New SSiRC initiative Volcano Response Plan after the next major eruption

The SSiRC activity has started a new initiative called Volres "Volcano Response Plan after the next major eruption" to prepare a plan for the next major volcanic eruption. This plan aims to raise the science questions behind the chemical and climate impacts of large volcanic eruptions to define measurement and modeling strategies which will augment our knowledge and can be used to forecast and mitigate their impacts on earth. For further information please contact Jean Paul Vernier ( or Claudia Timmreck (
