Eastern China is a seismically active interplate environment for which extensive sets of seismic, structural and geophysical data are available. We propose a multipurpose comparative study of seismicity and neotectonics in eastern China and in the eastern United States with reference also to block rotation in California, primarily directed at problems concerning earthquake hazard and neotectonics in intraplate regions. This project is in collaboration with Ma Zongjin and his group at the Center for Analysis and Prediction, State Seismological Bureau, in Beijing, and has been approved by the State Seismological Bureau. The project involves yearly one-month visits by each of the collaborating groups to the counterpart institutes. The comparative study will involve an extensive exchange of earthquake data, methodologies, results and ideas. We will produce new data on the seismicity of northeastern China by the application of an algorithm to obtain epicenters and magnitudes from intensity data, by the determination of source parameters from waveform modeling of moderate size earthquakes and by mapping Sn propagation characteristics.

中国东部是一个地震活跃的板间环境， 大量的地震、构造和地球物理数据， available. 我们提出了一个多目的的地震活动性比较研究 中国东部和美国东部的新构造运动， 也参考了加州的块旋转，主要针对 板内地震灾害与新构造问题 地区 这个项目是与马宗金和他的 国家地震分析和预测中心的一个小组 并已获国家地震局批准 局 该项目涉及每年由每一个 合作小组到对口机构。 比较 这项研究将涉及广泛地交换地震数据， 方法、结果和想法。 我们将提供新的数据， 中国东北地区的地震活动的算法应用， 从烈度数据中获得震中和震级， 从中等地震波的波形模拟确定震源参数 地震的大小和绘制Sn传播特征。
