Mauna Loa 2022 Response

H-SAC and Proposal Guidelines

Currently the US volcano community is spread out over many academic institutions, includes several government agencies, is fragmented and would benefit from coordination. Often non-detection of initial volcanic unrest, and uncoordinated response to volcanic activity and eruptions leads to data of different types getting collected at different times and locations or not at all. This results in inefficient resource use and limited impact of the information obtained. 

The purpose of this Research Coordination Network is to enable, organize, and focus the collaboration of US academic researchers, the USGS, NASA, NCAR, NOAA, the Smithsonian (GVP) and foreign entities involved in volcano science. The goal of the enhanced collaboration is to advance our ability to adequately monitor the unrest and run-up to volcanic eruptions and once an eruption occurs, to adequately collect critical data and samples to develop next-generation physical/chemical models of volcanoes and through these understand processes of magma generation, transfer and eruption. 

This RCN is funded by NSF and resulted from recent community reports: ERUPT and SZ4D

We also collaborate with the SZ4D and MCS RCNs

September 30, 2021: CONVERSE is coordinating scientific activities between the Hawaiian Volcano Observatory and the non-observatory scientific community. The Kīlauea eruption just started again after a several months-long hiatus. We have formed a Hawaii Volcanoes Scientific Advisory Committee (H-SAC) that consists of a group of individuals from academia and the USGS. The H-SAC will evaluate proposals from the academic community for work on Kīlauea. Details on how to submit proposals are available here:

If you like to be involved in the science response to the Kīlauea eruption, please contact the disciplinary leader most closely related to your discipline and also submit a one-page proposal following the guidelines in the document above to H-SAC co-chairs Kari Cooper and Kathy Cashman.

Volcanic eruptions are often preceded by geophysical or geochemical signals. Below are some examples of some detected eruption precursors.

Deformation precursors at Okmok Caldera (from ERUPT report modified from Lu and Dzurisin, 2014)
CO2/SO2 as measured in the volcanic plume shows increase prior to Turrialba eruption (from SZ4D report and modified from de Moor et al., 2016)
CO2/SO2 ratios frequently show increases prior to eruptions. Above is a compilation of detected pre-eruptive changes (from Werner et al., 2019 https://www.cambridge.org/core/books/deep-carbon/carbon-dioxide-emissions-from-subaerial-volcanic-regions/F8B4EFAE0DAF5306A8D397C23BF3F0D7/core-reader)
