I was driving home from work. Merely a chance to see it. Earth quake 5 days later usgs "surface". What are the chancing of it being a timedelay Nuclear bomb droped on Saturday at night no one saw it on Thursday. 120 hours later Thursday. Under ocean. No flash. No splash. It detonated. Remember Fukashima? I walked outside at 3am looked up saw "something" enter the atmosphere white ion trail over head and object Disappeared off horizon. Fukushima earth quake followed later. (Could it have been time delay detonation under water deep below off the coast of Japan)
