Tomofumi Kozono studies volcanic phenomena with theoretical and numerical approaches based on fluid dynamics. In particular, he is working on the basic physical processes that control the dynamics of magma ascent in volcanic conduits. He also manages the Japanese website of IVHHN and is standing in for Dr Yasuhiro Ishimine who has moved to a postdoctoral position at RIKEN (The Institute of Physical and Chemical Research) in Saitama, Japan to conduct computer simulations of fluid flows and particle deposition in the human lung.

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.
