Abstract

Abstract—In my comment on the paper by A.A. Lyubushin, G.N. Kopylova, and Yu.K. Serafimova, I focus on the problem of legitimacy of seismological data pertaining to the unconventionally low frequency range from the standpoint of metrology and question the validity of the obtained results. The latter aspect is associated with the fact that in the discussed paper of Lyubushin et al. (2021), the estimates of confidence intervals in the calculated statistics are completely absent, which is at odds with the generally accepted approaches to the presentation of the results of measurement data processing. Without conducting such estimates, the authors made an unjustified conclusion about the correlation of the studied processes and, as a consequence, about a triggering effect of the irregularity of the Earth’s rotation on the seismic process.
