摘　　要：1933年叠溪75级地震是发生在青藏高原东南缘的重大事件。对这次地震的等烈度线形态及与之相关的发震构造的认识有着明显的分歧。本文基于野外新发现的南北向活动断裂以及叠溪地震地面破裂的研究。Diexi earthquake ( M 7 5) in 1933 was a great event at the eastern border of Qinghai\|Xizang Plateau in this century.There are obviously different opinions about the shape of isoseismic lines and genetic fault for this earthquake.According to the discussion of newly found north\|south trending active fault and ground fractures of Diexi earthquake,this paper inclined to consider that the north\|south trending active fault which might be the south extending of Minjiang fault is the most candidate for the genetic fault of the event.
