How is the warning signal of mountain torrents spread?

The early warning of mountain torrents refers to a kind of disaster prevention and mitigation work that uses modern communication means to send early warning information to the surrounding people in time and guide them to take emergency measures in time, thus reducing casualties and property losses. Flash flood warning is issued by means of satellite, 3G/4G/5G, microwave, satellite communication and short wave communication. The general procedure and way to do a good job in early warning and signal transmission of mountain torrents is that the county flood control and drought relief headquarters will notify the township (town) flood control headquarters through television, telephone, fax and SMS after receiving the rain and water information from the hydrological and meteorological departments. The township (town) flood control headquarters should immediately notify the early warning information to the villages and groups, and monitor the patrols in the villages 24 hours a day during the early warning period, and immediately send out an alarm signal if any danger is found. In case of emergency, villages and groups can report directly to the county flood control and drought relief headquarters, and the upstream village will transmit the information of water and rain to the downstream village, and the county flood control and drought relief headquarters will command the flood control and disaster relief work in a unified way.
