Growing Land Bulge in Oregon

I like stories like this. There's a growing bulge in the land in central Oregon, covering about a 100 square mile area. The bulge, which scientists surmise is caused be either magma or water filling an underground cavern, is rising by about an inch and a half a year. It's located about 3 miles from South Sister, one of the Three Sisters volcanoes located west of Bend. South Sister last erupted about 2000 years ago and isn't considered likely to erupt any time soon. Scientists don't think the bulge is an imminent threat either.

I drove through the Three Sisters area about 9 or 10 years ago and found it to be one of the neatest and most desolate places I've ever seen. There's miles and miles of hardened black lava and little else and just off the highway (sorry, I don't recall which highway; I'm guessing it's 20 or 242) is an observation castle made out of lava rock with windows cut into the walls through which you can see half a dozen or so volcanoes. Pretty cool.
