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 B).

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 A (highly significant p < .001). Strangely, 11 events happened in only five sequences (Sqs 30, 39, 48, 01 & 10) between March 11 and April 16 (5), as well as between July 14 and July 26 (6).
