What should I NOT do during an earthquake?
- DO NOT turn on the gas again if you turned it off; let the gas company do it
- DO NOT use matches, lighters, camp stoves or barbecues, electrical equipment, appliances UNTIL you are sure there are no gas leaks. They may create a spark that could ignite leaking gas and cause an explosion and fire
- DO NOT use your telephone, EXCEPT for a medical or fire emergency. You could tie up the lines needed for emergency response. If the phone doesn't work send someone for help
- DO NOT expect firefighters, police or paramedics to help you. They may not be available.

Why should people in the eastern United States be concerned about earthquakes?
1) Severe earthquakes have occurred in the eastern U.S.: In November of 1755, an earthquake with an estimated magnitude of 6.0 and a maximum intensity of VIII occurred about 50 miles northeast of Boston, Massachusetts. Boston was heavily damaged. Other strong earthquakes recorded in the continental US were centered in southeastern Missouri near the border with Arkansas, Kentucky and Tennessee. In...
What are the Great ShakeOut earthquake drills?
The Great ShakeOut earthquake drills are based on scenario earthquakes that could effect the area if they were to actually take place. Great ShakeOut Earthquake Drills are an annual opportunity for people in homes, schools, and organizations to practice what to do during earthquakes, and to improve preparedness. These events are made possible through a collaboration between several agencies...
