Mystery Bulge in Oregon Still Growing

Mystery Bulge in Oregon Still Growing:

Apparantly there may be a new volcano forming in Oregon.

BEND, Ore. (AP) -- A recent survey of a bulge that covers about 100 square miles near the South Sister indicates the area is still growing, suggesting it could be another volcano in the making or a major shift of molten rock under the center of the Cascade Range.

...The results of the late August survey won't be ready for weeks, but scientists have reached some conclusions about the bulge from past monitoring.

They say it probably began growing in 1997 and has been rising ever since at a rate of about 1.4 inches a year. It was first observed from space using a relatively new imaging technology known as radar interferometry that can measure changes in the Earth's surface.
