1-1-1-1-1-1-1-1-1-1-1-1-1-1 From: Corrado Cimarelli <cimarelli@xxxxxxxxxxxxxxxxxxx> Dear Colleagues, Please consider submitting your abstract to the session â??Volcanic Electrification and Lightning: Causes and Effectsâ?? at IAVCEI 2023 under the Symposium: Using field data, geophysics, geochemistry, statistics, and modeling to probe volcanic and plutonic systems. Outline: The study of the electrical signature of explosive eruptions is emerging as a tool for real-time detection of ash emissions and for safely probing the internal structure of the eruptive column/plume during their evolution in space and time. This session will focus on volcanic electrification, volcanic lightning and the various methods by which they are studied and utilized to further knowledge of explosive eruption phenomena, ash column/plume dynamics and atmospheric microphysical processes. This multidisciplinary session seeks contributions from studies including, but not limited to: 1) Laboratory examination of electrification phenomena due to tephra and/or hydrometeor interaction, ice nucleation, and electrical discharges; 2) numerical modeling to decipher the atmospheric impacts of volcanic lightning both now and in Earthâ??s history; 3) remote sensing methods that use electric potential and volcanic lightning as a tool for diagnosing eruption dynamics and transitions in eruptive activity; 4) analytical methods to identify volcanic lightning evidence in the stratigraphic record of current or previous eruptions; 5) effects of electrification on transport, deposition and remobilization of tephra. Other methods to deduce the causes and effects of volcanic lightning are also encouraged, particularly those that are informed by other relevant disciplines outside volcanology, such as meteorology, lightning physics, and electrical engineering. **Deadline for submission is 2 September 2022** Submit your abstract here https://urldefense.com/v3/__https://confer.eventsair.com/iavcei2023/call-for-abstracts__;!!IKRxdwAv5BmarQ!cNWgynSqdc2YHaFHxgE4o0ftQg8JPOjKMM6GnPKhCZfueLaWm74bmd6kVqKQMTfkcuaK5ZwQTyl4XY7a$ <https://urldefense.com/v3/__https://confer.eventsair.com/iavcei2023/call-for-abstracts__;!!IKRxdwAv5BmarQ!cKs5P3s2ibDNO5DonAoWwXLYgEib6w1sKaS26Wf17x81uKGw7R2n3_N8szFXGCOrAMTYc2-RnWQqFBpOZjgNTXpdwOIR$> See you numerous in Rotorua! 1-1-1-1-1-1-1-1-1-1-1-1-1-1 ------------------------------
