摘要
通过对伊朗1990年6月21日鲁德巴尔地震的现场考察,初步确定该地震序列为主、余震型序列,余震大致呈北西南东分布,约为北西40°。震区的地表地震变形主要表现为地震破裂、滑坡和地震断层三种形式。由于建筑质量低劣和建筑物场地不利,造成构筑物的大量破坏,也是造成人员较大伤亡的主要原因。
Based on the field investigation of the Rudbar earthquake, June 21, 1990, Iran, the mainshock-aftershock type of the earthquake sequence is determined. The aftershock distribution is roughly in NW 40°direction. The Surficial deformation caused by the earthquake is mainly expressed as earthquake fractures, landslides and earthquake faulting.Owing to the inferior constructive quality and unfavourable site conditions buildings and structures were severely damaged, that is the main cause for a large number of casualties.
