【摘要】 通过分析1905年以来东北及邻近地区深震(mB≥6.0)及浅震(MS≥5.0)活动特征,研究深震、浅震"强震组"的时空相关性,计算二者能量比,认为东北地区已经进入第5活动期尾声,未来1—3年内,发生MS 5.0以上地震的可能性不大。更多还原

【Abstract】 Through the analysis of deep earthquake since 1905 in the northeast and adjacent areas(mb≥ 6.0)and characteristics of shallow earthquake(MS≥ 5.0) activities, study the earthquake depth"strong earthquake group"of time and space relevance, calculation depth/shallow seismic energy ratio. The results show that earthquakes active in Northeast China and adjacent areas coming to an end. In the next 1-3 years, shallow earthquakes with magnitude more 5 occur unlikely in Northeast China and adjacent areas.更多还原
