The earthquake of moment magnitude 6.4 (USGS and KOERI) occurred at 10 km north of Bingol at 03:27 am (local time) on 1 May 2003. The epicenter of the earthquake was at 38.94N- 40.51E (ERD-Ankara). The depth of the quake was estimated to be at 6 km. The strongest record of the earthquake was recorded at Bingol. The peak ground accelerations (PGA) of the three components of this record are 0.55g (NS), 0.28g (EW) and 0.47g (UP). The duration of the strong motion is 17 s. After the earthquake 12 buildings were collapsed and 13 buildings were damaged severely. It was also reported that several bridges appear to have been destroyed pending verification. The official numbers of fatalities and injuries were 105 and 600, respectively. The main objectives of the group are to document: (a) the damage to reinforced concrete frame buildings and monuments, (b) the damage to bridge structures, and (c) the geotechnical and geological aspects of the event. From our experience in connection with the aftermath of the 1999 Marmara and Duzce earthquakes in Turkey, we know that documenting the properties of the structures that survived the ground motion is as important as documenting the properties of the damaged buildings. Therefore, we intend to use our time in Bingol to document not only the damaged but also the undamaged structures. It is also our plan to use the data from Bingol to expand our database (anatolianquake.org) and to test and improve the methods developed for assessing earthquake vulnerability. Significance: The collection and recording of scientific perishable data related to the Bingol event in as precise form as possible is proposed so that this experience can be shared with interested engineers and scientists. It is hoped that the careful study of the data shall contribute to earthquake hazard mitigation efforts in the US, Turkey and other seismic regions of the world. In particular, there is a great deal of knowledge to be gained from the performance of 4-5 story reinforced concrete structures. Such structures abound in the Midwest and Eastern United States. Also, it is important to document the bridge performance to assist code developers and engineers dealing with seismic upgrading of bridges in the US. Furthermore, the investigation is proposed in close collaboration with researchers from METU, to promote cooperative activities between Turkey and the USA in the field of earthquake engineering. For this effort we are requesting $28,202.00 to cover travel and other related expenses for a team consisting of eight members.

2003 年 5 月 1 日凌晨 03:27（当地时间），在宾戈尔以北 10 公里处发生了 6.4 级地震（USGS 和 KOERI）。地震震中位于北纬 38.94 度至东经 40.51 度（ERD-安卡拉）。地震深度估计为6公里。宾戈尔记录了最强地震记录。该记录的三个分量的峰值地面加速度（PGA）分别为0.55g（NS）、0.28g（EW）和0.47g（UP）。强烈运动的持续时间为17秒。地震发生后，12栋建筑倒塌，13栋建筑严重受损。另据报道，几座桥梁似乎已被摧毁，有待核实。官方公布的死亡人数和受伤人数分别为 105 人和 600 人。该小组的主要目标是记录：(a) 对钢筋混凝土框架建筑物和纪念碑的损坏，(b) 对桥梁结构的损坏，以及 (c) 事件的岩土技术和地质方面。 根据我们在 1999 年土耳其马尔马拉和迪兹杰地震后的经验，我们知道记录在地震动中幸存的结构的特性与记录受损建筑物的特性同样重要。因此，我们打算利用在宾戈尔的时间不仅记录受损的结构，而且记录未受损的结构。我们还计划使用 Bingol 的数据来扩展我们的数据库 (anatolianquake.org)，并测试和改进为评估地震脆弱性而开发的方法。 意义：建议以尽可能精确的形式收集和记录与宾戈尔事件相关的科学易腐烂数据，以便与感兴趣的工程师和科学家分享这一经验。希望对这些数据的仔细研究能够为美国、土耳其和世界其他地震区的地震减灾工作做出贡献。特别是，可以从 4-5 层钢筋混凝土结构的性能中获得大量知识。这种结构在美国中西部和东部比比皆是。此外，记录桥梁性能对于帮助代码开发人员和工程师处理美国桥梁的抗震升级也很重要。此外，这项调查是与 METU 研究人员密切合作提出的，以促进土耳其和美国在地震工程领域的合作活动。 为此，我们请求 28,202.00 美元，用于支付由 8 名成员组成的团队的差旅费和其他相关费用。
