Abstract

For geodynamically active regions of the Earth, the task of geophysical monitoring is very urgent; geodynamic processes act on geophysical properties and fields. A successful solution to the problem of separating a magnetotelluric field into endogenic and exogenic components allows detection of the moment of fissure initiation, but so far without localization of the active area. For such localization (as a first approximation, direction finding), it is possible to monitor the seismoacoustic field, which is also associated with fissuring. The article describes the development and testing of a three-axis gradient system for recording the seismoacoustic field. Its technical support and requirements are considered in detail. The article presents the results of testing the system at fixed stationary points of the Scientific Station of the Russian Academy of Sciences in Bishkek. Such a gradient system gives grounds to separate sources by the direction to them owing to the presence of a vertical and two transverse components.

地球动力学活动区地震声波数据采集三轴梯度系统的开发

摘要

对于地球上地球动力学活跃的地区，地球物理监测的任务非常紧迫。地球动力学过程作用于地球物理属性和场。对于将大地电磁场分为内生和外生成分的问题的成功解决方案，可以检测到裂缝产生的时刻，但是到目前为止，还没有活动区域的定位。对于这样的定位（作为第一近似，方向寻找），可以监测与裂隙有关的地震声场。本文介绍了用于记录地震声场的三轴梯度系统的开发和测试。详细考虑了其技术支持和要求。本文介绍了在比什凯克（Bishkek）俄罗斯科学院科学工作站固定固定点测试系统的结果。由于存在垂直分量和两个横向分量，这种梯度系统使地面按源的方向分开。
