7.0’s are not all that exceptional (unless you’re IN ONE!), there are probably hundreds of those around the globe per year. But this is ring-of-fire territory, and given what happened in Japan, it’s probably newsworthy...
And it burns, burns, burns....
Not hundreds above 7.0, more like 15. Hundreds above 6, thousands above 5.
