The focal point or hypocenter is the place where an earthquake starts.
Earthquakes are often caused by a sudden slippage in rock material along faults. This is usually at a tectonic boundary. These earthquakes are caused by friction and weakness in the crust. When this stress exceeds the friction and strength of the rock, the fault ruptures, causing a sudden slippage that releases stress energy in waves through the earth's crust.
The size of an earthquake is measured by how much it shook the ground. The distance from a fault affects how much shaking there is. Because faults are often many kilometers beneath the earth's surface it can be difficult to measure. Scientists, however, can use seismograms to help determine.
Seismograms help locate earthquakes because they show movement of the S and P waves that shake ground. Because P waves travel faster than S waves, they're easier to see on a seismogram and help us tell where an earthquake occurred.

Our earth's mantle layer is constantly being moved by the tectonic plates, which are constantly shifting. This nonstop motion creates cracks and stresses in our lithosphere. When faults get large enough, edges of plates become loose and earthquakes occur.
There are many different types of faults, but the most common cause of earthquakes is a slip along a fault line. CascadiaSubduction Zone is where some of the North American ocean crust is being pulled beneath. Because of its distance from a recognized plate boundary, earthquakes can occur in this region.
A large earthquake can cause serious damage to your home and other structures. The shaking can shake foundations and create landslides. It can also change the earth's surface to a liquid, which can cause destruction of buildings and trigger tsunamis.
Although you may not be able live through a major earthquake or tsunami, you can prepare your home to avoid structural damage. The most important thing to remember is to drop, cover and hold on!
Whether you're in your own home or on vacation, the most important thing is to know your risks for earthquakes. Make sure to research the most dangerous areas in your area and be prepared.
An earthquake could be your next neighbor
Major earthquakes can cause destruction in your neighborhood. It can destroy roofs, cause landslides and transform your neighborhood into a lake.
A crackling sound in the ground or a loud shaking in the air could be the first sign of an earthquake. If you are unsure of what to do next, please call your nearest emergency center.
