An earthquake is a sudden, rapid shaking of the ground caused by the breaking and shifting of rock beneath the Earth's surface. This shaking can cause buildings and bridges to collapse; disrupt gas, electric, and phone service; and sometimes trigger landslides, avalanches, flash floods, fires, and huge, destructive ocean waves (tsunamis). Buildings with foundations resting on unconsolidated landfill, old waterways, or other unstable soil are most at risk. Buildings or trailers and manufactured homes not tied to a reinforced foundation anchored to the ground are also at risk since they can be shaken off their mountings during an earthquake. Earthquakes can occur at any time of the year. www.osha.gov
Vibrations of the earth caused by the rapture and sudden movements of rocks that have been strained beyond their elastic limit. Health, Safety & Environmental Care Department Slide 6: How Energy is Stored in Rocks Rocks bend until the strength of the rock is exceeded
Rupture occurs and the rocks quickly rebound to an un-deformed shape
Energy is released in waves that radiate outward from the fault Slide 7: The Focus and Epicenter of an Earthquake An earthquake’s point of initial rupture is called its Focus or Hypocenter.
The term Epicenter refers to the point at ground level directly above the hypocenter. Health, Safety & Environmental Care Department Magnitude Properties : Magnitude Properties Slide 11: EFFECTS OF AN EARTHQUAKE: Fires
Tsunamis (Tidal Waves)
Spills of hazardous chemicals / Broken gas lines
Violent Ground Motion;

What to Do Before an Earthquake Strikes?
Make sure you have a fire extinguisher, first aid kit, a battery-powered radio, a flashlight, and extra batteries at home.
Learn first aid.
Make up a plan of where to meet your family after an earthquake.
Don't leave heavy objects on shelves (they'll fall during a quake).
Anchor heavy furniture, cupboards, and appliances to the walls or floor.
Help your family and neighbors / community get ready for any natural disaster

What to Do During an Earthquake? Health, Safety & Environmental Care Department Earthquake Safety Tips : Earthquake Safety Tips If you are indoors, you should:
Drop, cover, and hold on.
If you are not near a desk or table, drop to the floor against the interior wall and protect your head and neck with your arms. Avoid exterior walls, windows, hanging objects, mirrors, tall furniture, large appliances, and kitchen cabinets with heavy objects or glass.
DO NOT use elevators!
Do not go outside! Health, Safety & Environmental Care Department Earthquake Safety Tips : If you are in a motor vehicle:
stop the car and stay inside until the earthquake stops. Stop as quickly as safety permits and stay in the vehicle. Avoid stopping near or under buildings, trees, overpasses, and utility wires.
Proceed cautiously once the earthquake has stopped. Avoid roads, bridges, or ramps that might have been damaged by the earthquake. Earthquake Safety Tips Health, Safety & Environmental Care Department Earthquake Safety Tips : If you are outdoors, you should;
Move to a clear area if you can safely do so; avoid power lines, trees, signs, buildings, vehicles, and other hazards.
Don’t use matches, candles or any flame; broken gas lines and fire does not mix! Earthquake Safety Tips Health, Safety & Environmental Care Department Slide 19: Health, Safety & Environmental Care Department Earthquake Safety Tips:
What to Do After an Earthquake? Earthquake Safety Tips : Health, Safety & Environmental Care Department Expect AFTERSHOCKS
Check yourself and others for injuries. Provide first aid for anyone who needs it.
Check Utilities - water, gas, and electric lines for damage. If any are damaged, shut off the valves. Check for the smell of gas. If you smell it, open all the windows and doors, leave immediately.
Be careful around broken glass and debris. Wear boots or sturdy shoes to keep from cutting your feet.
Stay away from beaches. Tsunamis sometimes hit after the ground has stopped shaking. Earthquake Safety Tips Earthquake Safety : Health, Safety & Environmental Care Department Earthquake Safety http://www.uwiseismic.com/
