Hi Tina, Thanks for your observations about Sanford. We often get reports every year around March of venting at Sanford. After investigating these reports, we've found that this phenomenon is not related to volcanic activity but instead is most likely the result of the rising and cooling of most air. The steep rock face on Sanford contributes to solar radiation and development of these clouds. Rock falls in the area can also be a source of some of the rising clouds. Here are some links to photographs from previous years: March 2009: http://www.avo.alaska.edu/images/image.php?id=46791 March 2010: http://www.avo.alaska.edu/images/image.php?id=19559 We would be happy to receive your photographs and add them to our database. You can send them directly to me at janet.schaefer@alaska.gov. Please include the photographer's name, the date and time of the photograph, where the photograph was taken from (or look direction), and let us know whether or not we have permission to share the image on our public website and social media sites. If you'd rather us not share them, we will keep them for internal use only. As far as the earthquakes are concerned, there is no anomalous earthquake activity to be concerned about in the Tok and Tanacross area. Recent sonic booms have been felt in the region due to the military exercises taking place. These can rattle homes and windows and feel just like an earthquake. Here's a link to the Alaska Earthquake center recent earthquakes map. http://earthquake.alaska.edu/earthquakes Thanks again for contacting us with your observations. -Janet -------- tina parker wrote: on 29 mar 2018 saw mt sanford was venting from two vents and had snow all the way to the top. 13 may 2018 saw sanford with no snow on the top after it had just snowed up there on 13 may 2018. have pictures from both days. friends of mine how live in tok and tanacross are telling us about the earthquakes they are feeling up there all the time.
