At 08.40 (Moscow time) on January 28, a crack up to 7 meters wide was formed in the ice off the coast in The Mordvinov Bay, the Sakhalin region, 2 km from the shore. 635 amateur fishermen were cut off from the coast.
At 14.40 (Moscow time), all people who needed to be evacuated were brought ashore by rescuers. None of those rescued needed medical assistance. The rescue operation involved 20 people, 16 units of equipment, including 15 people from the Ministry of Emergencies and 10 units of equipment, including 3 boats and 1 hovercraft "Khivus-10".
Contrary to common sense and rescuers' warnings, who were informed via SMS messages and the media that going out on the ice is extremely dangerous, several hundred people decided to try their luck and went out on unreliable ice.
