The new issue of The Russian Journal of Seismology - Vol. 4, No. 3, dedicated to equipment for seismological observations has been published. A large number of articles were submitted to this issue by researchers from different countries. In addition to Russia, scientists from Azerbaijan, Kazakhstan, Kyrgyzstan, and Uzbekistan presented an analysis of topical seismological problems. Unfortunately, it was not possible to publish all submitted articles in the current issue, but the publication will continue in the following issues.

The issue opens with an article traditionally published at the beginning of each semester by a team of authors headed by Yu.A. Vinogradov (co-authors: M.I. Ryzhikova, N.V. Petrova, S.G. Poigina, M.V. Kolomiets) with an overview of strong earthquakes on the Earth in the previous half of 2022 according to Earthquake Alert Service of the FRC CS RAS.

The second article, prepared at the Republican Seismological Service Center of the National Academy of Sciences of Azerbaijan under the leadership of ANAS Corresponding Member G.J. Etirmishli (co-authors: S.E. Kazymova, S.S. Ismailova, R.D. Kerimova). This work touches upon the key aspects of the history of the modernization of the seismological observation system in Azerbaijan and its current state.

Our colleagues from the Institute of Physics of the Earth of the Russian Academy of Sciences (A.B. Manukin, I.I. Kalinnikov, O.S. Kazantseva, V.P. Matyunin) demonstrated the main problems of seismic measurements not only on the Earth, but also on other planets of the Solar systems. Moreover, in their study, the authors focused on the parameters and principles of measurement using an accelerometer.

Representative of the Kamchatka branch of the FRC CS RAS Yu.V. Shevchenko shared his experience in operating the network of seismic stations in Kamchatka in the process of performing not only seismic monitoring tasks, but also tsunami and volcanic warnings. In addition, the article describes the technical aspects of the use of the SM-3 seismometer at radiotelemetric seismic stations.

In the fifth article, a large team of authors from the Institute of Seismology of the Academy of Sciences of the Republic of Uzbekistan under the leadership of L.A. Khamidov (co-authors: F.R. Artikov, Kh.L. Khamidov, B.R. Ganieva, S.G. Anvarova, F.I. Ibrogimov) provided an overview of the current state of instrumental seismic observations on reservoirs in seismically active regions of Uzbekistan. A historical overview of the development of the network is also given and the main guidelines for its further improvement are formulated.

The Novosibirsk Seismological Branch of FRC CS RAS took part in filling the issue with an article on the use of Baikal-8 recorders for seismic monitoring of buildings and structures in real time (authors A.A. Bryksin, P.V. Gromyko, D.B. Sevostyanov) . The paper gives examples of the operation of the software and hardware complex used in the branch at industrial facilities and in civil engineering.

Colleagues from Yuzhno-Sakhalinsk D.V. Kostylev, and N.V. Boginskaya, who work at the Institute of Marine Geology and Geophysics, Far Eastern Branch of the Russian Academy of Sciences and the Sakhalin branch of the FRC CS RAS, demonstrated their experience in installing and operating a molecular electron seismometer in the climatic conditions of Sakhalin Island. It is shown that climatic changes that occur from time to time and are expressed in the paucity of snow cover, which is usually abundant on the island, require a special approach to the operation of this type of equipment.

The issue ends with a congratulatory article by the editors of the Russian Seismological Journal on the occasion of the 90th anniversary of RAS Academician Vitaly Vasilyevich Adushkin.
