Plate tectonic press release
For legion(predicate) years people always called southern California Americas Promised Land because of Its pretty-pretty weather, b each(prenominal)es and Its film industry. Now with 13 million habitants its been looked at as risk of infection city. Not only does the San Andrea Fault, marking the conservative margin between the peace-loving and North American ordered seriess, cross Southern California, but LA was reinforced across a myriad of transform faults (Case Study For dual Hazards Los Angels, California, Usa. , 1999). These Include the Santa Monica fault, the San Fernando fault, and the Northerner/Santa Barbara fault. Although the most violent land flickers are predicted to occur along the San Andrea Fault, earth movements frequently occur along most of the lesser known faults. The most recent of 11 seisms to affect LA since 1970 occurred in January 1994, focusing in the Northerner area It registered 6. On the Richter scale, lasted for 30 seconds, and was followed by a fterwardsshocks lasting several days, The quake killed 60 people, injured several thousand, caused buildings and sections of freeway to collapse, Ignited fires following a gas leak and explosion In the Granddad Hills area, and left 500,000 homes without causality and 200,000 homes thou water supplies (Case study For Multiple Hazards Los Angels, California, Usa. , 1999). Thered many reasons as too what causes the temblors and how they started.The earthquakes in California are caused by movements of huge blocks of the earths gall known as the Pacific and North American plates. The Pacific crustal plate is moving in the North West direction and is scraping twisting North America at a rate of two Inches a year. About two-thirds of this movement occurs on the San Andrea Fault and some parallel faults- the San Action, Elisions, and violet faults (Southern California temblors And Faults, n. . ). Over time, these faults minor earthquakes.Lets talk about plate tectonics. There six majo r plates and they are named after the continents that they are insert in, such as North America, Africa, and Antarctic. The plates make out the outer type of the earth called the lithosphere. One way a mountain is formed is through and through convergent boundaries which is when plates serving land masses collide, the crust crumbles and buckles into mountain ranges ( weighing machine Tectonics, 1996-2014). Mountain ranges are also formed through diverging boundaries in the ocean. Magma from deep inside the earths antler trick ups towards the surface and pushes apart two plates and mountains and volcanoes rise along the seam (Plate Tectonics, 1996-2014). On January 17 1994 an earthquake rocks Los Angels, California, killing 54 people and causing billions of dollars in damages. The Northerner quake (named after the San Fernando Valley community near the epicenter) was one of the most damaging in U. S. History (Earthquake Rocks Los Angels, 2014). According scientists using a new mod el to qualify the probability of big quakes, California has more than a 99% discover of having a magnitude 6. r larger earthquake within the following 30 years (Earthquake Rocks Los Angels, 2014). How prepared are you for an earthquake? community with mobile homes and homes not attached to a foundation are at a more greater risk for damage. Buildings resting on unstable reason such as landfills are also at a much greater risk of damage. The Red Cross suggest that you Become aware(predicate) of fire evacuation and earthquake unspoiledty plans for all of the buildings you occupy regularly. foot safe places in each room of your home, workplace and/or school.A safe place could be under a piece of furniture or against an interior ring way from windows, bookcases or tall furniture that could hang up on you. Practice drop, cover and check out on in each safe place. If you do not have unbending furniture to hold on to, sit on the floor next to an interior wall and cover your he ad and neck with your arms. Keep a flash informal and sturdy shoes by each persons bed in case the earthquake strikes in the middle of the night. Make sure your home is securely anchored to its foundation. drive extraneous and brace water heaters and gas appliances to wall studs. Bolt bookcases, china cabinets and early(a) tall furniture to wall studs. Hang eave items, such as pictures and mirrors, away from beds, couches and anywhere people sleep or sit. Brace overhead light fixtures. Install strong latches or bolts on cabinets. Large or strong items should be closest to the floor. Learn how to shut off the gas valves in your home and keep a wrench handy for that purpose. ( Prepare For An Earthquake, 2014) Now that you know all there is to know about earthquakes and how to entertain yourself in them, you will better keep yourself protected from the dangers of them.
