Reply to the comment by Alexander G. Sorokin, Anatoly V. Klyuchevskii on “Hovsgol earthquake 5 December 2014, MW = 4.9: seismic and acoustic effects” by Anna A. Dobrynina, Vladimir A. Sankov, Larisa R. Tcydypova, Victor I. German, Vladimir V. Chechelnitsky, Ulzibat Munkhuu
Tóm tắt
We again give thanks to A. Sorokin and A. Klyuchevskii and the Editorial Board of the Journal for the opportunity to discuss our results that have been published in the “Journal of Seismology” (Dobrynina, A.A., Sankov, V.A., Tcydypova, L.R., German, V.I., Chechelnitsky V.V., Ulzibat M. Hovsgol Earthquake 5 December 2014, Mw = 4.9: seismic and acoustic effects // J Seismology. 2018. V. 22, Is. 2. P. 377–389.

). In our article, on the basis of the arrival time of the infrasound signal at the Tory site, the seismic waveform analysis and evaluations of the horizontal and vertical surface displacement, we suggested that the registered acoustic signal of the Hovsgol earthquake on 5 December 2014, Mw = 4.9 was generated by the interaction of seismic waves with the regional topography. In contrast, A. Sorokin and A. Klyuchevskii believe that the infrasound signal was associated with flexural waves from ice on the surface of the lake above the source of the earthquake. However, there are many crucial points in their comments that we find to be scientifically flawed and poorly reasoned. In this reply, we give a detailed response to their comments.
