Appendix for the paper 9/56 Year Cycles: Earthquakes & Volcanoes


Kostoglodov & Pacheco (1999) gave a listing of the major Mexican earthquakes (mag =>6.5) during the 20th century. Of the 182 quakes listed  - 66 occurred in the 12 months ending December 31 of those 9/56  years presented in Table A (significant p < .01). 

The researchers also presented a map of major earthquakes in southern Mexico. Of the 44 quakes noted on the map - 20 occurred in the year ended December 31 of those years Table B (significant p < .01).

The 56 year sequences are separate from each other by an interval of 9 years.
Years in bold contain major Mexican earthquakes in the year ended Dec 31 of those years in the table. 
Taking the interplate subduction quakes from north east to south west gave the following list: 1932, 1995, 1932, 2003, 1973, 1986, 1981, 1985, 1979, 1943, 1962, 1957, 1989, 1995, 1982, 1937, 1996, 1968, 1978, 1965, 1902, 1970, 1993, 1903, 1902, 1950, 1942.
Mexican intraplate events, both shallow and deep, listed chronologically: 1912, 1920, 1928, 1928, 1931, 1937, 1945, 1959, 1959, 1964, 1973, 1980, 1994, 1995, 1997, 1999, 1999.
