Hello Joan - Thank you very much for passing this account along to AVO. I have a lot of secondary sources that state there was an eruption at Makushin in 1907, but this is the first eyewitness one! It is really great to be able to add it to our information. Please also thank 'leelaht' for us. I've edited our entry for the 1907 event here: https://www.avo.alaska.edu/volcanoes/activity.php?volcname=Makushin&eruptionid=141&page=basic If I have written something in error, please let me know. Thank you again, Cheryl Cameron -------- Joan ARTHUR wrote: Sept 1, 1907, USS Thetis in Unalaska 'Between 5-00 and 5-30, heard two distinct explosions supposed to be from Makushin volcano. At 5-50, a thick shower of cinders and ashes from Mt Makushin swept over the harbor and continued until 6-30, when light rain set in. Vessel covered with thin coat of cinders and ashes. Washed down decks and paint work. At 8-00, light shower of ashes from volcano again swept over harbor continued generally until midnight.' The logbook page is viewable here: https://oldweather.s3.amazonaws.com/ow3/final/USS%20Thetis/vol612/vol612_069... and the report is in the 4pm to Mid(night) section. I'm not sure if the comment 'supposed to be from Makushin volcano' is sufficient although it is followed by 'At 5-50, a thick shower of cinders and ashes from Mt Makushin swept over the harbor' They are in Dutch Harbor, Alaska. The previous log page shows the weather for that day with East-South-Easterlies all day: https://oldweather.s3.amazonaws.com/ow3/final/USS%20Thetis/vol612/vol612_069... The recorder of the volcanic action from the logbook was our volunteer 'leelaht'. Please do contact me should you require any further information from OldWeather. -- Cheryl Cameron Geologist, Alaska Volcano Observatory Alaska Division of Geological & Geophysical Surveys voice: 907-451-5012 fax: 907-451-5050
