Prevention and control measures such as earthquake, debris flow, landslide, typhoon, cold wave, drought, flood, insect pest and rat damage.

For earthquake, debris flow, landslide, typhoon, drought, flood and other climatic and geological disasters, except debris flow and landslide will be affected by soil erosion, it is basically impossible to prevent them. We can plant more trees to reduce the probability of disasters, but the hidden dangers of geological structures are really difficult to eliminate. Floods can be prevented from some water conservancy facilities, such as reservoirs and dams. Pests and rodents are caused by the imbalance of biological systems, and rodents are also prevented from these aspects because of environmental factors. For some disasters, we can't prevent them, but we can do some effective measures to reduce the losses caused by disasters when and after they happen.
