APPENDIX 24              USGS MAJOR WORLD EARTHQUAKES: 1700-2004

HOME

Appendix for the paper The 9/56 Cycle & Earthquake/Volcanic Cycles

The United States Geological Survey  presented a listing of 45 biggest recorded earthquakes (mag =>8.0) occurring around the world between 1700 to 2006. Of this total figure, 15 happened in the 12 months ended June 15 of those years in the 9/56 patterns in Table A this appendix (significant p < .001). This effect applied to the biggest recorded earthquakes. Of the 22 biggest world quakes (mag =>8.3), 11 appeared in the 9/56 year grid in Table A, whereas 3.1 could have been expected by chance. Of the 23 events of magnitude between 8.0 & 8.3, only four appeared in Table A, a finding which could be expected by chance.

NB: Earthquakes presented in red occurred in the 12 months ended June 15 of those years in the 9/56 year grid in Table A.
