Based on the earthquakes recorded by Gansu early warning system since its operation and the output results of early warning system, a comparative study is conducted on the output magnitude of earthquake early warning system and the officially cataloged magnitude, and the distribution of magnitude errors is analyzed. We use the back-propagation neural network to learn and predict the warning magnitude parameters, and obtain the warning magnitude. The results indicate that for earthquakes with smaller actual magnitudes, the estimated magnitude is larger, while for earthquakes with larger magnitudes, the estimated magnitude is smaller. The neural network propagation algorithms can simulate and predict warning magnitude, and reduce the deviation between warning magnitude and cataloged magnitude.
