Abstract: Note-taking articles, Sanyi Sketch, Huaicheng Night Talk, and Yeyu Unofficial History, are contained in the book of Some Lost Ancient Books in Dali. They describe that Mr. Fa Duan, Mr. Guang Ming and Mr. Yang Jinghao had forecasted, predicted and prevented earthquakes in Dali in the year of 779, 1111 and 1341, just according to some macroscopic anomalies. The earthquake with more macroscopic precursor phenomena can be forecasted, predicted and prevented. However, it is necessary to strengthen the research on the mechanism of macro-precursors, to reveal the physical essence of macroscopic precursor phenomena, to produce a high-sensitivity, high-resolution and high-precision earthquake precursor monitoring instrument which can effectively catch the macroscopic precursor phenomena before earthquakes, to carefully design and place on the monitoring grid points. Then we can achieve real-time the continuously monitored various signals which are sented through the network to the seismic monitoring center, analyse the signals by high-speed computer networks and cloud platforms, and collect reliable earthquake precursor information. Finally, the earthquake forecast, prediction and prevention is expected to achieve with the modern seismic monitoring network.
