Rescuers received information about the incident on the evening of 17 August. According to preliminary information, at an altitude of 41, -4.2 km, two tourists stumbled, descending from the glacier and fell off the slope. Since it was already dark at that time, the rescuers could not use the helicopter for searches. The Mi-8 flew to the site on the morning of 18 August.
The rescuers disembarked at an altitude of 1.1 km, where employees of the Klyuchevsky branch of the PSO have already arrived. By evening, a group of rescuers climbed to an altitude of 2.5 km and camped there for the night to avoid altitude sickness. On August 19, rescuers continued their ascent to Klyuchevskaya. According to the Investigative Committee for the region, the bodies of the victims were found by a member of the group. The tourist group that climbed Klyuchevskaya included 12 people from Moscow, Zheleznogorsk, St. Petersburg and Kaliningrad.
Earlier it was reported that while climbing the volcano, 35-year-old Alexander Filyaev and 46-year-old Andrey Zakalin (deputy of the city council of Zheleznogorsk) were killed.
