Abstract:The crux of rapid reports of earthquakes is to establish three factors of the event as soon as possible.Seismic phase analysis is the basic work of earthquake monitoring, yet all types of seismic phase demand correct interpretation to determine the earthquake epicenter within the network.Summarizing rapid treatment methods can improve seismic phase analysis and the speed of issuing the rapid report.The present situation of rapid reports of earthquakes in Jiangsu province is analyzed from the viewpoint of both science and society, with recognition of its development.On this basis and using waveform data recorded by the Jiangsu digital seismic network, we studied the difference between natural earthquakes and explosions by contrasted comparative analysis of the waveform, amplitude, frequency spectrum, and other aspects, and found a difference between earthquakes and explosions, both in Jiangsu and adjacent areas.These methods, applied to digital seismograph network practice, can quickly and effectively differentiate natural events from artificial explosions.As a quick distinguishing method, it represents a swift and proficient application during major earthquakes, which provides a reliable basis for the identification of future phases.
