Volcanoes not only erupt and spew objects into the air; they also move the ground.  Quite a bit, in some cases. 

So there's often some shaking with the baking.  Those are approximately the words of seismologist Stephen McNutt. 

He delivers the first of this year's geology lectures at Southwestern Oregon Community College in Coos Bay, explaining how seismologists study volcanoes.

We talk a fair amount about "The Big One," the anticipated Cascadia Subduction Zone earthquake that could hit 9.0 or higher in magnitude.  But it's not the only movement of the Earth we need to be aware of: we have volcanoes nearby as well. 

Mount St. Helens blew its top more than 35 years ago, but other peaks in the Cascades could come to life as well. 

That is the focus of Seth Moran, who directs the Cascades Volcano Observatory in Vancouver, WA.
