It takes but seconds for a small cloud of steam, appearing harmless at first, to erupt into a hot water geyser rivaling Old Faithful. What you don't see from the video are the brick-sized chunks of pavement and rocks that were launched into the air and onto the surrounding vehicles. Within minutes, a large flow of water has flooded the parking area as the natural geyser continues to spew water and steam hundreds of feet into the air.
If this happened in our backyard, we would hightail it out of town fearing another eruption of Vesuvian magnitude – yet the locals in Smolensk seem only slightly disrupted, continuing to seek open spots in the parking lot despite the odd chaos mere yards away.
With an impressive video
