Finnish media wrote that these events took place near Primorsk and Vyborg, in the territorial waters of the Russian Federation, about 40 kilometers southwest of the coast.
According to Finnish seismologists, four seismic events with magnitudes ranging from 1.3 to 1.8 occurred in the area of the Nord Stream gas pipeline in the Gulf of Finland, about 40 kilometers southwest of Vyborg. Later, another was recorded – a magnitude of 1.4. On Monday, October 24, Ilta-Sanomat edition reported.
It was determined that it happened on October 20 and 21. It was also reported that the explosions occurred from 12.35 to 18.32: at 12.35 a shock of magnitude 2.0 was recorded, at 14.02 – a magnitude of 1.5, at 17.54 – a magnitude of 1.5, at 18.32 – a magnitude. Another explosion was registered on Friday at approximately the same place at the same time interval.
According to the automated measurement system of the Institute of Seismology of the University of Helsinki, these are explosions or collapses.
“They were detected and identified. These are explosive signals. At least it’s not an earthquake,” said seismologist Jari Kortstrom.
He added that in the most innocent cases, explosions occur due to the deepening of the shipping channel. Another reason may be military exercises, when, for example, depth charges or mines are detonated.

Recall that on September 26, the Nord Stream and Nord Stream-2 were in full swing pressure drop in three lines of gas pipelines. Russia called the incident sabotage. Sweden announced the completion of an investigation conducted jointly with Denmark and Germany. The explosions were blamed on leaks..
