摘要

研究了瓦赫什河中上游HPP梯级区域的地震尾波衰减特征。分析了1958—1989年选频地震台站记录的局地地震短周期尾波，以及1989—2021年局地地震数字记录资料。对模拟地震台站和数字地震台站获得的地震资料进行了对比分析。考虑了地震波衰减场的空间不均匀性与HPP级联区域及其附近地区的构造和地震活动性的相关性。

The Seismic Quality Factor of the Lithosphere and Seismicity in the Area of the HPP Cascade of the Upper and Middle Reaches of the Vakhsh River

The seismic coda wave attenuation characteristic in the area of the HPP cascade in the upper and middle reaches of the Vakhsh River was studied. The short-period coda waves of the local earthquakes, as recorded by frequency-selective seismic stations in 1958–1989, and digital seismogram data earthquakes that occurred in region since 1989 until 2021 were analyzed. A comparative analysis of seismological data obtained by analog and digital seismic stations has been carried out. The correlation of spatial inhomogeneities of the S-wave attenuation field with tectonics and seismicity in the area of the HPP cascade and in nearby territories is considered.

期刊介绍： Seismic Instruments is a journal devoted to the description of geophysical instruments used in seismic research. In addition to covering the actual instruments for registering seismic waves, substantial room is devoted to solving instrumental-methodological problems of geophysical monitoring, applying various methods that are used to search for earthquake precursors, to studying earthquake nucleation processes and to monitoring natural and technogenous processes. The description of the construction, working elements, and technical characteristics of the instruments, as well as some results of implementation of the instruments and interpretation of the results are given. Attention is paid to seismic monitoring data and earthquake catalog quality Analysis.
