title: Commentary on “Earthquake Depths in the Crimea–Black Sea Region” by V.E. Kulchitsky, B.G. Pustovitenko and V.A. Svidlova
abstract: It is well known that the results of determining earthquake parameters depend to a large extent on data processing algorithms and velocity models of the seismic wave propagation medium used in solving hypocenter problems. In 1992, V.Yu. Burmin developed a hypocentric algorithm that minimizes the functional of distances between the points corresponding to the theoretical and observed travel times of seismic waves from an earthquake source to recording stations. The determination of the coordinate
