Earthquakes can occur 1,000 times a day. Most happen in the Pacific Ocean because of all the volcanoes on the ocean floor. This area is called The Ring of Fire. Most Earthquakes are not detectable. However, sometimes intense stress can build up between the giant rocks slabs. When the stress is released, huge vibrations, called seismic waves are pushed through the rock and the earth's surface. This usually starts when were plates are weak,called fault zones. Seismic waves can be measured like this: []
 * 3-5 minor/light
 * 5-7 moderate to strong
 * 7-8 major
 * 8 or more is great

The largest earthquake was a 9.5 in Valdivia, Chile in1960 The most deadliest earthquake ever recorded was January 23, 1556 in Shaanxi, China killing over 800,000 people!

=**__Safety__** := = If you are inside you should stay there. Don’t run downstairs or outside where you could get hit by falling things. If you are outside, go into the open away from buildings, trees and power lines. If you are in a car, stop, but away from bridges and overpasses. Turn off the gas in the house. Don’t turn the gas on again. Do not use matches or lighters. Stay off the phone, use only for emergency. Remember that policeman and fireman may not be able to get to you. The most important thing to do to prepare for an earthquake is to MAKE A PLAN TODAY! =
