep strictly to the 2 or 5 minute limit!
