1-1-1-1-1-1-1-1-1-1-1-1-1-1 From: Lucia Pappalardo <lucia.pappalardo@xxxxxxx> Dear Colleagues, We would like to invite you to join us at the Rittmann 2024 Conference in Catania, scheduled for September 18-20, 2024. We are excited to bring to your attention *Session S15: "Linking Surface Observables to Sub-Volcanic Plumbing Systems at Active Calderas"*, dedicated to analyzing caldera unrest through multi- and interdisciplinary approaches, with a particular focus on the latest research related to the *Campi Flegrei caldera.* https://www.conferenzarittmann.it/sessioni/sessioni/56-s20-the-manifold-interaction-between- <http://goog_1484867782> humans-and-volcanoes-interdisciplinary-studies-around-volcanology.html <http://humans-and-volcanoes-interdisciplinary-studies-around-volcanology.htmll> Below is an overview of the session. The deadline for abstract submission is May 17, 2024. Session S15: Linking Surface Observables to Sub-Volcanic Plumbing Systems at Active Calderas Large calderas are responsible for some of the most catastrophic eruptions on Earth. These systems often undergo prolonged periods of unrest, characterized by ground deformation, seismicity, gravity changes, and degassing, which may or may not lead to an eruption. It is challenging to determine whether unrest results from magma transfer, hydrothermal system changes, tectonic processes, or a combination of these factors, even at well-studied and closely monitored volcanoes. Despite advances in monitoring technology, linking observed signals to magma movement from deep reservoirs to the surface remains complex. Consequently, it is crucial to develop multidisciplinary approaches to thoroughly investigate and monitor volcano conditions. This is essential for providing timely interpretation of monitoring data during periods of unrest. A key focus is the densely populated Campi Flegrei caldera, which has experienced unrest over the past seven decades, recently attracting national and international attention due to seismicity associated with the ongoing unrest. This session aims to gather scientists from various disciplines, including stratigraphy, igneous petrology, geochemistry, structural geology, geodesy, geophysics, laboratory experiments, and numerical modeling. We strongly encourage interdisciplinary contributions to gain a comprehensive understanding of active calderas like Campi Flegrei and others worldwide. We hope you will consider submitting an abstract and look forward to your participation in this engaging session. Kind regards, Lucia Pappalardo, Anna Tramelli, Elisa Trasatti, and Stefano Caliro 1-1-1-1-1-1-1-1-1-1-1-1-1-1 ------------------------------
