水化学地震前兆短临预报指标和方法研究

本文主要包括两方面内容：１．单项异常的判别和确认：２、短临预报指标的提取和地震三要素的预测。根据苏，浙，沪，皖水化测报区多年的预报实践和震例资料，从多种角度进行统计分析，结合日常预报经验，初步建立了反映现阶段资料状况和认识水平的统计性短临预报指标和地震三要素的预报方法。经检验，具有实用性和可操性作。

RESEARCH OF THE IMMINENT AND SHORT-TERM EARTHQUAKE PREDICTION INDEX OF HYDRO-GEOCHEMICAL PRECURSORS AND ITS METHOD

There are two subjects discussed in this paper :1. determination and confirmation of monomial anomaly;2. abstraction of the imminent and short - term prediction index and forecast of three elements of an earthquake. On the basis of the prediction practice for many years and a large number of earthquake case in Jiangsu, Zhejiang, Anhui provinces and Shanghai municipality, and combined with the routine prediction experiences, the statistical imminent and short -term prediction index and the prediction method for three elements of an earthquake, which reflect the datum quality and the knowledge level at present stage, have been roughly established. Through examination, the above-described method is practical and operatable.
