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.

Part 4 of 4: What’s New with New Madrid? Surprisingly, the New Madrid seismic zone is considered as high of a seismic risk than the San Andreas Fault zone in California. This section highlights the apparent inconsistency with present estimates of seismic risk in the U.S. and Japan. Estimates of earthquake recurrence intervals can also be obtained from paleoseismology: evidence of prehistoric earthquakes preserved in the rock and sediment record.

Part 1 of 4: Review of Global Seismicity Predicting earthquakes has been a goal of seismology for centuries. In spite of increasing understanding of how faults work and earthquakes are produced, predicting when a damaging earthquake will occur is still very challenging. The fundamental information for predicting earthquakes is the earthquake record of when and where earthquakes occur. This section summarizes the distribution of seismicity on earth.
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.
