Hi James - Volcanic ash is a serious hazard, and one that people in the US and other countries have studied - study is ongoing, and so my list is neither comprehensive or up-to-date, but I have put it at the end of this email. We would also be interested in seeing your thesis when complete, if you don't mind sharing. This email is in reply to inquiries you sent to the State of Alaska Division of Geological & Geophysical Surveys and to the Alaska Volcano Observatory. Thank you, Cheryl Cameron Non-comprehensive list of volcanic ash studies and educational materials global: USGS Volcano Hazards Program / Volcanic Ashfall Impacts Working Group ashfall hazards and mitigation website: https://volcanoes.usgs.gov/volcanic_ash/ <-- this site is very comprehensive.

My name is James Ferguson and I work as an Emergency Manager for the Air Force, at Fort Eustis, Virginia. I am doing my thesis for my master's degree in Emergency and Disaster Management on the subject of volcanic ash. I attend American Military University. My research will collect all of the hazards ash presents as well as ways in which it can be cleaned up. Also I will gather ash preparedness educational materials that officials have created for the public. The effects on first responders operating in ash environments is another aspect I will be looking at. This information is intended to make Emergency Managers and Public Works officials aware of different experience other countries have gone through after eruption. There may be those officials who have not experienced an eruption incident during their tenure. This would present a variety of ways to conduct emergency response, work and develop mass warning and notification as well as educational materials for use in ash environments. If you have any books, studies or other documents that you are aware of that you think would be helpful, I would appreciate it very much. Thank you.
