What were GLP'ers watching during the following threads?

Thread: Live Feed of Fukushima Geothermal Power Plant
Thread: Dense smoke at FUK #4 (Page 7)

I was watching the same thing; took pictures via their webcam and put together into a video. I watched 3 separate "explosions" occur during a 3 to 4 hour period. What are these explosions? Colored pink to purple. Some people believe it was snow but dense particles are coming at the camera. Eventually the camera melted away. Yes, the camera was at the Fukushima geothermal plant, not the nuclear power plant. The geothermal plant is some 60+/- miles away from the nuclear power plant. Either way, the web camera is in Fukushima, and I'd love to know what I and other GLP'ers were witnessing early that morning. Any ideas?
If someone could embed the video it'd be appreciated. Peace!
