Abstract: At present, Hebei Earthquake Early Warning system has two systems, JEEW and EEW. The logs produced by the two systems have no parameter description, which is not convenient for analysis and processing. The Earthquake early warning log analysis system adopts B/S architecture, which can analyze the log information produced by the two Earthquake Early Warning systems. The early warning log analysis system adopts B/S structure, which can analyze and process the log information produced by the two Earthquake Early Warning systems, visualize the information in the log with tables and maps, clearly and intuitively see the data change process in the output process of early warning results. It can also compare the early warning information with the result of rapid report, so as to improve early warning log using value.
