“I think this has been known for a very long time.”
I don’t think the large pulsation has been known.
The writeup says this is the first time magma intrusions have been tracked from beginning to end. Presumably this is due to new tech.
But I didn’t open up the source because if this particular magma intrusion was really dangerous, I would think that fact would be in the headline or first paragraph.
So correct me if I’m wrong but this writeup is about new tech allowing tracking intrusions more completely.
