Earthquake Hazard and Neotectonics in Eastern China and Eastern United States

中国东部是一个地震活跃的板块间环境，具有丰富的地震、构造和地球物理资料。我们建议对中国东部和美国东部的地震活动性和新构造进行多目的比较研究，并参考加利福尼亚州的块体旋转，主要针对板内地区的地震危险性和新构造问题。本项目由北京国家地震局分析预报中心的马宗金及其团队合作完成，已获得国家地震局批准。该项目包括每个合作小组每年对对口研究所进行为期一个月的访问。比较研究将涉及地震数据、方法、结果和思想的广泛交流。我们将通过应用从烈度数据获取震中和震级的算法，通过中等规模地震的波形建模确定震源参数，以及通过绘制Sn传播特征来获得中国东北地震活动性的新数据。

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.
