Here's an article, which is one of many on the topic very recently. This one explains the ground uplifting and the slowing of that uplift, and describes the magma chamber that lies under the park. This article tends to downplay the threat of an eruption of this volcano anytime soon. It's always good to look at both sides of a scientific discussion, and science is on both sides of the fence on this one - but most within the science community think that the volcano is very unlikely to erupt in our time. It's a very interesting discussion. Over time I will share papers on the topic.
