Earthquakes have?plagued?our lives for as long as people have inhabited the Earth. These dangerous acts of the Earth have result in?great damage to human beings. Earthquakes damage?depends on?what area is hit. If an unpopulated region is?struck, there will be low loss of life or property. If it hit a large city which is?densely?populated, there may be serious injuries and destruction. Earthquakes have the power to uproot trees and send them?crashing?into buildings. They can trigger landslides and cause flooding and tsunamis. Buildings and structures are also?at risk. It is interesting to note that tall buildings will suffer?the least?damage if they are located directly at the epicenter. This is because they can?withstand?the up-and-down motion of P-waves. S-waves, on the other hand, occur far away from the epicenter, and cause the greatest stress?by?shaking buildings from side to side. These buildings are often knocked off their foundations. Buildings with thick, heavy walls do not?resist?shock waves very well. Violent earthquakes often cause structures to collapse, burying people underneath. Brick buildings are the most?vulnerable. The shaking of the earth is sometimes not the greatest disaster. It is in the?subsequent?fires and folds that often the greatest damage?occurs. Predicting an earthquake until now has almost been technologically?impossible. With improvements in technology, lives have been saved and many more?will.?All that?remains?is to research?to what takes place before ,during,and after earthquake,This has been done for years to?the point that a successful earthquake prediction is theoretically possible. However,?accurate?prediction of earthquake may take more years. ? 地震困扰我们的生活,只要有人居住的地球。这些危险行为的地球造成了巨大的损害的人。
地震破坏取决于区域中。如果无人居住的地区,会有低的生命或财产损失。如果打到一个大的城市,人口稠密,这里可能是严重的损伤和破坏。
地震的力量将树木连根拔起,把他们撞上建筑物。他们可能引发泥石流,导致洪水和海啸。建筑和结构也有风险。有趣的是,高大建筑物遭受至少损害如果他们直接在位于震中。这是因为他们可以承受的上下运动p-waves.s-waves,在另一方面,发生远离震中,和造成最大应力撼动的一面。这些建筑往往把他们的基础。
建筑与厚,厚重的墙不resistshock波很好。大地震常引起建筑物倒塌,掩埋底下的人。砖建
筑是最脆弱的。地球晃动有时不是最大的灾难。它是在随后的火灾和水灾,通常最大的损害发生。 地震预测到现在几乎已在技术上是不可能的。随着技术的改进,生命得到拯救和许多更多。这一切仍然是研究发生了什么之前,期间和之后,地震。这已经做了多年的点,一个成功的地震预报理论上是可能的。然而,准确预测地震可能需要更多年。
