2013年4月20日，青藏高原东部龙门山断裂南段发生庐山7.0级地震，震源为中国。地壳中的剪切波分裂反映了龙门山断裂带地壳主压应力方向与断裂方向之间的联系。我们对庐山地震余震的定位分析表明，庐山7.0级地震的破裂带位置与汶川8.0级地震的破裂带位置有差距。我们认为，在不久的将来，应监测破裂缝隙及其附近地壳中的应力水平。为此，我们建议使用受控震源钻孔测量。
On April 20, 2013, the Lushan Ms7.0 earthquake struck at the southern part of the Longmenshan fault in the eastern Tibetan Plateau, China. The shear-wave splitting in the crust indicates a connection between the direction of the principal crustal compressive stress and the fault orientation in the Longmenshan fault zone. Our relocation analysis of the aftershocks of the Lushan earthquake shows a gap between the location of the rupture zone of the Lushan Ms7.0 earthquake and that of the rupture zone of the Wenchuan Ms8.0 earthquake. We believe that stress levels in the crust at the rupture gap and its vicinity should be monitored in the immediate future. We suggest using controlled source borehole measurements for this purpose.
