【摘要】 概述了非天然地震的范畴、广东非天然地震的类型。通过对非天然地震事件和天然地震的震相分析、统计计算、分析研究得出广东非天然地震的一些规律与特征,如非天然地震的振幅比AS/AP和波的持续时间τ值比天然地震小,发震时间比较规律等,讨论了非天然地震的识别方法。更多还原

【Abstract】 The category of non-natural earthquake and its types in Guangdong were summarizec. Some rules and characteristics of non-natural earthquake in Guangdong were gained by the seismic phase analysis, statistic and account for non-natural and natural earthquakes.For instance, amplitude ratio A_S/A_P of non-natural earthquake and its wave continuance time τwere smaller than natural earthquakes,and its origintimes were more disciplmarian.Meanwhile, identifying methods of non-natural earthquake were discussed.更多还原
