US-Turkey Workshop on the Izmit Earthquake, American Geophysical Union Meeting; San Francisco, California, December 13-17, 1999

9912582 ReilingerDescription：该奖项旨在支持来自土耳其的8名科学家参加1999年12月13日至17日在旧金山举行的美国地球物理联合会1999年秋季会议。会议将专门讨论1999年8月17日土耳其伊兹米特发生的里氏7.4级地震。这次会议是由麻省理工学院地球、大气和行星科学系的罗伯特·赖林格博士组织的。会议的目的是交换土耳其和美国科学家在那次强烈地震后几天收集的数据和其他信息。地震发生后，P.I.S团队在国家科学基金会/EAR提供的赠款下，立即在土耳其获得了重要数据。地球物理学界对这场地震特别感兴趣，因为它代表了本世纪沿北安纳托利亚断层(NAF)从东向西连续破裂的一系列地震中的最新一次。这一系列地震的地表偏移量已经有了很好的记录，并提供了大量关于连续地震相互作用的信息，这与一般的地震过程和伊斯坦布尔地区的地震危险研究有关。此外，伊兹米特地震发生在一个正在通过全球定位系统观测进行详细监测的地区。这些大地测量观测提供了有关地震前、同震和震后形变的新信息。这些信息将加强我们对整个地震周期的机制的理解。特别是，由于NaF和圣安德烈亚斯断层之间的相似之处，从伊兹米特地震中获得的信息将有助于我们了解圣安德烈亚斯和其他大陆转换断层沿线的地震过程。范围：该项目将支持来自土耳其的关键科学家参加一次重要会议，该会议旨在了解1999年土耳其大地震中收集的现场数据的结果，他们积极参与使用GPS地面运动测量进行的地震研究。他们的参与应有助于改进对所取得的结果和即将得出的结论的解释。这些科学家的出席将有助于美国地质学家和地球物理学家未来在这一领域的研究，并将增强进一步合作的潜力。因此，土耳其科学家的参与将对所有参与这些研究和今后努力的人都有好处。该项目完全符合国际方案司的目标，即促进与外国交换重要的科学数据，并加强互利的国际合作。

9912582ReilingerDescription: This award is to support the participation of eight scientists from Turkey in the Fall 1999 Meeting of the American Geophysics Union in San Francisco, December 13-17, 1999. The meeting will have a session devoted to the August 17, 1999 earthquake centered in Izmit, Turkey, and measuring 7.4 on the Richter scale. The session is organized by Dr. Robert Reilinger of the Earth, Atmosphere, and Planetary Sciences Department at M.I.T. The purpose of the session is to exchange data and other information gathered by Turkish and US scientists in the days following that strong quake. Significant data was obtained in Turkey by the P.I.'s team, under a grant made by NSF/EAR, immediately following the quake. This earthquake is of special interest to the geophysical community because it represents the latest in a series of earthquakes in this century that ruptured sequentially from east to west along the entire length of the North Anatolian fault (NAF). The surface offsets for this sequence of earthquakes has been well documented and has provided a wealth of information on the interaction of sequential earthquakes, which has relevance to earthquake processes in general, and to seismic hazard studies in the Istanbul region. Furthermore, the Izmit earthquake occurred in an area that is being monitored in detail with Global Positioning System observations. These geodetic observations are providing new information on pre-, co-, and post-seismic deformation. This information will enhance our understanding of the mechanics of the entire earthquake cycle. In particular, and because of the similarities between the NAF and the San Andreas fault, the information gained from the Izmit earthquake will aid our understanding of earthquake processes along the San Andreas and other continental transform faults.Scope: This project will support participation by key scientists from Turkey, who are actively involved in seismic studies using GPS measurements of ground movement, in an important meeting intended to understand the results from field data collected in the major earthquake of 1999 in Turkey. Their participation should lead to improvement in the interpretation of the results obtained and in the conclusions to be reached. The attendance by these scientists should help US geologists and geophysicists with their future research in this field, and would enhance the potential for further collaboration. The participation of the Turkish scientists will therefore have mutual benefits to all involved in these studies and for future efforts. The project fits well within the objectives of the Division of International Programs for facilitating the exchange of important scientific data with foreign countries, and for enhancing mutually beneficial international collaboration.
