Research Expertise

Carol Stewart is an environmental chemist and comes from a background in environmental risk assessment. She is currently interested in volcanic ash impacts on aquatic environments and drinking-water supplies, and more generally in ash impacts on critical infrastructure. She works with the VATLAB group at the University of Canterbury, utilising a dual approach of carrying field investigations of impacts in areas impacted by volcanic eruptions, in conjunction with empirical testing of infrastructure components. Recent fieldwork includes investigations of the August 1991 eruption of Volcán Hudson, Chile; the May 2009 eruption of Chaitén, Chile; the recent activity of Tungurahua, Ecuador, and the May 2010 eruption of Pacaya, Guatemala.

PAMPHLETS

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.
