The Sakantsy forest lake in the Vladimir region suddenly disappeared overnight after being drained by a giant sinkhole.
The 20-meter-deep reservoir and all its fish were swallowed up within hours by a giant crater.
On October 12, the forest lake Sakantsy went underground, swallowed up by a giant sinkhole that formed overnight.
The giant crater also engulfed all of the fish, the algae and other animals present in the 20 meters deep lake.
According to experts, the sudden disappearance of the reservoir is related to geological processes in the area since the region is made up of karst, which easily dissolves and erodes, forming giant cavities and sinkholes like in Florida.
Another weird and impressive geological phenomenon occurring around the world.
