What is an earthquake?
An earthquake is the shaking of the Earth as a result of crustal movement. Crustal movement results from the deformation of the Earth's crust. Earthquakes are the Earth's natural means of releasing stress. More than a million earthquakes rattle the world each year. The West Coast is most at risk of having an earthquake. Earthquakes can happen at any moment, without warning. They can occur at any time of the year, day or night.
What causes an earthquake?
The surface of the lithosphere is fractured into tectonic plates.. Tectonic plates are in constant motion. When these plates move and collide, it causes movement and the Earth's surface shakes with great force. When the force is large enough, the crust is forced to break. When the break occurs, the stress is released as energy which moves through the Earth in the form of waves, which we feel and call an earthquake.
California is earthquake country, with more than 2,000 known faults crisscrossing the state. Scientists don't know when California's next great earthquake will strike, but they do know almost everything else about it, and the potential ramifications are terrifying: impotent rescue services, widespread fires, and no fresh water for months.
* 99.7% chance a 6.7M quake or larger will strike California. * 46% chance a 7.5M or greater earthquake will strike, likely in Southern California. * 68% chance a 7.0M quake will happen in Northern California.
Within the next 30 years, there is a:
California Earthquake Risks
What to do in an earthquake?
Drop down on your hands and knees. This protects you from falling over but allows you to move if necessary.
Cover you head and neck. If available, seek shelter underneath a sturdy desk or table to prevent objects from falling on you.
Hold onto your head and neck, and shelter if applicable, until the the shaking stops. Be prepared if the shaking shifts.
Stay inside until the shaking stop and it is safe to go outside. Research has shown that most injuries occur when people inside buildings attempt to move to a different location inside the building or try to leave.
How to be prepared
Be aware of fire evacuation and earthquake pans for the buildings you occupy regulary. Create an emergency plan for you and your family to follow in case of an earthquake. Know how and where your family will reunite if separated during an earthquake and conduct in home practice drills. Keep and maintain an emergency supplies kit in an easy access location. Be prepared to fend for yourself for at least three days, preferably for a week. Have food and water, at least a gallon of water a day per person. A fire extinguisher suitable for all types of fires, flashlights, a portable radio, extra batteries, blankets, clothes, shoes and money.
