IVHHN has three categories of members:

  1. Expert Members. Members who specifically study volcanic emissions and related health hazards.
  2. Organization Members. Members who are directors or presidents of volcano observatories and organizations.
  3. Corresponding Members. Members who have a broad interest in IVHHN and would like to be kept informed of workshops and information.

If you consider that you would like to become an Expert Member of IVHHN, please send a short CV, a paragraph describing your research (less than 200 words if possible) and a list of relevant publications to This e-mail address is being protected from spambots. You need JavaScript enabled to view it . With your permission, details of your research interest, position and publications will be available on this website. Please state whether you are prepared for your contact details to be available online.

Organization members act as the conduit for the dissemination of information from IVHHN to volcano observatories, and hence to local emergency managers and medics involved in eruption management. If you are the director of a volcano observatory, please contact This e-mail address is being protected from spambots. You need JavaScript enabled to view it . We also request that volcano observatories collect fresh samples of volcanic ash following eruptions. These can be sent to Claire Horwell for characterization. One of the aims of IVHHN is to build up a comprehensive database of well-characterized volcanic ash samples.

Corresponding Members are welcome to join the IVHHN mailing list. This mailing list is open to anybody with an interest in IVHHN who would like to be kept informed of IVHHN activities. To join the mailing list, please send an email to This e-mail address is being protected from spambots. You need JavaScript enabled to view it and, in the text of your message (not the subject line), write: join IVHHN FIRSTNAME LASTNAME (replacing 'FIRSTNAME LASTNAME' with your first name and last name).

IVHHN has an article under the Guidelines tab which used to be called 'Recommended Face Masks'. This has now been updated to 'Information on face masks' and is an interim page whilst the Health Interventions in Volcanic Eruptions project investigates which types of respiratory protection are effective in protecting the general population from volcanic ash inhalation. Please note that the translations in Spanish, Japanese and Portuguese have not yet been updated.
