摘要

我们考虑2015年9月2日,发生在北-木雅脊原震区的Mw=5.1 Tallay地震,该震区北部与木雅-宽达盆地相邻。本文介绍了这次地震事件的仪器和宏观地震资料。它的地震矩张量由表面波振幅谱计算。在贝加尔湖裂谷的东北侧获得了强地面运动的新数据。发现塔莱地震与裂谷应力场激活的二级多向断裂的发震更新有关。

THE SEPTEMBER 2, 2015, КR=14.0, Mw=5.1, I0=7–8 TALLAY EARTHQUAKE at the NORTH-EASTERN FLANK of the BAIKAL RIFT
We consider September 2, 2015, Mw=5.1 Tallay earthquake occurred in the previously aseismic area of the North-Muya Ridge adjoining to the Muya-Kuanda basin from the north. Instrumental and macroseismic data on this seismic event are presented. Its seismic moment tensor is calculated from surface wave amplitude spectra. New data on strong ground motions are obtained within the north-eastern flank of the Baikal rift. The Tallay earthquake is found to be connected with seismogenic renewal of the second-order multidirectional faults activated in the rift stress field.
