In this paper

39 small seismic swarms occurring in Shandong Province and its nearby ocean floor during the past more than 30 years were classified and analyzed systematically.The results show that the 39 small seismic swarms mostly distributed on seismic faults

67% of which took place on the jointing parts of 2 or more faults.86.5% of the faults

where small seismic swarms are easily be triggered

are active strike slip faults.57% of the small seismic swarms are of the mainshock-aftershock type

32% of them are of the double-shock type

and 11% of them

the multiple-shock type.56% of the cases in which a small seismic swarm event in the above region correspond to an earthquake of moderate

or strong

intensity in the periphery region.Among the remarkable small seismic swarms

the corresponding rate is 71%.Parameters of the remarkable seismic swarms are analyzed in this paper.
