Knoxville geologists are in a frazzle because earthquakes have been increasing in frequency around a recently discovered volcano. The earthquakes, which occur most often on Saturday afternoons, range anywhere in magnitude from 0.01 to 0.63. The volcano is located along the river across from the University of Tennessee Agriculture campus, and at least for now, has an upscale condominium development on it. This afternoon, steam began spewing from the nearby water treatment plant, a sign of impending eruption, according to first-semester geology students. The volcano was named for Saint Knoxpatch, the patron saint of area geothermal activity.
