/* Major earthquakes are doubling every 40 years? */
::: The table in the cited reference shows an increase factor of 1.5-4 every 38 years, and recent trends confirm a substantial increase over the past few decades. The statement seems well-supported by the table and recent data.--[[User:Aschlafly|Andy Schlafly]] 19:56, 23 October 2011 (EDT)
::::Yes, but the cited reference contradicts its own cited reference, which is the USGS earthquake data (found in the NOAA database.) There has been a substantial increase per decade since 1980, a MINOR increase per decade since 1970 and no increase whatsoever since 1900. Anyone can cherry-pick figures to prove anything, but the long-term increase simply isn't there. There were more severe earthquakes between 1900 and 1910 than between 2000 and 2010. --[[User:MandyC|MandyC]] 20:13, 23 October 2011 (EDT)
