The next issue of The Russian Journal of Seismology (Vol. 6, No. 1) has been published. The issue contains publications by researchers covering a wide range of regions of Russia, as well as from several other countries.

The issue opens with a traditional semi-annual article “Global earthquakes in the 2023 second half according to the GS RAS” (authors: Yu.A. Vinogradov, M.I. Ryzhikova, N.V. Petrova, S.G. Poygina, M.V. Kolomiets), which provides information on the seismicity of the Earth in the second half of 2023, as well as on earthquakes felt in the Russian Federation according to GS RAS data. It is noted that the seismic energy released on the globe in the second half of 2023 decreased compared to that in the first half of the year and remained below the six-month average for the period 2010–2023.

Next are our colleagues from the IS NAS KR, Bishkek, Kyrgyz Republic K. Omurbekkyzy, M. Omuraliev, A. Omuralieva, K.E. Abdrakhmatov was presented in their article “Study of daily industrial explosions at the Kumtor deposit, Kyrgyzstan, in 2020-2021” results of determining the velocities of seismic waves of industrial explosions in the Central Piti n 2020–2021. according to data from “Taragai” digital stations. It is noted that daily industrial explosions affect the environment and geodynamics of the Tien Shan lithosphere through the accumulation and injection of seismic energy and vibration. The probabilities of the occurrence of fluids, partial melting and high pressures in the studied area of the Tien Shan mountain building region are shown.

The team of authors of the article “Strong earthquake on January 22, 2024 with Mw=7.0 in the south of the Tien Shan” from the GS RAS, Obninsk, Russia; IS NAS KR, Bishkek, Kyrgyzstan; IGR NNC RK, Kurchatov, Kazakhstan (I.N. Sokolova, I.P. Gabsatarova, A.V. Beryozina, I.L. Aristova) presented the first results of the analysis of instrumental and macroseismic data from the strong earthquake of January 22, 2024 in the area of the Gissar-Kokshaal fault of the Tien Shan. The obtained solutions for the mechanisms of the main shock sources and the strongest aftershocks showed the predominance of reverse-thrust type mechanisms; the strike of nodal planes along the fault was established, which is consistent with the northeastern orientation of the cloud of aftershocks and, in general, with the geodynamic situation of the junction zone of the Tien Shan and the Tarim Basin. The dependence of the intensity in points on the distance for this earthquake was plotted.

Regular authors of the Russian Journal of Seismolog from the Republic of Armenia: R.A. Pashayan, J.K. Karapetyan, L.V. Harutyunyan, S.S. Margaryan, A.A. Gevorgyan, R.A. Karamyan, K.G. Tovmasyan (IGES NAS RA, Yerevan; IGES NAS RA, Gyumri; IGIC NAS RA, Yerevan; RSSP MES RA, Yerevan) presented their new article “Seismotectonic activity of earthquake source zones in Northern and Central Armenia for the period 2019–2023”, in which they analyzed the seismic regime and constructed earthquake recurrence graph. The geodynamic activity of focal and fault zones was studied using hydrogeological methods for studying the geodynamic processes of the earth's crust and identifying hydrogeodynamic and hydrogeochemical effects that precede tectonic movements of the earth's crust.

Representative of the GS RAS from Perm A.S. Zvereva in her article “Coda Q lapse time dependence in the lithosphere of the North Caucasus” investigated the correspondence of the results of the calculated values of the quality factor using the coda-wave envelope method for the North Caucasus region and the theoretical model of changes in the quality factor in a vertically varying model of the turbidity of the environment, proposed by A. A. Gusev in 1995.
