Earthquakes

           Oceanside, California consists of many active, geological events. The most predominate geologic event is earthquakes. California itself receives over 500 active earthquakes a year.

            California consists of two tectonic plates, known as the North American plate and the Pacific plate. The two plates together form the Andreas fault, a transformation fault, which is a very large strike, slip fault. This fault goes all the way up California but the last time the San Andres released energy was many years ago. Although, Southern California itself includes over 300 smaller faults that brings earthquakes that are more often occurring but also not as large seismic waves that the San Andres might bring. Every earthquake creates three kinds of waves. P, primary waves and S, Secondary travel downward into the earth, and L, the last waves that travel along the top of the crust.

            Because of the high volume of earthquakes, plate boundaries moving and pressure being released that causes the earth to shake, Southern California is more likely to receive damage to buildings, ruins to concrete grounds, fires, mass wasting and even tsunamis. This can be very detrimental and concerning to people that live in California. Tragedy can strike at anytime. In the last ten days California has received over 14 earthquakes, all of them with a smaller magnitude doing barely anything to the people, most probably not even large enough for people to really notice. What the people need to be concerned with are the larger magnitude earthquakes, which are thankfully not as occurring as the smaller earthquakes out of the San Diego area. People are educated on how to react during a small earthquake and many homes in Southern California come with insures for any earthquake damage. Homes and buildings today are even designed differently in hope that an earthquake would not do as much damaged.  Living in California people need to be educated on the risk and hope for the best. The aftermath of the earthquakes is what usually does most harm, the failing of buildings, fires formed and the mast wasting.
