英文摘要July 4-6, 2019, located near Ridgecrest, Southern California, USA, a series of earthquakes occurred in less than two days, including the strong earthquakes M(w)6. 4 and M(w)7. 1. Two days after the earthquakes, the field geological survey and measurement of the surface ruptures in the epicenter area were carried out. Two fracture zones in 50 km length in NW direction and 10 km length in NE direction have been discovered after a series of Ridgecrest earthquakes. According to the field investigation, the dextral strike slip of surface ruptures in NW direction is produced by the Mw7. 1 earthquake, while the sinistral strike slip of surface ruptures in NE direction is produced by the M(w)6. 4 earthquake. Combining with statistical analysis of earthquake sequence, it's found that NW is the main direction fracture zones of this earthquake sequence and most of the earthquake energy is released. Based on the analysis of time series of earthquakes and dense strip distribution of earthquake sequences, it can be inferred that the earthquake is a group of complex conjugate earthquakes caused by the rupture of two conjugate faults in NE and NW directions. It also can be speculated that the 1\4(w)6. 4 earthquake is the strong foreshock, which promotes the occurrence of M(w)7. 1 earthquake.
