Natural disaster is one of the biggest problems facing the world today. Its harm is unimaginable. It has a huge impact on the healthy development of economy and society, and even threatens the survival of human beings.
In recent years, people have to pay attention to it. For example, people have suffered many disasters. Natural disasters such as Ya'an earthquake, British flood and Chile Sea earthquake have caused serious tragedies However, it has led to a large number of casualties.
The cause of natural disasters is human behavior, just like when human beings cut down trees, if we work hard, it will cause debris flow. We can reduce these natural disasters, and more people will be saved in less natural disasters. The international day for natural disaster reduction aims to advise all people to stop doing things that can lead to natural disasters.
Earthquake will cause great damage, many measures can be taken to reduce the damage of earthquake. This paper mainly studies earthquake prediction, prevention and preparation. People can predict earthquakes by observing the abnormal behavior of animals or detecting the changes of the earth or measuring the content of radon in water.
Architects design new structures to withstand earthquakes. People can regularly inspect and strengthen their homes, have necessities for survival at home, carry fire extinguishers and other appropriate tools, and even make earthquake emergency plans. If prediction is possible, people still have to do their best to prevent disasters by improving building structures and preparing themselves.
The occurrence of natural disasters often brings huge losses. Natural disasters are often caused by the continuous destruction of the environment by human beings. First of all, the huge and unscrupulous deforestation and reduction of forests have caused many natural problems, such as soil erosion, desertification and sandstorm.
It is necessary for human beings to protect the forest environment and prevent the occurrence of many natural disasters, With the development of industry, a large number of harmful gas emissions, leading to the decline of air quality, global warming, atmospheric loopholes, and even acid rain. Human beings should prevent the disorderly emission of harmful gases and protect the air. Before the occurrence of natural disasters, human beings always seem to be very small.
Therefore, I think that human beings should protect the natural environment, so as to reduce the occurrence of natural disasters, but also to improve The early warning ability of human beings to natural disasters can reduce human losses in the face of natural disasters.
