Abstract
- The paper presents a new approach to the description of earthquake seismic signals based on the nonorthogonal amplitude-frequency analysis of the smoothed signals (NAFASS) method. The authors consider an example of the processing of one of earthquake’s records that occurred in the Tien Shan territory. The earthquake signals were recorded at the Karagai-Bulak seismic station, which is a part of the digital telemetry network KNET, located in the Northern Tien Shan area. The paper presents the results from the first stage of creation of a collection of blow-like signals with beatings (such as earthquakes) «fingerprints», which will provide additional information characterizing the modern geodynamic processes of the Tien Shan. Such analysis of seismic signals for the Tien Shan earthquakes has not been carried out yet. The authors hope that using the reduced fractal model on the base of NAFASS method will help avoid extensive calculations of standard methods and directly construct a quantitative description of earthquakes in the terms of a common set of fitting parameters by creating a «waveform portrait» of a seismic event.
