Thank you for your reply. Also, it would be helpful if the caption on the AVO website could be updated to include the “Dr” in “Dr Grapenthin”. My prior post on Twitter of this graphic without attribution was an error in judgement. It won’t happen again, hence why I deleted the original post. I am planning another eventual video on Edgecumbe. It’s a fun (minor) oddity compared to the other basaltic composition less prominent cinder cones along the Aleutian east coastline. Will use the aforementioned graphic with attribution and context. If I end up not making a dedicated video, will save it for a short story in my weekly news segment. Also, out of curiosity, are any studies planned to date the 2 young cinder cones complexes in the St. Michael field? I am referring to the cones far south of the town in the southern end of the overall volcanic field. Sent from my iPhone

Hello Tim,

Thank you for reaching out to us. We're happy to answer questions about our science and products. Images or figures in AVO's image database that are created by AVO/UAFGI employees are available for use with proper accreditation to the photographer/creator and AVO, as our "use restrictions" line says. In the instance of that specific figure, it represents scientific results, analysis, and interpretation, so reproduction without attribution would also represent a lack of scientific integrity. In addition, that particular figure's caption is important for image interpretation and is the valuable scientific work of Yitian Cheng and Dr. Grapenthin, and should be treated as such. Any modifications or further interpretations that you might make should be clearly labeled as your own and not the opinion of AVO or its researchers.

For images or figures in AVO's image database that are donated from someone outside of AVO, the photographer has often given AVO the rights to use that image without extending those rights to everyone else -- in those cases, the image carries a line that the photographer must be contacted for further permission to use the image. It is always a best practice to reach out to individuals for permission.

Regarding your questions about Mount Edgecumbe specifically, we are continuing to analyze data and will continue to share our findings via our formal information statements (you can sign up to receive these by email at https://urldefense.com/v3/__http://volcanoes.usgs.gov/vns/__;!!IKRxdwAv5Bmar... ), and less formally via our image database, twitter, facebook, and instagram accounts.

Thank you ----------------

Greetings! 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://urldefense.com/v3/__https://avo.alaska.edu/images/image.php?id=18221... 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.
