Dear colleagues,



We would like to draw your attention and encourage your submission to the
session â??Monitoring and modeling active volcanic lakesâ?? at the IAVCEI 2023
Scientific Assembly in Rotorua, New Zealand (30 January- 3 February 2023).



*Session description*

A lake in the crater of a volcano can be a subaerial exposure of an
underlying hydrothermal system and/or a sink for rising volcanic gases. As
such, active volcanic lakes present a specific set of hazards,
including phreatic
or phreatomagmatic eruptions, lahars triggered by lake overflow, Nyos-type
limnic gas bursts and decrease in the mechanical stability of volcano
flanks resulting from prolonged â??acid attackâ?? by aqueous fluids that seep
into the subsurface.  Multidisciplinary approaches (e.g., geophysical and
geochemical measurements and numerical and probabilistic modeling) show
promise to reveal precursory signals of eruptive activity, better
understand eruption mechanisms and improve hazard forecasting and
mitigation.  We invite contributions from a broad range of disciplines
(geochemistry, geophysics, limnology, hydrogeology) that seek to measure,
monitor and model active volcanic lakes with the goals of understanding
activity in the underlying volcano and hazards mitigation.



The deadline for abstract submission is 2 September 2022.  Abstracts can be
submitted at: https://urldefense.com/v3/__https://confer.eventsair.com/iavcei2023/call-for-abstracts__;!!IKRxdwAv5BmarQ!bJvXDZ4CYPd9grqgqE_sqA4lBNcQPFFnme9bsDSThc27BtCWNyzllPJF_NFxLa4Hb9IMz7le6guQCigD$
