Evacuations are underway on Ocracoke Island ahead of Hurricane Irene. Lucy Wallace is spokeswoman for the Ocracoke Ferry Office.

State officials say residents in eastern North Carolina should prepare for the worst if Hurricane Irene brings high winds to the area. Visitors began leaving Ocracoke Island this morning and local officials have issued a mandatory evacuation for residents starting tomorrow. Governor Bev Perdue asked coastal residents this morning to prepare an evacuation plan.

Bev Perdue: "We want folks there to take this storm seriously and to get prepared. We do this regularly in North Carolina. We know how to do it. We are preparing for the worst. Get that plan together today... please."

The town of Ocracoke and Hyde County has issued a state of emergency ahead of Hurricane Irene. There's a mandatory evacuation in place for visitors and a voluntary one for residents. But residents will have a mandatory evacuation starting at 5 am tomorrow. Hyde County spokeswoman Jamie Tunnell says people considering staying should heed the warnings.

People across North Carolina felt the 5.9-magnitude earthquake centered in Virginia.

Earthquakes might be rarer on the east coast than they are in the west. But Laura Wagner, assistant professor of seismology at UNC Chapel Hill, explains why tremors here can be felt over such long distances.
