An Investigation of the Geotechnical Aspects of the November 12, 1999, Duzce, Turkey Earthquake - Preliminary Reconnaissance Effort

【摘要】1999年11月12日，土耳其达帕扎里以东70公里、安卡拉西北170公里处的杜兹-博卢地区发生7.2级地震，造成了广泛的破坏、人员伤亡和生命损失。这次地震发生在北安那托利亚断层，这是一条走滑断层，与加州的圣安德烈亚斯断层有很多相似之处。这一行动为在地震发生后不久派遣的勘察队提供了部分支持，勘察队将尽可能详细地记录这次地震的岩土、工程地质/地震学和海啸成因特征。这个小组与来自土耳其、日本和美国的其他侦察小组进行协调。与所有震后侦察调查一样，预计土耳其这次地震将提供重要的记录和数据。从科学的角度来看，这些大地震就像全面的实验，不能通过实验室或实地的控制实验来复制。正是通过快速反应侦察工作，才能从这些事件中恢复大部分短暂的数据，并将其用于进一步推进减轻地震危害的工作。这项调查的结果有望提供信息和数据，帮助专业人士了解大规模走滑断层系统对城市化和工业区的影响。这是一个多机构奖，涉及加州大学伯克利分校和南加州大学。

Abstract0083058A magnitude 7.2 earthquake occurred on November 12, 1999 in the area of Duzce-Bolu, Turkey, 70 km east of Adapazari and 170 km northwest of Ankara, resulting in extensive damage, injuries and loss of life. This earthquake occurred along the North Anatolian fault, a strike slip fault that has many similarities to the San Andreas fault in California.This action provides partial support for a reconnaissance team that was dispatched shortly after the earthquake to document the geotechnical, engineering geology/seismology, and tsunamigenic features of this earthquake in as much detail as possible. This team coordinated with other reconnaissance teams from Turkey, Japan and the United States.As with all post-earthquake reconnaissance investigations, it is expected that vital records and data will become available as a result of this earthquake in Turkey. From a scientific viewpoint, these large earthquakes act as full-scale experiments that cannot be duplicated via controlled experiments in the laboratory or in the field. It is through quick response reconnaissance efforts that the mostly-ephemeral data from these events can be recovered and used to further advances in earthquake hazard mitigation. The results from this investigation are expected to yield information and data that will help the profession to understand the effects of large-scale strike slip fault systems on urbanized and industrial areas.This is a multi-institutional award involving the University of California at Berkeley and the University of Southern California.
