The article is devoted to the problem of forecasting strong earthquakes by the geomagnetic method. The geomagnetic method is widely used on this problem in seismically active regions of the world as one of the promising, infor-mative and operational geophysical methods. The results of long-term geomagnetic studies on the problem of forecasting strong earthquakes in Uzbekistan are presented. Geomagnetic studies were carried out on the territories of the Tashkent, Ferghana, and Kyzylkum geodynamic polygons in the epicentral zones of strong earthquakes that occurred. Long-term, medium- and short-term precursors of earthquakes have been identified. Anomalous changes in the geomagnetic field associated with the decline in aftershock activity were also revealed. The dependence between the duration of the manifestation of long-term magnetic precursors and the magnitude of earthquakes is deter-mined. Absolute proton magnetometers MMP-1, MV-01 (Russia), and G-856 (USA) were used to measure the geomagnetic field.

The continuous aquifers of the Congolese Cuvette basin constitute the seat of significant water tables reversibly supplying the Congo River basin as well as the water tables they drain. Consisting mainly of sandy-clayey-sandstone formations, these aquifers contain groundwater which is the main source of drinking water supply for communities in this sector of the departments Cuvette and Cuvette-Ouest. The need for water being more and more acute, these aquifers have been subjected to drilling operations in order to supply drinking water to these populations. The information obtained from these operations is data which made it possible to obtain information relating to the lithology, the hydrogeological parameters of these aquifers and information on the depth and on the lateral variations of the water table. The purpose of this present work is to contribute to the hydrogeological characterization of the aquifer of the Cuvette basin in the departments of Cuvette and Cuvette-Ouest via data from the analysis of the technical sheets of drillings carried out by the ASPERBRAS Company, collected at the Ministry of Major Works and territory planning. This characterization was made using Visual MODFLOW Flex 2015.1 software coupled with Surfer 10 software and Rock Works 17 software. The hydrogeological interpretation of the
刚果Cuvette盆地的连续含水层构成了重要的地下水位的所在地,可逆地供应刚果河流域及其排水的地下水位。这些含水层主要由砂质-粘土-砂岩地层组成,含有地下水,是Cuvette省和Cuvette- west省这一地区社区饮用水供应的主要来源。由于对水的需求越来越迫切,为了向这些人口提供饮用水,这些含水层已经进行了钻探作业。从这些作业中获得的资料是能够获得有关这些含水层的岩性、水文地质参数以及关于地下水位深度和横向变化的资料的数据。目前这项工作的目的是通过对在主要工程和领土规划部收集的ASPERBRAS公司进行的钻探技术表的分析所得数据,对Cuvette和Cuvette- west省Cuvette盆地含水层的水文地质特征作出贡献。使用Visual MODFLOW Flex 2015.1软件结合Surfer 10软件和Rock Works 17软件进行表征。的水文地质解释
