“…The observed 11 year solar induced cyclic variation in the LOD is one of the evidences for such periodic forcing (Challinor, 1971;Curries, 1981). The other slower cycles reported by them are also confirmed in a recent work (Michelis et al, 2013) and probably also observed after very large individual solar flare (Danjon, 1962a, b;Gribbin and Plagemann, 1973;Stothers, 1989). It appears, therefore, that atmospheric Discussion Paper | Discussion Paper | Discussion Paper | Discussion Paper | disturbances/perturbations might some way or other is involved in catalyzing the small abrupt/instantaneous changes in the earth's rate of rotation.…”

Abstract. We studied the complex and non-stationary records of global earthquake employing the robust statistical and spectral techniques to understand the patterns, processes and periodicity. Singular Spectral Analysis (SSA) and correlation methods are used to quantify the nature of principle dynamical processes of global annual earthquake rates. The SSA decomposes the principle component of earthquake rates (first mode), which suggests that there is a linear increase in the yearly earthquake number from 1975 to 2005 accounting for 93% variance and may be identified with the earth's internal dynamical processes. Superimposed on this monotonic trend, there is an 11 years cyclic variation (second and third modes) accounting for 5% variance, which may corresponds to the well-known solar cycle. The remaining 2% higher order fluctuating components appears to be associated with artificial recharge and natural triggering forces (reservoir, tidal triggering etc.). The correlation study indicates that there is strong positive and negative correlation among the global earthquake rates with surface air temperature and sunspot numbers respectively. Interesting coupling mechanisms do exist, in which atmospheric circulations perturbed by the abrupt temperature variability might change the torques/momentum of inertia (earth's angular momentum) of the earth and thereby may offer the required inputs to trigger earthquake activities at the "critical phases".

“…These changes in the length of the day must be relatively prompt as they are known to track the seasonal changes of insolation [Lambeck and Cazenave, 1973]. They have also been detected with the same periods as the --•11-year solar cycle [Challinor, 1971;Currie, 1981] and some of the slower solar cycles as well [Link, 1961;Kiselev, 1981], and they have probably also occurred right after very large individual solar flares [Danjon, 1962a, b;Gribbin and Plagemann, 1973].…”

The historical record of large volcanic eruptions from 1500 to 1980, as contained in two recent eruption catalogs, is subjected to detailed time series analysis. Two weak, but probably statistically significant, periodicities of ∼11 and ∼80 years are detected. Both cycles appear to correlate with well‐known cycles of solar activity; the phasing is such that the frequency of volcanic eruptions increases (decreases) slightly around the times of solar minimum (maximum). The weak quasi‐biennial solar cycle is not obviously seen in the eruption data, nor are the two slow lunar tidal cycles of 8.85 and 18.6 years. Time series analysis of the volcanogenic acidities in a deep ice core from Greenland, covering the years 553–1972, reveals several very long periods that range from ∼80 to ∼350 years and are similar to the very slow solar cycles previously detected in auroral and carbon 14 records. Mechanisms to explain the Sun‐volcano link probably involve induced changes in the basic state of the atmosphere. Solar flares are believed to cause changes in atmospheric circulation patterns that abruptly alter the Earth's spin. The resulting jolt probably triggers small earthquakes which may temporarily relieve some of the stress in volcanic magma chambers, thereby weakening, postponing, or even aborting imminent large eruptions. In addition, decreased atmospheric precipitation around the years of solar maximum may cause a relative deficit of phreatomagmatic eruptions at those times.

“…As distinct from all earlier models of earthquakes [16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33], the theory of byuon allows to establish the deep-seated nature of physics of earthquakes, and therefore to predict place and time of an earthquake with the probability close to 100%.…”

To the foundation of a principally new short-term forecasting method there has been laid down a theory of surrounding us world’s creation and of physical vacuum as a result of interaction of byuons-discrete objects. The definition of the byuon contains the cosmological vector-potential Ag- a novel fundamental vector constant. This theory predicts a new anisotropic interaction of nature objects with the physical vacuum. A pe- culiar “tap” to gain new energy (giving rise to an earthquake) are elementary particles because their masses are proportional to the modulus of some summary potential A∑ that contains po- tentials of all known fields. The value of A∑ cannot be larger than the modulus of Ag. In ac- cordance with the experimental results a new force associated with A ejects substance from the area of the weakened A along a conical formation with the opening of 100° ± 10° and the axis directed along the vector A∑ . This vector has the following coordinates in the second equatorial coordinate system: right ascension α≈ 293°± 10°, declination δ≈36° ± 10°. The 100% probability of an earthquake (earthquakes of 6 points strong and more by the Richter scale) arises when in the process of the earth rotation the zenith vector of a seismically dangerous region and/or the vectorial potential of Earth’s magnetic fields are in a certain way oriented relative to the vector Ag. In the work, basic models and standard mechanisms of earth- quakes are briefly considered, results of proc- essing of information on the earthquakes in the context of global spatial anisotropy caused by the existence of the vector Ag, are presented, and an analysis of them is given
