An earthquake is caused by a sudden slip on a fault. When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earths crust and cause the shaking that we feel. In California there are two plates - the Pacific Plate and the North American Plate.
How do earthquakes happen for kids?
Earthquakes usually occur on the edges of large sections of the Earths crust called tectonic plates. These plates slowly move over a long period of time. Pressure slowly starts to build up where the edges are stuck and, once the pressure gets strong enough, the plates will suddenly move causing an earthquake.
What is earthquake Short answer?
An earthquake is the sudden movement or trembling of the Earths tectonic plates, that creates the shakes of the ground. This shaking can destroy buildings and break the Earths surface. Seismology studies about the cause, repeats, type and size of earthquakes. Earthquakes are measured using watching from seismographs.
How do earthquakes occur tectonic plates?
Earthquakes occur along fault lines, cracks in Earths crust where tectonic plates meet. They occur where plates are subducting, spreading, slipping, or colliding. As the plates grind together, they get stuck and pressure builds up. Finally, the pressure between the plates is so great that they break loose.
Where is the safest place to go in a earthquake?
Stay Safe During an EarthquakeDROP down onto your hands and knees before the earthquake knocks you down. COVER your head and neck (and your entire body if possible) underneath a sturdy table or desk. HOLD ON to your shelter (or to your head and neck) until the shaking stops.
