MAJOR EARTHQUAKES IN SOUTH EAST FRANCE

APPENDIX 6

MAJOR QUAKES IN SOUTH EAST FRANCE:
1750-2000

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

SISMALP - French Alps Seismic Network released a comprehensive listing of 'historical quakes which have occurred in south-east (France) and the areas bordering on Switzerland and Italy for which the maximum intensity reached or exceeded VII' (see Table A this appendix). For the period to 1750 to 2000, SISMALP gave some 61 earthquakes for the south east region, of which 27 fell in the 9/56 year patterns as presented in Table B Appendix 18. This finding was highly significant at p < .001.

Curiously, 11 events happened in only five sequences (Sqs 39, 48 & 01) between March 11 to April 16, as well as between July 14 and July 26.
