Abstract

Abstract:

The frequency of earthquakes in the Three Gorges Reservoir has increased significantly since the first water storage of the Three Gorges Reservoir in 2003. Four earthquakes above M4.0 occurred in 2017 and 2018, and the largest earthquake was the M4.5 earthquake on October 11, 2018. All four earthquakes were located on the north bank of the reservoir, about 2km away from the shore. The number of earthquakes omitted from the manual catalog in the Three Gorges reservoir area is high, and the completeness of the earthquake catalog is poor, which limits the understanding of the earthquake genesis mechanism in the reservoir area. To gain a deeper understanding of this earthquake sequence, this article utilizes continuous waveform data from 12 fixed stations of the Three Gorges Network, employing the PALM algorithm to obtain high-resolution earthquake catalogs for two earthquake sequences. It then discusses their causes.

The analysis shows that the PALM catalog is 3-4 times larger than the manual catalog, and the mean value of the difference between the epicenters of the two catalogs is 0.57km, the mean value of the difference between the moments of onset of the earthquakes is -0.43s, and the mean value of the difference between the magnitudes of the earthquakes is 0.04. The earthquake precise positioning results show the aftershock epicenters of the 2017 M4.3 and M4.1 earthquakes are mainly spread along two approximately orthogonal directions, NE and NW; the NE-oriented profiles show that the depth of the epicenters is in the range of 3~5km in general, with certain wave-like undulation characteristics; the NW-oriented profiles show the characteristics of being shallow on the SE side, and deeper on the NW side, with a slight fluctuation in the middle. All of them have no obvious tendency behaviors. The epicenters of the aftershocks of the 2018 M4.5 and M4.1 earthquakes are mainly distributed along the SWW direction, and remain more discrete in the NW direction. The depth of the earthquake source is generally characterized by SW shallow NE deep, and the aftershocks are mainly distributed at a depth of 5.0~7.0km, showing a narrow linear band structure. The seismogenic fault of the 2018 Badong earthquake sequence was high-angle west-dipping, and the distribution of earthquake sources was relatively more concentrated.

According to the regional geological structure, the main shock and most of the aftershocks of the 2017 Badong earthquake sequence, which was in the period of low water level of the reservoir, were mainly concentrated in the Thick Layer Limestone of the Jialingjiang group, which is developed by joint fissures at a depth of about 5km, and the limestone are susceptible to destabilizing sliding due to the long-term dissolving and eroding action of the groundwater, and a few of the aftershocks were distributed in the strata of the second, third, and fourth sections of the middle Triassic Badong group, and the stratigraphy of the second and fourth segments of the Badong group is characterized by the purple-red siltstone and gray-green mudstone interbedded as a characteristic, the stratigraphy of the third section of the Badong group is dominated by gray and light gray-green graystone and marl, which is easy to be weakened and softened to produce unstable sliding under the erosive action of groundwater. While the 2018 Badong earthquake sequence is in the period of high water level, most of the aftershocks are mainly concentrated in the Permian System geological formation around 7km, and the earthquake sequence migrated upward to a depth of 5km without continuing to expand, and it is speculated that the 2018 Badong earthquake sequence may have been prevented from continuing to migrate upward by the slip surface. The 2017 M4.3 earthquake caused the expansion of some rifts, and the effects of reservoir water erosion and dissolution on earthquake activity gradually increased, especially in the Limestone zone, where the reservoir water continued to dissolve along the original or newborn rifts for a long time, causing the continuous expansion of pore space, and the highly permeable flow channels transported fluids from the existing rift network to the faults, which contributed to the occurrence of the 2018 Badong M4.5 earthquake and the earthquake sequence became a linear belt-like structure.

The analysis suggests that the occurrence of the 2017 Badong M4.3 earthquake is related to the slip-fold tectonics, which is a earthquake activity that occurs in the wings of the fold tectonics, and the rest of the earthquakes are mainly distributed in the slip layer, with fewer earthquakes close to the nucleus of the dorsal folds and more earthquakes in the two flanks. The 2018 Badong M4.5 and M4.1 earthquake sequences were about 1.0km in length, SWW in strike and NW in tendency, with a narrow distribution of earthquakes and no migratory features, showing a narrow band structure. The fracture zones with high permeability acted as a fluid pathway. The injection of fluid into the faults resulted in the unstable sliding of the faults with the change of the pore pressures. The slipping layer above the aftershock sequences prevented the earthquakes from continuing to migrate upwards.

摘要：

三峡库区于2017年和2018年先后发生4次M4.0以上地震。文中使用三峡台网12个固定台的连续波形数据, 利用PALM算法获得了2次地震序列的高分辨率地震目录。将PALM目录结果与人工目录进行对比分析, 结果表明, 所获得的地震数量比人工目录多3~4倍, 震中差异平均值为0.57km, 发震时刻差异平均值为-0.43s, 震级差异平均值为0.04。2017年M4.3和M4.1地震发生在低水位期, 序列主要沿NE和NW 2个方向展布, 余震主要分布在3.0~5.0km深度, 且主要分布于滑脱层中, 靠近背斜褶皱核部地震较少, 而两翼地震较多。2018年M4.5和M4.1地震发生在高水位期, 序列主要分布在SWW走向、 NW倾向的断裂上, 余震主要分布在5.0~7.0km深度处, 呈线性分布, 地震活动宽度很窄且没有扩张的迹象, 渗透率较高的破坏带充当流体通道, 流体注入断层导致孔隙压力变大使断层失稳滑动, 余震序列上方的滑脱面阻碍余震继续向上迁移。
