RUSSIAN JOURNAL OF EARTH SCIENCES, VOL. 20, ES2001, doi:10.2205/2020ES000704, 2020 Figure 7. The spectral ratio by sectors for source spectra of earthquakes near the Aleutian fault (sectors 9–16) and the Bering fault (sectors 45–52). The scale for ordinates is arbitrary to focus on the shape differences of determined spectral ratio. The blue stripes indicate the presence of the first corners, green stripes - of second corners, grey one – of the third corners or "source-controlled $f_{max}$" which is present only for sector 9. The main reason for absence of $f_{max}$ is low SNR after 10 Hz for majority of records. Solid stripes are for clear evidences (as humps on the figures), while dashed stripes are cases that show insignificant humps for a sector Copyright 2020 by the Geophysical Center RAS.
