Marc...Roger is looking at magnetic storms, not solar flares. If the CME is not earth-directed, it will not contribute to a magnetic storm, which is measured at Earth's surface (Kpn index). Need more information to tell what your results mean. For example, might there be a pattern where quakes are suppressed for 4 days then increase for the next 4? But, from what used to be posted on Earthwaves, it would be better to look at smaller volcanic regions like Long Valley and small magnitude quakes: the smallest that you are confident that the catalogue is complete. It's more interesting if you post graphs on this page because we can discuss them then, but if that is not easy feel free to send some attached to me: sorlien@centurytel.net

For non-volcanic areas, I guess you could make the case that if more small (say, M2 and 3 quakes) are triggered you would expect more large quakes also because some percent of the small quakes should cascade, but if triggering is favored in settings where M7+ quakes do not occur, then this will not be the case.
