Identification of Linear Formations in the Structure of Seismicity by Calculating the Scalar Products of Pairs of Seismic Events That Are Closest in Time
A method is proposed for calculating scalar products of pairs of seismic events that are closest in time to isolate sequences of epicenters of crustal earthquakes (chains) connected in space and time. To verify the developed methodology, the model and real catalogs of earthquakes of the Garm region in Tajikistan are compared. The efficiency of the proposed algorithm is shown. Based on the totality of the results of the allocation of chains, the issues that complicate the detection of the mentioned structures in the general case are considered. In the process of applying the created program to the real catalog of earthquakes of the Garm region, the existence of four pairwise orthogonal prevailing directions in their orientation was established. There were also some changes in the time of the predominant role of the selected strike of chains of earthquake epicenters. It is possible that these changes may reflect some elements of the dynamics of the seismic process in the Garm region.
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.
