The video shows a time lapse of these events. Except for the two Japanese cities, those were all nuclear tests conducted as part of developing nuclear weapons, the majority of them under ground.
You can see months and years passing by and each country is assigned a different tone. The video ends in 1998 but we all know that since then North Korea did some tests as well.
A pure horror to watch. I never knew British used Australia for this messy business...
