Earthquake Hazard and Neotectonics in Eastern China and Eastern United States

中国东部是一个地震活跃的板间环境，有大量的地震、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和新构造进行多目标比较研究，并参考加利福尼亚州的块体旋转，主要针对板内区的地震危险性和新构造问题。该项目是与北京国家地震局分析预测中心马宗晋一行合作完成的，并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应研究所进行为期一个月的访问。比较研究将涉及广泛交流地震数据、方法、结果和想法。我们将通过应用从烈度数据获得震中和震级的算法，通过由中等规模地震的波形模拟确定震源参数，通过绘制锡的传播特征图，来产生关于中国东北部地震活动的新数据。

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.
