| 内容記述 | Many Japanese research and administrative institutions, including universities, the National Research Institute for Earth Science and Disaster Resilience (NIED), and the Japan Meteorological Agency (JMA), collect and catalog seismic observations. Although each institution independently collects these data, practically all seismic data are distributed among Japanese research institutions and the JMA through a data exchange network in real-time using the WIN system. The Earthquake Research Institute (ERI) of the University of Tokyo has collected waveform data since September 19, 1989. ERI stores seismic data with a volume of about 320 TB. Continuous waveform data are increasing every minute by about 60 MB. Recent progress in information technology makes it possible to have all long-term continuous waveform data online for various analyses. However, it is still difficult for individual institutions to use all available data because of the high costs of implementing and maintaining both a large data storage server and a data-analyzing server for such a large volume of data. Therefore, the most efficient solution is to establish a nationwide shared storage and analysis system that is large enough to store all available data online for a continuous data analysis system, which is open to all research institutions. We have developed and installed a petabyte-scale seismic data analyzing system at ERI to create a Joint Usage/Research Center. This system mainly consists of four Linux computers and one storage system with a capacity of 1 PB. This system provides researchers with tools and data, and produces leading-edge scientific results. | |||||
