Hello Ron- I've forwarded your question to the geologist who made the figure. As we're a lean staff and Bogoslof is still erupting, it might be a little bit before we have an answer. Thank you, Cheryl Cameron -------- Ron Schott wrote: The figure that quantifies land added and lost on Bogoslof Island as of 12/25/2016 (http://avo.alaska.edu/images/image.php?id=103641) fails to quantify land added E/SE of the new vent (as well as the land lost - presumably to erosion - on the SE tip of the island). The new land E/SE of the new vent would appear to be sufficient to nearly balance the overall losses and gains - a significantly different conclusion than that presented in the analysis as published in the figure. -- Cheryl Cameron Geologist, Alaska Volcano Observatory Alaska Division of Geological & Geophysical Surveys voice: 907-451-5012 fax: 907-451-5050
