The 30-day I1 declined below +6.5 today, which is why I chose to enter the ETF shorts. I will increase short ETFs until they are at least 10% capital.
There is a Wikipedia table listing history's greatest earthquakes going back to 869AD in Japan when records were kept. Since 2004 there have been 5 that have made the list, all >= 8.5 Richter. I realize that recordkeeping was sporadic and intensity only estimated in the pre-1900 quakes. However, this is an unmistakeable trend.
