So in essence, they had the warning there was a small chance that something would happen and it was ignored because it was a small chance.
therefore, not of any more relevance that an Astrologer pointing out there is chance that something could happen within a time frame.
Aside from the fact that the follow on event happened within the seismologists' timeframe, and within the 100 mile region pinpointed, vs it not happening within the astrologer's timeframe who didn't even specify a hemisphere.
And I'll make equivalent the theory that a chance of an earthquake being a foreshock as being 'ignored' to the question 'when did you stop beating your child?' Both imply things that didn't happen.
