The link below, to "earthquake country", may have an error in the lengths of the 1960 M9.5 Chile earthquake rupture, and the 1964 Alaska rupture. The link says they were 1000 and 600 miles respectively...I think theye were 1000 km and 600 km respectively....the page below also says 600 miles for Chile. Kind of lame that a page talking about errors makes these kinds of errors...
