On April 15, BORIS GRIGORYEVICH BUKCHIN died in the Holy Land after a severe long illness.

B.G. Bukchin was born on March 6, 1947. In 1972 he graduated from the Moscow Institute of Physics and Technology, in 1980 he defended his dissertation for the degree of Candidate of Physical and Mathematical Sciences. In 1972 – 1975 he worked in the Computer center of the Ministry of Geology of the Russian Federation. Since 1975 he worked at the Institute of Physics of the Earth of the USSR Academy of Sciences in the Department of Computational Geophysics, which was reorganized in 1990 into the International Institute of Earthquake Prediction Theory and Mathematical Geophysics of the USSR Academy of Sciences, currently the Federal State Budgetary Institution of Science Institute of Earthquake Prediction Theory and Mathematical Geophysics of the Russian Academy of Sciences (IEPT RAS). From 1993 to 2012 he worked as a visiting researcher and visiting professor at Institut de Physique du Globe de Paris (IPGP).

Boris Grigoryevich was a well-known specialist in the field of studying and modeling the process of seismic wave propagation in complex media, he developed methods for determining the integral parameters characterizing the focal mechanism, seismic moment, earthquake focus depth, its geometry, duration and process of discontinuity propagation based on the analysis of seismic wave spectra.

Boris Grigoryevich was well known far beyond the borders of our Institute. He was the organizer and, at the same time, an active participant in six international schools on modeling seismic waves and their inversion at the Abdus Salam International Center for Theoretical Physics of UNESCO-IAEA, has always been a welcome guest at conferences and schools for young scientists of the Geophysical Service of the Russian Academy of Sciences.

Boris Grigoryevich was a generous, kind, sensitive and sympathetic person. He enjoyed great prestige among colleagues, was an example for all. His life optimism, excellent sense of humour, goodwill, ease of communication created a special atmosphere around him; it was easy and pleasant to work with him.
