Earthquake Preparedness Press Release Essay

How poop my family be prep atomic number 18d for an quake? This question haunts countless residents in the Los Angeles argona every day. Hopefully we here at the Earthquake Prepargondness Center rear end shed some light on how you can protect your family. My name is Darin Fort and I am the Director of Earthquake Preparedness for Los Angeles. As with whatever danger, knowledge of the event is of upmost importance. Some questions that should be asked by anyone who wants to defend their home against earthquakes are What are the origins and causes of earthquakes and what is the relation of earthquakes to family tectonics and faults in Los Angeles? What are some historical disasters associated with earthquakes? What are the risk of infections associated with earthquakes? What is the potential for proximo earthquakes in the Los Angeles arena?Earthquakes are started at the Earths crust. Our planet is made up of diametrical cuticles which float on a layer of molten material or mag ma much equivalent spud chips would float on top of a bowl of water. Scientists believe on that point could be as many a(prenominal) as 12 plates that make up Earths crust. These plates impinge on freely like bumper cars twist away from each other, moving side to side or later each(prenominal)y, and even smashing into each other. The verification behind plate tectonics lies in mountain ranges and island chains like the Hawaiian Islands, both are products of plate tectonics. Earthquakes originate from plate boundaries called faults. The tension and movement between the conflicting faults is what causes the shock waves referred to as an earthquake. When the military press between two conflicting plates is too much for the rock material to support, they can shift or break dramatically. The exact under demesne point where this occurs is the focus. Many people are familiar with the above ground version of the focus called the epicenter. When the plates crack or shift, shock waves are sent out from the focus.These waves come in three forms Primary, Secondary, and Surface. The surface wave is the one which causes damage to our cities and homes. Unfortunately, Los Angeles is located over an earthquake hot bed. there are two different kinds of plate boundaries located under the Los Angeles area. The first is called a transform plate boundary. In a transform boundary, such as the San Andres Fault, plates move in a lateral motion. estimate taking two pieces of rough cut wood and sliding them against one another. When the mightiness applied exceeds the capability of the splinters holding them together, they slip and then catch again when it meets new, stronger material. This is called strike-slip affect which is produced by transform plate boundaries. The other type of boundary located in the Los Angeles area is called a convergent boundary. Convergent boundaries are located where two plates are colliding into each other.The grinding and crushing action of the two converging plates depute shock waves out just as the transform boundary does. Los Angeles has been battling the effects of plate tectonics for centuries. The Los Angeles area has suffered several major events in recent history. The Fort Tejon Earthquake took place in 1857 and tremors from this quake were felt up over 350,000 square kilometers (USGS, 2012). The Fort Tejon Earthquake was one of the largest in calcium history and originated at a strike-slip boundary. The Parkfield Earthquake of 1901 was an event we all hope never happens again. Over 700 people lost their lives that day cod to the tremors which originated from the San Andres Fault (USGS, 2012). In 1994 a major event struck which killed many, injured thousands, and destroyed billions of dollars worth of property. in that respect were also major events which took place in 1881, 1922, 1934, 1966, and most recently 2004 where property was damaged and even worse lives were lost.The hazards involved in an earthquake are countless. As stated earlier, the major damage causing force of an earthquake is the surface wave. The surface wave causes ground tremors that can knock building off their foundations and get under ones skin bridges crumbling down. If you are inside, either find the strongest area of the room or get under a table or desk and stay there. If you are caught outdoors get into the open, as far away from buildings, exponent lines, or any other type of tall or overhead structures. Another major hazard brought about by an earthquake is fire. Many times tremors from earthquakes can bring down power lines and demolish gas mains. In an event where you witness fallen power lines or leaking gas main, please move as far away from them as possible and contact rescue personnel as shortly as possible.Crumbling dams and levees can also lead to flooding in some areas. Stresses in certain structures like dams and levees tend to not present themselves until it is too late to escape the rising w ater. You should evacuate the area until safe and rescue personnel have had time to clear the area and inspect the affected structure. We can say, without hesitation, the earthquake activity in the Los Angeles is here to stay. Since we are located directly over plate boundaries, we will proceed to see seismic events. Plate tectonics, the driving force of earthquakes, is a natural process which has formed the dynamic world we live in today. Science Daily, a leading publisher of science news, recently print an article titled atomic number 20 Has More Than 99% Chance of a Big Earthquake indoors 30 Years, Report Shows (Science Daily, 2008).While the actual statistic is a 49% chance of a 7.5 or greater earthquake striking in the next 30 years, we are certain that seismic events will affect to plaque the city (Science Daily, 2008). Unfortunately, many of the lives lost in earthquake events could be prevented by taking precautional steps in our everyday lives. However, due to an inc reased population and congested city centers it is possible there could be more lives lost today if a major event were to strike. Please take all precautionary measures to keep you and your family safe during an earthquake.
