Quantic seismology (anthological synthesis)

After individuated 3 periods P (superior to 29 days and mod. 15) among the principal seismic intensities, and also of the 1.st in comparison with the 4.th, I choose that with the maximum number of under-multiples; one verify that the resultant p is not always the maximum among that considered. In Pascal language, the algorithm reduces notably in comparison with the electronic sheet, used for data base; but by the logical-analytical details seem better Mathematica, like in the example, using Date Difference functions... & PrimeOmega.... The agreements on the periods are to be considered satisfactory, but by great amplitudes of intensity it be necessary to consider, besides the Planets Conjunctions and to the Solar Flares, pseudo-gravitational field -∂Ψ/∂r of till now neglected particles (planetary WIMP).
