Based on the data of different
time scales and lower limit magnitudes, this paper analyzes the
temporal/spatial distribution characteristics of seismic activities in the
north of Jiangxi Province and its adjacent regions. The 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, so it is highly important to attach great importance to the seismic
status and developments in this region.
