Exploration and practice of integrated construction of meteorological risk warning for geological hazards in Zhejiang Province

Abstract

Geological hazard forecasting and early warning are crucial measures for preventing geological disasters and minimizing casualties. Since the initiation of geological hazard meteorological risk early warning in 2003, 80% of mountainous provinces, cities and counties in China have implemented such measures. However, the independent construction model at the provincial, city, and county levels is inadequate to meet the collaborative needs across ministries, provinces, and the integration of cities and counties. This paper presents the case of integrated construction of meteorological risk early warning for geological hazards in Zhejiang Province. Following the principle of “provincial forecast extends to county, municipal forecast to township, and county early warning to village (point)”, the integration and exploration of trend forecasting, daily forecasting, short-term forecasting, real-time early warning, and the ‘intelligent prevention of geological disaster’ app have been conducted. A full lifecycle control and prevention business system of geological disaster with visual supervision and closed-loop means of intelligent prevention of geological disaster APP application has been established. Additionally, a digital product system for geological hazard prediction and early warning, tailored to the characteristics of Zhejiang Province, has been developed.
