Hi Whitham, there are several lightning detection systems in place for monitoring eruptions, I think the man to talk to would be Steve McNutt (steve@giseis.alaska.edu). He's gone till January 4th, but should be able to talk after that. Thanks! -Seth -------- Whitham D.

While the distance shown is anomalous, the direction of some activity is about right for Mt. Cleveland. I know there is significant lightning activity associated with ash plumbs and eruptions (I observed and recorded Mt. Redoubt in 2009, see here: http://www.reeve.com/mt_redoubt.htm) and would like to try correlating my data in time with reports of activity at Mt. Cleveland. Could you comment on this and also point me to where I can find reported times of activity? Thanks for your help. -- Seth Snedigar Alaska Volcano Observatory Alaska Division of Geological and Geophysical Surveys seth.snedigar@alaska.gov 907-451-5033 http://www.avo.alaska.edu/
