Dr Shane Cronin
Soil and Earth Sciences Group
Shane Cronin is an expert in the effects of fluorine and sulphur on human and animal health. He has investigated fluorine levels in the volcanic ash ejected in the 1995 eruption of Mt Ruapehu, and in the active Ambrym volcanic system in Vanuatu, where elevated F levels occur in the drinking water of local inhabitants.
Shane also works in volcanic hazard assessment and disaster management in New Zealand and the Pacific Islands (e.g. Fiji, Solomon Islands, Vanuatu, Tonga and Samoa). He currently leads a multidisciplinary 6-yr program on Volcanic risk analysis for New Zealand volcanoes, including activities ranging from the numerical modelling of volcanic mass flows to the petrological modelling of eruption dynamics and hazard potential. Great effort has also been put into making volcanic risk information relevant to industry, local-authority and community (especially Maori-communities) user groups in planning their risk-management efforts.
In addition, Shane is involved in ongoing studies of relevance to volcanic health. His recent research is focussed on:
In May –July 2009 he carried out a rapid response survey of volcanic heath impacts from increased activity at Ambrym volcano for the WHO. Results of this are currently being presented to the Vanuatu Authorities and he will be publishing it in due course.

Download our pamphlets on preparing for ashfall and on the health hazards of ash. They are designed for mass distribution at the onset of new eruptions. They are now avaiable in English, Japanese, French Spanish, Portuguese, Swahili, Indonesian and Icelandic with Italian versions being available shortly. Please see our Pamphlets page for further infomation.
FACE MASK USE
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.
