The study analyzes the effects of an underwater explosion recorded in the Baltic Sea on September 26, 2022, with coordinates: 54.675 North and 15.574 East at a depth of 76.2 m. Based on data from the seismic monitoring system, the detonated charges were estimated at 750 kg of TNT. Then, the empirical equations of R. H. Cole and Warren D. Reid were used to calculate water pressure distribution and determine the danger zones for marine technology, ships, people, and sea fauna. The results are presented in graphical and tabular form. Based on the calculations, the explosion impact area was determined at over 6,700 m from the epicenter.
