Sean Bemis put his hands together side by side to demonstrate two plates of the earth’s crust with a smooth boundary running between them. But that boundary is not always smooth and those plates do not always sit together neatly, which makes the earth’s crust a dynamic and complex surface.

A new earthquake-monitoring station has been added to the seismic network that is jointly operated by the Kentucky Geological Survey (KGS) at the University of Kentucky and the Department of Earth and Environmental Sciences in the UK College of Arts and Sciences. The station is located behind the Perry County Public Library in Hazard, Ky., in the southeastern part of the state.
