Abstract
A retrospective description of the evolution of the methodological approach to the localization of crustal earthquakes (conventionally called "refined hypocentry") is given using the example of data obtained in the Central Baikal region. Both archival records of past earthquakes (for the period 2001–2003) and relatively modern data (2020–2021) were used. A number of well-founded methodological solutions are proposed to improve the accuracy and reliability of localization with examples of their application on real data.
Supporting agencies: the study was carried out within the framework of the project No. FWZZ-2026-0050. The author is grateful to the staff of the Buryat Branch of the Geophysical Survey of the Russian Academy of Sciences, and Geological Institute SB RAS (Ulan-Ude) for providing source data.
