DziewonskiEAR-0207608该项目的主要目标是系统调查全球地震活动和绘制地球内部的三维绘图。地震研究主要围绕哈佛 CMT 项目进行。使用来自全球分布的地震仪的数字数据分析所有震级大于约 5.2 级的地震的震源机制。详细研究了不寻常的地震现象,例如慢震、火山崩塌和不明地震信号。结果通过电子邮件和哈佛地震学网页传播:http://www.seismology.harvard.edu。地球内部弹性特性的成像是通过开发新数据集和联合反演各种现有数据集(例如绝对和微分走时、表面波色散曲线、全波形和简正模谱)来实现的。 在模型参数化和反演中特别考虑了各向异性(径向、方位和一般)的包含。 模型和派生数据集可在研究人员的网站上找到。--
英文摘要
DziewonskiEAR-0207608The principal objectives of this project are the systematic investigation of global seismicity and the three-dimensional mapping of the Earth's interior. The earthquake studies are focused around the Harvard CMT project. All earthquakes with magnitudes greater than approximately 5.2 are analyzed for their source mechanisms using digital data from globally distributed seismographs. Unusual seismic phenomena, such as slow earthquakes, volcanic collapses, and unidentified seismic signals, are investigated in detail. Results are disseminated using electronic mail and the Harvard Seismology web page: http://www.seismology.harvard.edu. The imaging of the elastic properties of the Earth's interior is pursued by development of new data sets and the joint inversion of various existing data sets, such as absolute and differential travel times, surface-wave dispersion curves, full waveforms, and normal-mode spectra. Particular consideration is given to the inclusion of anisotropy (radial, azimuthal, and general) in the model parameterization and inversion. Models and derived data sets are available on the investigators' web site.--
