Facts about Earthquakes

Earthquakes are destructive to homes and closely built commercial buildings. They are catastrophic and in most cases cost lives. Governments pay a lot for insurance, evacuation and infrastructure repair. Research development in earthquake engineering aims to provide a sustainable solution to this. The institutions are assessing different regions that are potential for high magnitude earthquakes. It is costly to construct structures that can resist earthquakes. By inventing and reconstructing stable architectural designs people can handle variations of seismic effects of the earthquakes. An earthquake is simply a shock wave. The wave radiates through the Earth’s surface causing varying effects. The effects can be mild, prolonged or even unnoticed. Causes EarthquakeFacts One of the many facts about Earthquakes is that they are caused by movements within the Earth’s crust. The Earth is composed of the inner and outer core, a mantle and a thin crust that covers the mantle. The crust is most essential as a surface holding our oceans and massive continents. The crust is composed of various rocks called tectonic plates. They are connected like jigsaw puzzles constantly moving around. The plates slide moving horizontally some sliding beneath and others push and force the ground upwards. The plates can also move around or pull apart from each other. The Tectonic Plates These tectonic plates movement create massive pressure that causes friction. The plates are rocky and cannot smoothly by-pass each other. When pressure overcomes tectonic friction, there is a sudden movement of the plates. The rock waves are then radiated through the surface rock that is a foundation to buildings. Aftershocks can continue for different periods depending on the quakes magnitude.?????? Fault Lines Fault lines are particular areas where tectonic plates join. These faults are highly sensitive to earthquakes with a high and regular occurrence. The areas are closely and well- studied globally. The San Andreas is a fault running all the way across the West Coast in the North America region. Another Fault line is the one running between Papua New Guinea towards the Australian Continent. New Zealand, Taiwan, Tonga and Japan are also situated in this region. It is important for people living in these regions to protect themselves by constructing earthquake-resistant and protected houses. Responsible authorities can practice emergency earthquake drills to sensitive people regarding safety. Effects of Earthquakes Earthquakes have massive effects on our buildings and land. They cause tsunamis that have fatal effects to our life. The violent shakes resulting from earthquakes cause buildings to collapse leading to tragic deaths and heavy casualty cases. Earthquakes destroy extensive power lines and disrupt the natural gas supply pipes. Land terrain changes to accommodate the drift of the titanic plates. The land either collapses or drifts apart which in turn causes more disastrous effects. The friction causes water shocks that collide with land leading to creation of a bigger single wave that ends up sweeping the inland. The high water levels cause destruction and deaths. It is important to know how to protect yourself during an earthquake. Drop down onto your knees before the earthquake and cover your entire body or head. Hold firmly onto the closest shelter and be aware of what is going on around you. Be prepared to consciously move to safer areas to avoid injury. Earthquakes are natural and therefore require proper planning and anticipation procedure in case it happens. Finally, find more about earthquakes to be safe always
