What does geological disaster early warning mean?
Early warning of geological disasters means that the risk of geological disasters within 24 hours is relatively high. The yellow warning signal of geological disasters is the first-level warning signal of geological disasters. Meteorological early warning and forecast information of geological disasters is released in the weather forecast program of CCTV and China Geological Environment Information Network from May to September every year, with the purpose of reminding cadres and masses in early warning areas to guard against landslides, collapses and mudslides.
Geological disasters come from the catastrophic damage of natural and man-made geological processes to the geological environment, mainly including collapse, landslide, debris flow, ground subsidence and ground fissures. China is one of the regions with frequent geological disasters in the world. In recent years, the study of landslide and debris flow disasters is a hot spot in the industry. The work of prevention and control of geological disasters is often scattered, which leads to poor standardization and difficult resource sharing.
