9804780BarazangiThis research involves the one-year deployment of portable PASSCAL seismograph stations in eastern Turkey to investigate the Eurasian/Arabian plate margin across the Bitlis suture and East Anatolian Fault. The experiment and subsequent data analyses will be a joint, cooperative project between Cornell University and Turkish scientists from Kandilli Seismological Observatory. The methods used to study the data will include teleseismic and regional waveform modeling, travel-time tomography, hypocenter location inversion, and shear-wave splitting analysis. The results of applying these techniques to the broadband data will allow an inference of the rheology, thickness, and deformation of the Anatolian crust and lithosphere. One of the least understood processes within the framework of plate tectonics is the mechanism for continent-continent collision, yet this process plays a critical role in the development and growth of the continents on earth. This seismically active area generates considerable earthquake hazard. This research is a component of the National Earthquake Hazard Reduction Program.***

9804780 Barazangi这项研究涉及在土耳其东部部署便携式PASSCAL地震仪台站，以调查横跨Bitlis缝合线和东安纳托利亚断层的欧亚/阿拉伯板块边缘。该实验和随后的数据分析将是康奈尔大学和坎迪利地震观测站的土耳其科学家之间的联合合作项目。 用于研究数据的方法将包括地震和区域波形建模、走时层析成像、震源位置反演和剪切波分裂分析。 将这些技术应用于宽带数据的结果将允许推断安纳托利亚地壳和岩石圈的流变学，厚度和变形。 在板块构造的框架内，最不为人所知的过程之一是大陆-大陆碰撞的机制，但这一过程在地球上大陆的发展和生长中起着关键作用。这个地震活跃区产生相当大的地震危险。 这项研究是国家减少地震灾害计划的一个组成部分。
