| 摘 要： | IntroductionIt is an important approach to research on earthquake phenomena, an elemental portion of seismology, for understanding seismic activities. Aim of seismic pattern procession is to research spatial-temporal distribution of epicenters and generalize saliently seismic characteristics, to explore the regularities of seismicity and earthquake mechanism. People acquaint earthquake phenomena gradually with development of observation technique. Initially we could only feel and record destru…

| Abstract: | Analysis of seismic data and seismicity characteristics in China, we gave a method to deal with seismic patterns by calculating density at grid nodes. Number of earthquakes and epicenter distribution are considered comprehensively in this method. Effect of datum accuracy is stressed on parameter confirmation. Seismic patterns from this method are stable and can reflect seismic characteristics reliably. These seismic patterns are the base of quantitative analysis of seismicity. It can be applied in seismic tendency analysis and medium-long term earthquake prediction, earthquake countermeasure and risk mitigation. |
