IVHHN - The International Volcanic Health Hazard Network

VolcanoThe International Volcanic Health Hazard Network (IVHHN) is an umbrella organisation for all research and information 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, in particular the health hazard of inhaling volcanic ash and gas. IVHHN was launched in 2003 and is an IAVCEI Commission.

New Volcanic Ash Leachate Protocols published!


IVHHN is proud to announce publication of a new set of protocols for volcanic leachate analyses. This report was the outcome of a two-day workshop held at the Institute of Hazard, Risk and Resilience, Durham University, UK, in 2011, attended by the authors (experts in leachate methodologies). A 2005 review of ash-leachate studies (Witham et al., 2005), which made preliminary recommendations on standard methods for characterising ash leachates, was used as the starting point for discussions at this workshop.

The purpose of this protocol is to recommend clear, standard and reliable methods for the rapid assessment of hazards from leachable elements, each applicable to specific purposes.
