I can't even process what a 9.7 would be like, let alone in a major city like Tokyo.
How many times more powerful than this last 9.0 is that?
Also, can you depend on the 'scales' that are popularly posted on USGS etc, or are they watered down and manipulated by, say nuke plant investment agents and enthusiasts. I would never have thought of that, had I not heard that many other scales, such as the air visibility index and the UV index have been updated recently to downplay certain 'new normals'. With so much of the US Gov info now coming from private companies, it's hard to believe anything without first doing complete research. For instance, the weather that you think the weather bureau gives out, is allegedly Raytheon Company, now.
Another thought, though associated with with this particular event/s in Japan this week. It's become extremely obvious that you should not, get your information from the companies that run systems in crises (these days that's just about everything), governments, or the corporate news (I say that word "news" so lightly).
