With the IAVCEI General Assembly fast, and finally, approaching, we wanted to make sure you knew about the session, described below, that focuses on *volcano geodesy*. The conference will be held January 30-February 3, 2023, in Rotorua, New Zealand. Details can be found at https://urldefense.com/v3/__https://confer.eventsair.com/iavcei2023/__;!!IKRxdwAv5BmarQ!ZZUt8MUIR5cvFevcPZlOhLAkaKQ2PV8CbX0jrZ_HY2iAgkqtC4rC0mnwKovzCKOwFdHTp0RgSZ7q_TLN$ <https://urldefense.com/v3/__https://confer.eventsair.com/iavcei2023/__;!!IKRxdwAv5BmarQ!apC2HibYdhSRtxmWbP-GM0ASIF7yk119DudCaCJehzIZWIrK-2PMRdiBjFZ_ODXnTEhB7ODrCe_HkyK8$> .

Surface deformation and gravity change provide insights into the location of subsurface magma reservoirs, their volumes, and their changes over time, which relate directly to the potential for future eruptive activity. Geodesy thus has a strong role to play in the interpretation of volcanic unrest, as well as investigating the magmatic and tectonic structure of quiescent volcanoes and the characteristics of hydrothermal systems. In addition, geodetic data are increasingly used in a number of non-traditional ways, for example, detecting ash plumes and mapping lava flows. We encourage contributions that make use of geodetic datasets to better understand volcanic processes and associated hazards, including: - Observations and interpretations of geodetic change at restless and erupting volcanoes and active hydrothermal systems - Insights into quiescent volcanoes based on geodetic investigations - New geodetic techniques and instrumentation - Methods for exploiting the ever-increasing volume of volcano geodetic data - Non-traditional uses of volcano geodetic data - Application of geodetic data to volcanic hazards assessment, also taking into account the temporal scales of the different geodetic techniques - Multidisciplinary studies that merge geodetic and other datasets - Studies of variable scales of volcano geodetic change, from individual eruptive vents to entire volcanic arcs 8-8-8-8-8-8-8-8-8-8-8-8-8 ------------------------------
