The Three Sisters Volcano in Oregon is showing signs of unrest, as magma was confirmed to be moving underneath its edifice. This has pushed up the ground overlying the intrusion of magma, which is located approximately 3 miles west of the South Sister. We now know the composition of this magmatic intrusion, and this video will explain why this is important as it relates to what a future eruption, were one to ever occur, might look like. So, is an eruption likely? What is the context of this event? This video will answer these two questions, and discuss what might happen next at this volcano.
