IVHHN has developed some briefing notes to help emergency managers and government agencies make decisions on protecting communities from volcanic emissions. The following documents were written, with urgency, for the St Vincent 2021 eruption and continue to be edited.

  1. Briefing note on the health impacts of eruptions (last updated 16 April 2021)
  2. Briefing note on water quality management (last updated 28 June 2021)
  3. Briefing note on air quality management (last updated 16 April 2021)
  4. Briefing note on ash clean-up health & safety (last updated 20 April 2021)
  5. Briefing note on interpreting gas measurements (last updated 13 May 2021)


Additionally, we recommend the following slide set on ash clean-up, developed by Dr Josh Hayes (Earth Observatory Singapore) and Prof Tom Wilson (Universit of Canterbury, NZ). Clean-up afer volcanic eruptions - considerations for St Vincent slide set

This slide set compliments posters commissioned by USAID, the Volcano Disaster Assistance Programme and US Geological Survey, providing concise best practice information for critical infrastructure managers to effectively prepare for, respond to, and recover from ash-producing volcanic eruptions. https://www.gns.cri.nz/Home/Learning/Science-Topics/Volcanoes/Global-Ash-Impact-Posters
