1-1-1-1-1-1-1-1-1-1-1-1-1-1 From: Federico Di Traglia <ditragliafederico@xxxxxxxxx> Dear colleagues, we would like to invite you to submit an abstract to the session "NH2.4 Co-organized by GM9 - Slope instabilities in onshore and offshore volcanic environments" at EGU General Assembly (23-28 April 2023, Vienna, Austria & Online). Deadline for abstract submissions: 10 January 2023 Subaerial and underwater slope instabilities in volcanic environments vary from slow and continuous to sudden and catastrophic. They can range from shallow debris remobilizations manifesting as rockfalls or debris flows, to large lateral collapses, which can remobilize up to hundreds of cubic kilometers of material. These events and their interconnected effects can extend to the volcano periphery, affecting areas and populations far from the volcanic center. This is the case for rock or debris avalanches and lahars that can devastate vast areas, resulting in fatalities, damage, and changes to the landscape or for sudden flank failures in island, coastal, or submarine volcanoes where a tsunamis can be generated that can reach coastal areas tens of kilometers away from the source. Larger events are low in frequency but high in intensity which make them difficult to study and can result in significant local and regional hazards, often with catastrophic consequences. In volcanic areas slope instability is influenced by the complex interactions between tectonics, magmatic fluids, meteorological conditions, material alteration, eruptive events, and gravitational processes, this can lead to significant changes in flow rheology along the slope and to complicated cascading processes which are challenging to understand and predict. As a consequence, successful strategies for hazard assessments related to slope instability in volcanic environments need to involve integrated methodologies for detection, mapping, monitoring, and modeling that are able to capture their complex nature. This session encourages multidisciplinary contributions that integrate onshore and offshore investigations, field-based geological studies, geomorphological mapping, volcanic rocks and deposits characterization, seismic and geodetic monitoring, geophysical investigations, remote sensing, and analytical, numerical and experimental modeling to tackle the challenging and fascinating study of these processes. https://urldefense.com/v3/__https://meetingorganizer.copernicus.org/EGU23/session/45056__;!!IKRxdwAv5BmarQ!bBAmOhPloMN00FhPyHK4SBwU1pHtQbLU30kjtVQdFbbo5IZ3qO4ZUmn3juU87uApiBpG4aH62Oimq1X3$ <https://urldefense.com/v3/__https://meetingorganizer.copernicus.org/EGU23/session/45056__;!!IKRxdwAv5BmarQ!fLXA3kivupxUpSinIFHAgTcjYtucGN1RidP9r6i-cU72aY4qdciXfF9vw_FjTpEikT2YA_8LgVF3xWfEyB2hxxWegA$> We look forward to seeing you in Vienna!
