About Us

VolcanoThe International Volcanic Health Hazard Network (IVHHN) is an umbrella organisation for all research and infromation on volcanic health hazards. IVHHN currently involves 31 expert members from 25 international institutions as well as corresponding members who are signed up to the mailing list. Expert members of IVHHN work in diverse scientific disciplines such as volcanology, epidemiology, toxicology, public health and physical chemistry with a common aim of trying to determine the health effects of volcanic emissions. IVHHN was launched in 2003 and is an IAVCEI Commission.


IVHHN was launched with funding from the Leverhulme Trust (Research Interchange Grant) and was then funded by a Royal Commission for the Exhibition of 1851 Special Award.  IVHHN also receives administrative resources from the Institute of Hazard, Risk and Resilience, Durham University where it is hosted. IVHHN is directed by Dr Claire Horwell (Durham University).
