Earthquakes are one of the most frequent and most serious natural disasters in the world, and are a major global problem facing the survival and development of mankind today. Earthquake disasters have the following prominent characteristics:

• Great destructiveness. Earthquakes can cause damage to mountains, ground and its attachments (such as vegetation and buildings), and are often accompanied by secondary disasters such as tsunamis, fires, landslides, and floods, which can cause a large number of casualties and property losses. They will also bring new disasters to modern social economy and technology, such as communication accidents and computer accidents.

• Instantaneousness and unpredictability. Earthquakes occur in an instant, and the duration of earthquake action is very short, ranging from a dozen seconds at the shortest to two or three minutes at the longest, causing landslides and collapses of houses. People cannot organize effective defense actions in a short period of time. At present and for a long time to come, the level of science and technology is still unable to predict the arrival of earthquakes.

• Frequency. There are about 5 million earthquakes on the earth every year, that is, tens of thousands of earthquakes every day. Most of them are too small or too far away for people to feel. There are about a dozen or twenty earthquakes that can really cause serious harm to humans, and there are about one or two earthquakes that can cause particularly serious disasters.

  Earthquakes have many impacts on the economy and society. From a macro perspective, on the one hand, sudden natural disasters such as earthquakes will seriously damage the infrastructure and buildings in the affected areas, and may cause a large number of casualties, bringing negative impacts on local economic development; but on the other hand, the damage to buildings caused by natural disasters provides an opportunity for urban buildings to upgrade and seek new development, clearing the contradiction between land redevelopment and durable buildings in urban development, and also providing new impetus for local economic development. From a micro perspective, the huge damage caused by natural disasters will cause local governments to face huge financial pressure in the short term in post-disaster rescue and reconstruction, which may lead to local governments strengthening tax collection and management of enterprises within their jurisdiction to obtain fiscal revenue, which will also have a direct impact on enterprises.
