This is the moment a group of scientists got trapped near a volcano in Russia's far east after a rock fell causing huge ash clouds on April 11.

The group of six was at the Bezymianny volcano on the Kamchatka Peninsula as part of an expedition aimed at studying the volcano's activity, as well as taking aerial photographs.

This dramatic video, which was filmed by Petr Krinkin, shows the moment the enormous ash cloud begins to cover the sky. The team can be seen running to find shelter. Scientists take cover underneath special vehicles that look similar to snowmobiles.

Bezymianny had been actively erupting since the end of March, with lava flowing from its crater and ash clouds billowing into the air. The edges of the crater were prone to collapse. Despite these warning signs, the group departed from the Apakhonchich base station on April 7 to reach Ambon Rock, which was relatively close to the volcano. They planned to collect samples and install gas analyzers and mobile stations.

The scientists were not able to move from their location due to the heavy ash fall and the danger of new rockslides. They managed to establish communication with the rescue team. Rescuers only managed to reach them the day after due to harsh weather conditions.

The six scientists were safely evacuated and reported minor injuries.

Scientists trapped in Russia's Bezymianny volcano during rock collapse and gigantic ash clouds: On April 11th, 2023, a group of six scientists found themselves trapped in a powerful ash and rock fall while on an expedition to study the active volcano Bezimyanny on Kamchatka, Russia. The scientists had set out to conduct a survey of the volcano's activity and perform aerial photography. The video of this incident was filmed by Petr Krinkin.

Bezimyanny had been actively erupting since the end of March, with lava flowing from its crater and ash clouds billowing into the air. The edges of the crater were also prone to collapse. Despite these warning signs, the group of scientists departed from the Apakhonchich base station on April 7th to reach Ambon Rock, which was relatively close to the volcano. Their plan was to collect samples and install gas analyzers and mobile stations.

As the group approached the volcano, a sudden ash and rock fall occurred, trapping them in their location. The scientists were not able to move due to the heavy ash fall and the danger of further rockslides. They immediately contacted the authorities for help, but due to the remote location, rescue efforts were hindered.

The scientists were able to establish a communication line and update the rescue team on their situation. However, the rescue team was unable to reach them until the following day due to the harsh weather conditions and the difficult terrain. The scientists were equipped with survival gear and managed to keep themselves warm and sheltered through the night.

When the rescue team arrived, they were able to safely evacuate the scientists. Although the group had suffered minor injuries, they were all in stable condition and received medical attention.
