Global Seismograph Network Improvements

该项目继续了美国地质调查局和美国国家科学基金会在全球地震学方面的联合合作，并在双方地震学谅解备忘录（MOU）的框架内进行。这项工作主要围绕开发和安装地震学联合研究机构（IRIS）数据收集中心，以及安装新的全球数字地震台站。美国地质调查局正在与美国国家科学基金会/IRIS合作开展这两方面的工作。

The project continues joint cooperation between the U.S. Geological Survey and the National Science Foundation in global seismology, and is conducted within the framework of their Memorandum of Understanding (MOU) in seismology. The work centers around the development and installation of the Incorporated Research Institutions for Seismology (IRIS) data collection center, and the installation of new global digital seismic stations. The USGS is working on both aspects in concert with NSF/IRIS.
