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3点27分（当地时间），宾格尔以北10公里处发生了6.4级地震（美国地质勘探局和韩国电力公司）。地震震中位于北纬38.94-东经40.51（ERD-Ankara）。据估计，地震深度为6公里。最强烈的地震记录在宾格尔。这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）。强震持续时间为17 s。地震后，12栋建筑物倒塌，13栋建筑物严重受损。另据报告，几座桥梁似乎已被摧毁，有待核实。官方公布的死亡和受伤人数分别为105人和600人。该小组的主要目标是记录：（a）钢筋混凝土框架建筑物和纪念碑的损坏情况，（B）桥梁结构的损坏情况，以及（c）事件的岩土工程和地质方面。 根据我们在1999年土耳其马尔马拉和杜兹切地震后的经验，我们知道记录在地面运动中幸存下来的结构的属性与记录受损建筑物的属性一样重要。因此，我们打算利用我们在宾格尔的时间，不仅记录受损的，而且记录未受损的结构。我们还计划利用Bingol的数据来扩大我们的数据库（anatolianquake.org），并测试和改进为评估地震脆弱性而开发的方法。 重要性：建议以尽可能精确的形式收集和记录与Bingol事件有关的科学易腐数据，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将有助于美国、土耳其和世界其他地震区的减灾工作。特别是，从4-5层钢筋混凝土结构的性能中可以获得大量的知识。这种结构在美国的中西部和东部比比皆是。此外，重要的是记录桥梁性能，以帮助规范开发人员和工程师处理美国桥梁的抗震升级。此外，该调查建议与METU的研究人员密切合作，以促进土耳其和美国在地震工程领域的合作活动。 为此，我们请求提供28 202.00美元，用于一个由8名成员组成的小组的旅费和其他有关费用。
