本文对松潘7.2级地震前后四川省水氡点的测值进行了较系统的分析研究,发现震前距该地震震中110公里范围以内的松潘川主寺和茂汶吉鱼寨两泉点的测值具有短期和临震异常,距该地震震中300公里以外的姑咱泉点测值具有区域性的临震突跳异常,康定泉点的测值具有区域性异常变化,并提出了松潘7.2级地震的水氡异常模型。文中还对上述四个泉点的地质构造背景和水文地质条件也作了简要介绍。
This paper makes a systematic analysis on the measured value of water radon point in Sichuan Province before and after the M7.2 Songpan earthquake and finds that before the earthquake epicenter within 110 km of Songpan Chuanzhusi and Maowenji Yuzhai springs With short-term and imminent anomalous earthquakes, with a regional sudden anomaly of sudden anomaly measured from the point Guquan that measured 300 km away from the epicenter of the epicenter. The measured value of Kangdingquan has regional anomalous changes and a rating of 7.2 Earthquake radon anomaly model. The article also made a brief introduction to the geological structure background and hydrogeological conditions of the above four springs.
