The influence of the earthquake disaster and earthquake disaster mitigation measures analysis
There are three main reasons for the earthquake hypothesis , namely \" elastic rebound \", \"the magma shock to say\" \' said phase change .\"These three hypotheses have some reasonable, but what causes earthquakes, pending further study
The Characteristics of earthquake disasteriudden and strong, destructive big , serious secondary disasters , far-reaching social , defense difficult.Sudden strong make it difficult to predict and the effect of prevention becomes weak .His devastating is to see, such as the Tangshan earthquake which caused 24.2 million deaths , injuries 16.4 million.The Secondary disasters such as fires , floods , tsunamis , landslides , mudslides , gas leaks, pandemics, radioactive contamination is also very scary .2004 Indian Ocean tsunami, which has razed to the ground in several cities .Due to sudden strong earthquake , suffered heavy casualties, huge economic loes , tend to produce a chain reaction , causing a huge impact on a region or even a social life and the country \'s economic activity , resulting in a profound impact on society.Compared with floods, droughts, typhoons and other weather disasters , earthquake prediction is much more difficult .At the same time , improve the seismic performance of buildings , requires a lot of capital investment , this is not a short period of time can do.
Although it is difficult to predict the devastating earthquake , but there is a history of China succefully predicted miracle.At 19:36 on February 4, 1975 occurred in Liaoning Haicheng earthquake prediction is accurate , which makes more than 100 million people in southern Liaoning Province promptly evacuated their homes and workplaces .This succe is due to the abnormal situation in a timely manner to collect a large number of earthquake precursors , and timely induction, analyze, summarize the results , thanks to good policies of prevention group prevention and measured .Haicheng earthquake prediction can be succeful, profeional workers contributed to the earthquake, but it was the implementation of \"ma monitoring and prevention\" approach, also played a crucial role.Generally speaking, profeional workers in the earthquake, earthquake forecasting long, medium, and have a good chance, but the short-term forecasting, grasp not so big.The earthquake disaster prevention, the short-term forecasting truly decisive.
