Influences of Solar Cycles on Earthquakes

Influences of solar cycles on earthquakes

This paper inspects possible influence of solar cycles on earthquakes through of statistical analyses. We also discussed the mechanism that would drive the occurrence of increasing of earthquakes during solar maxima. The study was based on worldwide earthquakes events during approximately four hundred years (16002010).The increase of earthquakes events followed the Maxima of Solar cycle, and al...

Solar Flare Cycles

We present a review of different solar flare periodicity intervals. Our analysis includes a statistical investigation of flare occurrence and N-S hemispheric distribution over the last three 11-yr solar cycles (SCs 21-23, corresponding to the period 1976-2001). Moreover, we try to estimate if there is any connection between the flare activity and the strength of solar cycles. For that purpose, ...

Nonlinear analysis of solar cycles

In this paper, the recent improvement of the Wolf sunspot time–series by Hoyt and co-workers has been analysed with the Global Flow Reconstruction (GFR) method (Serre et al. 1996a and b). A nonlinear 4–dimensional chaotic model has been extracted from the data which captures the principal characteristic features of the sunspot group time–series. The hypothesis of interactions between magnetic m...

Earthquakes, influenza and cycles of Indian kala-azar.

It is suggested that previous data indicate 3 major epidemics of kala-azar in Assam between 1875 and 1950, with inter-epidemic periods of 30-45 and 20 years. This deviates from the popular view of regular cycles with a 10-20 year period. A deterministic mathematical model of kala-azar is used to find the simplest explanation for the timing of the 3 epidemics, paying particular attention to the ...
