The Newberry Volcano in the state of Oregon is showing signs of unrest, as more than a dozen earthquake struck underneath its western caldera lake above its magma chamber. These earthquakes are highly unusual, representing the highest occurrence of earthquakes since sensors was emplaced on the volcano in 2011. Newberry's magma chamber is located at a mere 2 miles depth and contains a little under a cubic mile of molten rock. This material has produced several large eruptions, the last of which emplaced hundreds of millions of tons of obsidian in 690 AD. So, is an eruption likely? What is the context of these earthquakes? This video will answer these two questions and discuss what might happen next at this volcano.
