【摘要】 利用不同时间尺度、不同震级下限的资料,分析了江西北部及邻区的地震活动时空分布特点。结果显示:本区地震活动成组现象明显,中强地震前中短期阶段的地震学异常特征主要表现为地震空区、地震条带或中等地震集中增强区。未来数年内本区还有可能发生中强地震,目前应当高度重视区域的震情发展趋势。更多还原

【Abstract】 Based on the data of different time scales and lower limit magnitudes,the paper analyzes the temporal/spatial distribution characteristics of seismic activities in the north of Jiangxi Province and the adjacent regions.The analysis results show that the seismic activities are obviously in groups;and that the seismological anomaly at short and intermediate period before the moderate-strong earthquakes mainly include the seismic gap,seismic belt or area with centralized/increased moderate earthquakes.The moderate-strong earthquakes may possibly occur in this region in the next few years,so it is highly important to attach great importance to the seisimic status and developments in this region.更多还原
