reservoirs can be damaged from an earthquake and cause flooding on the Los Angeles area. Depending on what area the earthquake is centralized, another concerned with flooding can be the threat of tsunamis. Tsunamis are caused by an earthquake out in the ocean and can create huge waves and destroy many buildings in its path when it hits land (MTU, 2007).

The final hazard to be aware of from and earthquake is fire. Many fires are started from broken gas lines and power lines and can be hard to contain if the main water lines underground have been broken (MTU, 2007). Origin and Causes of Earthquakes The surface where the two blocks can slip is called the fault or fault plane. The site below the earth’s surface where the earthquake begins is called the hypocenter , and the site immediately above it on the surface of the earth is called the epicenter . The main reason an earthquake occurs when two blocks of the earth suddenly slip past one another in a rough manner. The friction between these two blocks causes them to jam up and the motion along the fault comes to a temporary stop. As these two blocks continue to stay jammed up, the energy continues to build up and the rocks surrounding the jammed area begin to bend and buckle. Finally, the built up energy becomes strong enough along the fault and the two blocks slip and the energy in the rocks is released as the violent tremors of an earthquake. Relation between the Plates and Earthquakes The theory of plate tectonics is that the Earth’s surface is made up of many individual plates, which move, and shift continuously, which causes the Earths outer layer to change. The results of an earthquake come from the movement of the plate tectonics. The zones that run along the plate boundaries are the reasons for geological activity within the regions on Earth. Earthquakes are normal along all types of boundaries and occur all over the world. The Pacific Ocean is called

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
