Research Expertise

Grant Heiken worked for NASA during the Apollo Program, in the Lunar Receiving Laboratory, as a geology instructor for astronauts, and conducted independent research on lunar surface processes, including volcanism. Since 1971 he has worked on the characterization and hazards of tephra and published the seminal book "Volcanic Ash" with Kenneth Wohletz in 1985 (see references below). In 1975 he moved to the Los Alamos Scientific Laboratory (now the Los Alamos National Laboratory) in New Mexico, where he worked in geothermal exploration and development, volcanic hazard analysis, the uses of volcanic rocks, basic research in explosive volcanism, and integrated urban science. Heiken has done research or exploration on volcanoes or volcanic fields in the United States (Oregon, California, New Mexico, Colorado, and Hawaii), Mexico, Guatemala, Honduras, Guadeloupe, St. Lucia, Italy, Greece, Ethiopia, and the Earth's Moon. He retired from LANL in 2003.

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.
