Comparison of estimates parameters of earthquakes in the Kamchatka region from different catalogs

he article presents the results of work with such devices as the digital engineering seismic station «TELSS — 3» (LLC «Geosignal»), complete with seismic streamer SM — 20 and seismic receivers GS — 20 DX in order to clarify soil conditions in the valley of the Avacha river in Yelizovsky urban district. The method of refracted waves of seismic exploration was performed for the first time. It is important to note the importance of the seismic station for obtaining primary acoustic data for further refinement of seismic increments. Thanks to the data obtained, it becomes possible to make the right decisions when designing construction objects.
