Abstract

The results of study of the emanation response to large seismic events within the Baikal region for a year are study. In the course of this study, monitoring of the radioactivity of underground waters in the Southern Baikal region was organized and a set of the most significant earthquakes was identified. The radii of the influence zones of these seismic events were calculated, and these zones were grouped in accordance with their spatial position relative to the sampling station. Three types of emanation responses to seismic events have been identified, one of which reflects the emanation field response not to the event itself, but to the process of its preparation; i.e., it is a precursor effect. The grouping of seismic events in terms of their distance from the sampling station virtually coincides with how the events are grouped based on the type of emanation response. The results obtained show that the identification of short-term emanation precursors of strong earthquakes within the Baikal region is possible if a seismic event is strong enough and if a monitoring station is located within the zone of influence of the event.

贝加尔湖南部地区地下水氡活动的变化：地震的辐射响应

摘要

研究了贝加尔湖地区一年来对大型地震事件的辐射响应的研究结果。在这项研究过程中，组织了对贝加尔湖南部地区地下水放射性的监测，并确定了一组最重要的地震。计算这些地震事件影响带的半径，并根据它们相对于采样站的空间位置对这些带进行分组。已经确定了三种对地震事件的辐射响应，其中一种反映了辐射场响应不是对事件本身，而是对它的准备过程；即，它是一种先兆效应。根据距采样站的距离对地震事件进行分组实际上与基于辐射响应类型对事件进行分组的方式一致。获得的结果表明，如果地震事件足够强并且监测站位于事件影响区内，则可以识别贝加尔湖地区强地震的短期辐射前兆。
