摘　　要：数字地震观测报告是计算视应力等重要参数的基础性资料。JOPENS数据服务可提供地震目录,为使用ESSA软件计算视应力等参数提供了前提,但ESSA与JOPENS数据服务没有程序接口,需要从JOPENS数据服务网站手工下载地震目录并按需求人工筛选数据编制成数字地震观测报告。针对手工编制数字地震观测报告效率低且容易出错的问题,利用MATLAB开发出一套程序,对数字地震观测报告的编制实现了自动化处理,大大提高了工作效率,降低了出错率,能够更好地为地震分析预报工作提供数据服务。Digital seismic observation report is the base for calculating some important parameters such as apparent stress and etc..JOPENS data services can provide earthquake catalogue,which is the premise of apparent stress parameter calculation by using ESSA software.However,since the ESSA and JOPENS data service has no program interface,there is a need from the JOPENS data service manually download earthquake catalogue and demand of artificial screening data into digital seismic observation report.In order to solve this problem,we utilize MATLAB to develop a set of procedures,compilation of digital seismic observation report with automatic processing procedure,which greatly improve the work efficiency,reduce the error rate,provide the better data service for earthquake prediction.
