Biography A Gusev

After graduating from Lomonosov, he came to Kamchatka, with which all his further professional activity is associated. The scientific career of A. in the city of this laboratory already as the “Laboratory of Seismology” in Gusev conducted research in the following main directions: the focus of the earthquake and its tectonophysical nature; fractal properties of seismic and volcanic processes, signals and fields; engineering seismology; absorption and scattering of seismic waves; Search for harbingers of earthquakes.

In each of these directions, he received fundamental scientific results, widely known and recognized both in our country and abroad. A brief chronology of its most important scientific results is as follows. In gg. Gusev first applied the principles of recognition of images to the forecast of earthquakes in time. He developed an algorithm for the forecast using several parameters of the earthquake catalog.

In the period gg. Alexander Alexandrovich developed algorithms, methodology and program for calculating the hypocrosters for the regional seismic network, which was the basis of his candidate dissertation on the topic “Determining the hypocrosters of close earthquakes for computer on the example of Kamchatka”, successfully protected in the city Gusev also assessed the seismic danger to the site planned in Kamchatka NPP.

Alexander Alexandrovich developed a method for the prediction of strong seismic soil movements based on the extrapolation of focal spectra along the scale of the moment magnituds, for which he built a fundamentally new scheme for the scale of focal spectra with a violation of the likeness of bicom -humped spectra and gave a tectonophysical explanation of this scheme.

Gusev proposed a description of the focus of the earthquake at high frequencies as an extended non -agent emitter distributed along the focus, and built on this basis the theoretically sound patterns of damping amplitudes near the extended hearth. This made it possible to determine the scattering parameters in the lithosphere of Kamchatka, to confirm and clarify the degree nature of the range of heterogeneous lithosphere.

Alexander Alexandrovich proposed the first realistic assessments of the parameters of dangerous soil movements for Petropavlovsk-Kamchatsky. Gusev created an algorithm and programs for calculating seismic danger used in the preparation of seismic regions of the Koryaksky AO, and then Russia. Gusev, as part of the team of OSR developers in Gusev, developed a unique methodology for restoring the vertical profile of the clushing coefficient of turbidity for longitudinal and transverse waves in the lithosphere according to the vulgarization of a non -power pulse with a distance.

The vertical thorough profile for the upper km of the medium under Kamchatka has been reconstructed. Alexander Alexandrovich revealed the phenomenon of the episodic of grouping in the sequence of eruptions of volcanoes and at the pace of removal of volcanism products, first for the explosive volcanism of Kamchatka, and then for the Earth as a whole. Gusev synthesized, with the aim of using high -altitude buildings in the design of high -rise buildings, soil movement options in Moscow, excited by a strong possible earthquake from the Romania Vranch zone, for which he developed special algorithms and methods.

Gusev developed fundamental approaches to the automation of the seismological subsystem of the warning system about the tsunami in the Far East of the Russian Federation and offered effective algorithms for the rapid localization of the possible source of the tsunami and the assessment of its tsunamigous potential. Alexander Aleksandrovich Gusev was an outstanding specialist in the field of seismology, and in particular in its directions as: the physics of the focus of the earthquake, the harbingers of earthquakes, the destructive fluctuations of the soil, scattered seismic waves, processing data and solving reverse tasks.

He made a very great contribution to the improvement of regulatory documents on seismic -resistant construction in Russia and ensuring the safety of the population of seismically active territories. With all his activities, Alexander Alexandrovich earned the deep respect of the leading seismologists in the world. His works are widely known to specialists and received worldwide recognition.

Numerous methods and computer programs created by him are used in the current processing of data obtained by the Kamchatka branch of the Federal Research Center “Unified Geophysical Service of the Russian Academy of Sciences” of the Russian Academy of Sciences. Alexander Aleksandrovich regularly participated in Russian and international conferences as an invited speaker and convention.

His public performances have always been carefully thought out and aroused invariable interest. A. Gusev devoted a lot of effort and time to the upbringing of youth. He gave lectures, generously shared his knowledge, experience and ideas, the stock of which never exhausted. He prepared five candidates of sciences. The bright memory of Alexander Alexandrovich will forever remain in the hearts of those who were lucky to cooperate, communicate and make friends with him.
