Abstract
The Klyuchevskoy group of volcanoes is a unique research object, also from a seismological point of view. Classical high-frequency and long-period earthquakes of varying depths are being observed here, and the installation of temporary stations as part of the KISS project has made it possible to apply new methods to classify the observed seismicity. Two methods for determining seismic moments are used in the study. The spectral ratio method is used for the first time, which makes it possible to estimate the seismic moments of source spectra for the magnitude range Mw = 1–3. An independent assessment of seismic moments is also performed using a spectral method based on the level of low-frequency plateau of the amplitude displacement spectrum of body waves, and relation with the local magnitude is studied.
