I run the YouTube channel GeologyHub, and I especially enjoy covering volcanoes in Alaska. I was previously assured that the USGS/AVO photos displayed on this website were public domain (which I credit as such) unless stated otherwise. For example, some photos are "courtesy of the photographer". I have not used these photos as I believe the photographer has NOT submitted them into the public domain. Please verify if this is correct. Also, I am unsure of if I can use photos taken by UAF-GI (unsure of copyright policy on that). For example, can I use the photo at https://avo.alaska.edu/images/image.php?id=182216 without express permission in my youtube videos, or is it copyrighted and thus I need to ask for permission from UAF-GI (since it says AVO/UAF-GI)? On the topic of Mount Edgecumbe, I wish to know the exact approximate depth the magmatic intrusion is occurring at. Also, are they any (even incredibly "rough") approximations of how much magma is moving at depth? How does this relate to the typical depth of its magma chamber? I am quite curious as Edgecumbe's magma chamber should theoretically hold at least 5 km^3 based on previous eruptions in the last 10,000 years. ---------------------------------------------------------------- REMOTE IP ADDRESS: 38.29.218.235 USER AGENT/BROWSER: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/100.0.4896.127 Safari/537.36 Edg/100.0.1185.50 REFERRING PAGE: https://avo.alaska.edu/contact.php
