Abstract9987791A magnitude 7.4 earthquake occurred on August 17, 1999 in the area of Izmit, Turkey, 60 km to the east of Istanbul, 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 14-member 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.

1999年8月17日，土耳其伊斯坦布尔以东60公里处的伊兹米特地区发生了7.4级地震，造成了广泛的破坏、人员伤亡。 这次地震发生在沿着北安纳托利亚断层，这是一个走滑断层，与加州的圣安德烈亚斯断层有许多相似之处。这一行动为地震后不久派出的14人侦察队提供了部分支持，该侦察队尽可能详细地记录了这次地震的岩土工程、工程地质/地震学和海啸特征。 该小组与来自土耳其、日本和美国的其他侦察小组协调，与所有地震后侦察调查一样，预计土耳其这次地震将提供重要记录和数据。 从科学的角度来看，这些大地震是一个全面的实验，无法通过实验室或现场的控制实验来复制。 正是通过快速反应的侦察工作，这些事件的大多数短暂的数据可以恢复和用于进一步推进减轻地震灾害。 这项研究的结果有望产生信息和数据，这将有助于该专业了解大规模走滑断层系统对城市化和工业区的影响。这是一个涉及加州大学伯克利分校和南加州大学的多机构奖项。
