Appendix for the paper The Number 56 & Earthquake Cycles

Earthquake activity in Canada is mainly limited to the western and south eastern portions of the country. Eastern Canada has recorded events from the mid 17th century (Geological Survey of Canada). Strangely, all 9 major eastern quakes (mag => 6.0) occurred in the 4.5 months October 15 to February 28. Six of these quakes happened within the 9/56 year pattern presented subsequently, a figure that compared with an expected frequency of a mere 0.5.

Years in bold contain eastern Canadian major earthquakes in the 4.5 months commencing October 15 of those years in the table.

In western Canada, 11 major quakes (mag => 6.9) have been recorded since 1700, of which 5 happened in the 9.5 months commencing May 15 of those years in the ensuing 9/56 year pattern. Only 1.2 could have been expected by chance.

* Years in bold experienced major quakes in western Canada in the 9.5 months beginning May 15.

Combining these two lists from the Geological Survey of Canada gave a total of 20 quakes, of which 10 fell in the 9.5 months commencing May 15 of years in Table C. About 4.0 could have been expected by coincidence. Curiously, the quakes in eastern Canada tended to fall in the left hand side of the 9/56 year grid in Table C, while those in the western provinces took place in the right hand portion of these cycles.
