摘要
辽宁省康平地区近年来天然地震与非天然地震活动有所起伏,引起社会极大关注。利用辽宁区域台网记录到的地震事件波形,基于Brune震源模型,计算了5次显著的矿震震源参数,量化评估震源破裂的尺度和震源区视应力状态,对深入研究矿震的破裂特征和危险性评估提供了一定的依据。
Natural and unnatural seismic activity in the Kangping area of Liaoning Province has fluctuated in recent years,causing great concern in society.In this paper,using the waveforms of seismic events re-corded by the Liaoning regional station network and based on the Brune source model,we calculated the source parameters of five significant mining earthquakes to quantitatively assess the scale of source rupture and the apparent stress state of the source area,which provides some basis for an in-depth study of the rup-ture characteristics and hazard assessment of mining earthquakes.
