Understanding and Preparing for an EarthquakeAn earthquake is a sudden movement of the Earth's lithosphere (its crust and upper mantle) through the release of energy accumulated “in the form of low frequency sound”. waves (seismic waves)” along geological faults or by volcanic activity. There are three types of seismic waves: “primary waves (P) have a push-pull vibration type, secondary waves (S) have a slide-to-slide vibration type, and a combination of primary vibrations (P) and secondary (S) vibrations (HarperCollins Publishers, 2003). It can be measured according to the Richter scale. An earthquake is a natural geological phenomenon and there are more than 30,000 earthquakes strong enough to be felt around the world. This is due to the rapid release of elastic energy stored in rock under high stress. Once the rock is strained beyond its breaking point, it ruptures, releasing potential energy (Pe) in the form of a seismic wave. This can be explained by an elastic rebound mechanism, the “tectonic theory”. According to tectonic theory, the lithosphere (the outermost layer of the Earth) is made up of 7 different large plates: “the African, North American, South American, Eurasian, Australian, Antarctic and Pacific plates” (Plate Tectonic, http://www.cotf.edu/ete/modules/msese/earthsysflr/plates1.html). An earthquake is a natural process of plate movement and one of the most destructive energies on Earth. The distribution pattern of earthquakes across the continental United States can be divided according to different time zones. The continental United States has four different time zones: the Pacific Time Zone, the Mountain Time Zone, the Central Time Zone, and the Eastern Time Zone. First of all, most of the distributed earthquakes are in the Pacific Ti...... middle of paper ...... earthquake. Seismic events lead to the development of seismological tools to avoid being victims of natural destructive power and to understand how to prepare for the next earthquake. The difference between geological energy and biological energy is: Geological energy is the potential energy that is stored in the earth. crust (plate) and biological energy is energy stored in the form of known chemical ATP, which is chemical energy. Geological energy and biological energy are identical in terms of how they transform energy. Geological energy is released when two tectonic plates move in waves. But biological energy is released during metabolism: breaking chemical bonds in glucose molecules and releasing energy. In both cases, energy is stored in chemical form in biological energy and geological energy is stored in the earth's crust or rock..
