This dataset is created to solve the problem of locating seismic signal sources. Synthetic waveforms were generated using Pyrocko, an open source seismological modeling framework [Heimann et al., 2018]. The propagation of seismic waves was modeled for an elastic-viscous layered medium. The velocity model of the medium was taken from [Málek, Horálek, Janský, 2005]. The sources of seismic signals were modeled by a double couple of forces with a random distribution of displacement directions (strike, deep, rake) and magnitudes uniformly distributed within the given boundaries (0–2). The epicenters and depths of the sources were set randomly within a region with a radius of 1.5 km and a depth of 1000 meters. Waveforms (displacement) were obtained for five stations (four symmetrically located at a distance of 500 meters from the origin, and one in the center) for three channels (two horizontal N, E and vertical Z) with a sampling rate of 100 Hz, the length of each record is 4 seconds. For each waveform, a priori times of arrival of the p and s phases were obtained. As a result of the simulation, training and test samples were formed from 10**6 and 10**3 events, respectively (15 waveforms in each).
