数字波形地震预测辅助分析软件

Aiding Software for Seismic Forecast Analysis of Digital Waveform Data

自"九五"以来中国地震局在中国大陆不同地区建立了大量的数字化地震观测台站,为地震预测和数字地震学的研究工作提供了海量的可靠的数据资源。利用这些数字化波形数据目前已开展了大量的地震预测研究工作,取得一系列成果,为地震预测提供了新的思路和方法。为此,在地震预测和数字地震学相关研究工作中,数字波形分析方法及其相关处理软件对于地震波信息的挖掘变得越来越重要,基于此原因研制了《数字波形地震预测分析软件系统——wavePRED Version 2007》。通过一段时间的检验和应用,认为该软件可作为地震预测和数字地震学研究工作中一款分析工具。本文首先概述了利用数字波形进行地震预测工作的重要性及其存在的一些问题,然后介绍了wavePRED系统的研制意义、设计目标、研制思路、系统具有的一些特点、构建系统的框架体系、操作界面、技术特点、方法与功能等,给出了该系统的应用实例,最后对软件中存在的问题进行了讨论,也对软件的未来前途进行了美好展望。

Since the Ninth ＂Five-year Plan＂, China Earthquake Administration has established many digital seismic observation stations in different areas of the Chinese Mainland, which provided mega reliable data for earthquake forecasting and digital seismology. These digital wave data have been widely used in earthquake forecast with many achievements and provide new insights and approaches for earthquake forecast. Digital seismic wave analysis and its software are becoming more and more important in the study of earthquake forecasting and digital seismology. Software for Seismic Forecast Analysis of Digital Seismic Waveform Data——Wave PRED Version 2007 was developed for this purpose. The actual application proves that the software serves well as a tool in earthquake forecasting and seismology study. After discussing the importance of the use of digital waves in earthquake prediction and its problem, the paper explores the significance of the wave PRED＇s development, its designing objectives, system frame and technological features. The paper also discusses the problems in the software as well as its prospects.
