Abstract: | Diexi earthquake (M7. 5) in 1933 is a great event that occurred at the east border of Qinghai-Xizang Plateau in the 20th century. There are obviously different opinions about the shape of isoseismal lines and the genetic fault of this earthquake. Based on the study of the newly found north-south trending active fault and ground fissures of Diexi earthquake, this paper tends to hold that, as the southward extension of Minjiang fault, this north-south trending active fault might be the genetic fault of this event. |
