Geophysical processes and biosphere: article

Аnnotation: The article contains an overview of methods and algorithms for detecting seismic and infrasonic events, locating their sources, and recognizing their types. Algorithms and methods used in processing records of both standalone seismic stations and seismic and infrasonic arrays as well as net-works of stations are considered. Particular attention is paid to the application of the considered algorithms in modern automated seismic and infrasound monitoring data processing systems. The general task of seismic and infrasonic monitoring data processing is divided into five main subtasks: detection of useful signals on the record - seismic or infrasonic waves, determination of their parameters, their identification (determination of wave types); search for data fragments containing rec-ords of seismic or infrasonic events that must be processed by the system; association of detected events according to previously defined parameters for a network of stations; location of the source (epicenter/hypocenter) of seismic or infrasonic events; source type recognition. Each subtask and existing methods for its solution are considered separately. The issues of the sequence of solving the above problems and the possibility of combining them depending on the specific implementation of the processing system and the specific goals of data analysis are discussed. The article considers more than 100 papers describing both modern, high-performance algorithms and classical, but still relevant methods for processing seismic and infrasonic data, including algorithms previously proposed by the authors.
