Puzzle of World’s Earthquake Cycle in Connection with Hale Cycle

Abstract

Aysegul YILMAZ*

In present, we plot Number of World’s Earthquakes NWEQK vs Year as done in previous study, but by extending the period of year from 1976 to 2019 [1,2], i.e., period of two consecutive Hale Cycles .We find that parts of our present plotting during odd-numbered Solar Cycles and during even-numbered Solar Cycle corresponding to both Hale Cycle of our interest, have the same number pieces with similar shapes, respectively. However, their sizes get larger from first Hale Cycle to second Hale Cycle in sequence. Referring to pieces of our present plotting, we find local variations in NWEQKs per Year corresponding to the period of Top Flat Galactic Cosmic Ray (GCRs)Maxima belonging to both Hale Cycles correlate with Solar Polar Field outward in North to South direction (SPFNS), but anti-correlate with T.F.GCR. And local variations corresponding to period of Sharp GCR Maxima correlate with Shrp GCR, but anti-correlate with Solar Polar Field inward in the South (SPFNS) [3]. On the other, general trends of NWEQKs per Year during whole T.F.GCR maxima period except for the years of T.F.G.R – peak value and during Shrp GCR period are to incline (decline) as both of SPFNS Maxima and Shrp Maxima incline (decline), respectively. In terms of effective SPF of both kind of polarities and GCR- effects of both kinds we propose, we define a World’s Earthquake Cycle in connection in Hale Cycle which ascends from one Hale Cycle to the next one by means of our present plotting.
