Upgrading of Computer Facility for Research in Seismology

0214069 Ekstrom该赠款提供支持，以升级哈佛地震计算设施，以促进地震学和地球物理学的广泛研究。升级将包括一个快速的多处理器服务器，具有大共享内存和大容量快速访问磁盘阵列。新基础设施支持的活动包括围绕哈佛CMT项目进行的地震研究。 该项目的一个重要组成部分是利用分布在全球各地的地震仪的数字数据，对世界各地震级大于约5.2级的所有地震进行系统分析。 所支助活动的第二个组成部分涉及地球内部弹性特性的成像。这项研究是通过开发新的数据集和联合反演各种现有的数据集，如绝对和差分旅行时间，面波频散曲线，全波形，和正常模式的频谱。 升级后的计算机设施将使人们能够对地球结构进行更详细的参数化，并对地球内部进行更逼真的成像。

0214069EkstromThis grant provides support to upgrade the Harvard Seismology computing facility in order to facilitate a broad range of research in seismology and geophysics. The upgrade will include a fast multiprocessor server with large shared memory and a large-volume fast-access disk array. The activities supported by the new infrastructure include earthquake studies focused around the Harvard CMT project. An important component of this project is the systematic analysis of all earthquakes with magnitudes greater than approximately 5.2 around the world, using digital data from globally distributed seismographs. A second component of the supported activities involves imaging of the elastic properties of the Earth's interior. This research 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. The upgraded computer facilities will allow a more detailed parameterization of Earth structure and a higher fidelity imaging of the Earth's interior.***
