发展、完善地震数据计算机实时处理系统是实现地震预报特别是短期预报的基本条件之一。日本在建立东海和关东地震观测台网的基础上研究开发了计算机地震数据处理系统。本文概述了日本国立防灾科学技术中心的计算机地震前兆数据分析处理系统,包括系统概要、硬件部分、地震前兆分析处理流程等方面。 Development and improvement of seismic data computer real-time processing system is one of the basic conditions to realize earthquake prediction, especially short-term forecasting. Based on the establishment of the East China Sea and the Kanto Earthquake Observatory Network, Japan has developed a computerized seismic data processing system. This article provides an overview of the computerized earthquake precursor data analysis and processing system at Japan’s National Center for Disaster Prevention Science and Technology, including system overview, hardware components, and earthquake precursor analysis and processing.
