I rented the DVD for this movie because I remembered reading about it when I was a kid. With this film, the Soviet Union attempted to "cash in" on the success of western disaster films like "Earthquake" and "The Towering Inferno." I rented the movie because I thought it might be interesting from an historical standpoint.
The film was about 20 minutes longer than it needed to be, and it suffers from too much set-up -- nothing disasterous happens until over an hour into the picture. But the carnage does eventually start, and those scenes are pretty good, especially the ones set at the airport located in a canyon. The effects crew did a remarkable job with what appeared to be meager resources.
