Research Expertise

 

Tamar Elias is involved in the development and testing of volcanic gas and aerosol measurement techniques, using Kilauea Volcano and its ongoing eruptions as a natural laboratory. Current projects include ground-based and airborne studies of SO2 and CO2 emission rates, development of a real-time volcanic gas monitoring network, and volcanic gas composition studies. A variety of methods are used in this work including mini-ultraviolet spectrometers (FLYSPEC), FTIR spectroscopy, and infrared and electro-chemical-based analyzers and sensors. She also works with the USGS Volcano Disaster Assistance Program (VDAP) and University of Hawai`i at Hilo Center for the Study of Active Volcanoes (CSAV) to train foreign observatory staff in gas monitoring techniques.
 
Another main research focus involves examining the effects of volcanic emissions on ambient air quality and human health, and has resulted in collaborations with other volcanologists, health professionals, and land and disaster management officials. Ongoing projects include participation as a co-investigator for a respiratory health study, and developing strategies for educating and alerting populations living adjacent to volcanic emission sources.

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.
