Abstract

This paper is concerned with the main stages in the setting-up and technical development of a system specializing in physical and chemical parameters of groundwater at a network of wells and springs in the Petropavlovsk Geodynamic Test Area, Kamchatka. The focus is on a description of hydrogeochemical and hydrogeodynamic precursors to Kamchatka earthquakes (М_w = 6.6–7.8) that occur a few weeks to a few months before a seismic event, manifesting themselves in anomalous changes in chemical composition and groundwater level. The precursors are discussed in application to their use at specialized councils on earthquake prediction. It is shown that the system of automated observation of groundwater parameters at wells as developed at the Kamchatka Branch of the Geophysical Survey of the Russian Academy of Sciences (KB GS RAS) is capable of identifying hydrogeodynamic precursors of water level in near real time and of providing, in some particular cases, quantitative estimates of pre-seismic and coseismic of deformation in water-saturated rocks. This can be useful in geophysical monitoring and intermediate-term prediction of strong earthquakes for the Kamchatka region.

堪察加水文地震学研究：1977–2017年

摘要

本文涉及在堪察加彼得罗巴甫洛夫斯克地球动力试验区的一个井和泉水网络中专门研究地下水的物理和化学参数的系统的建立和技术开发的主要阶段。重点是水文和hydrogeodynamic前体堪察加地震的描述（М_瓦特= 6.6–7.8）发生在地震事件发生前的几周到几个月，表现为化学成分和地下水位异常变化。在专门的地震预报委员会上讨论了这些前体的应用。结果表明，俄罗斯科学院地球物理调查堪察加分公司（KB GS RAS）开发的井眼地下水参数自动观测系统能够近乎实时地识别水位的水文动力前兆。在某些特定情况下，可以提供对水饱和岩石变形前震和同震变形的定量估计。这可用于堪察加地区的地球物理监测和强震的中期预测。
