Types of earthquake prediction

According to the stages of earthquake preparation, the earthquake analysis and prediction work in China summarized the scientific ideas and working procedures of long-term, medium-term, short-term and imminent gradual tracking and prediction. Earthquake prediction adheres to the realization of strong earthquake prediction, time tracking prediction and location shrinkage prediction. Classification mainly includes the following categories:

1. Long-term prediction: refers to the prediction of the area and intensity where destructive earthquakes may occur in the future 10. Mainly to determine the key monitoring and defense areas for earthquakes.

2. Medium-term prediction: refers to the prediction of the area and intensity where destructive earthquakes may occur in the next year or two. It mainly provides scientific basis for the local government to deploy earthquake prevention and disaster reduction work.

3. Short-term prediction: refers to the prediction of the time, place and magnitude of the earthquake that will occur within three months. It mainly provides scientific basis for the local government to deploy earthquake emergency work.

4. Impending earthquake prediction: refers to the prediction of the time, place and magnitude of the earthquake that will occur in 10 days. Directly serve earthquake emergency and disaster relief, and reduce casualties and economic losses.

5. Post-earthquake trend judgment: refers to the analysis results of the recent seismic activity situation that has an impact on society after the earthquake.
