Abstract：This paper discussed the decisive factors affecting the ability of earth-quake early warning.Based on the distribution of existing seismic networks, data transmission delay and network running state,we analyzed whether they meet the needs for earthquake early warning,and made corresponding recom-mendations in order to improve the situation.Results show that the status quo of China earthquake networks did not meet the needs for earthquake early warn-ing.Therefore,besides raising the network density and its operation rate,we should upgrade the existing seismic data acquisition system and real-time trans-mission software so as to satisfy the data transmission demand for earthquake early warning.
