Earthqukes
Earthquakes are caused by a sudden release of energy in the Earth's Crust. Earthquake's are the Earth’s natural means of releasing stress. They are caused when stress builds up with in the rocks in the earth’s crust and then is released in a sudden jolt.
The focus of a earthquake is the point beneath earth’s surface where rock breaks under stress and the points shift. An epicenter is the point on earth’s surface directly above the hypocenter of an earthquake. A hypocenter is the point where an earthquake actually occurs and it’s commonly under ground.
There are 3 faults in an earthquake, the normal fault, the reverse fault, and the strike skip fault. A normal fault is when a block of the crust has moved downward so the ground is uneven. A reverse fault is the same as an normal fault only instead of the ground moving down it moves up. A strike skip fault is when 2 blocks of the earth’s crust slide past each other forming a transform boundary.
There are 3 types of waves in earthquakes: the surface wave, the seismic wave, and the primary wave. The primary wave, or the P wave, is the fastest wave out of all of them, it goes through almost every thing.
There is a machine that can tell if an Earthquake is happening and how big it is, it's called The Richter Scale. It works like this; if you were to hold a pen in your hand perfectly still to a piece of rotating paper the line would be perfectly straight. If your hand started shifting, the way the plates in the earth can, the line wouldn't be straight any more. So when the lines on The Richter Scale aren't straight, it means and earthquake is happening because the movement of the Earth is causing the straight line to go jagged. The jagged lines can be measured to show the strength of the Earthquake, or the seismic energy released by an earthquake and was invented in 1935 by Charles Richter. Most earthquakes are located in the ring of fire because it's on a tectonic plate.
