This paper is devoted to modeling of the dynamics of the temperature regime of mud volcano gryphons. The model is elaborated
on the basis of a nonstationary equation of thermal conductivity with a convective component and describes well the observed
regularities of thermal regime of South Sakhalin mud volcano gryphons. It is shown that anomalous changes in the temperature
of the water-mud mixture after the Gornozavodsk and Nevelsk earthquakes in 2006–2007 are caused by variations in motion velocity
of the mixture in the supply pipes of gryphons. It also has been shown that influx of deep geofluids cannot be considered
as the main reason for thermal anomalies. 相似文献

For more than a decade, the global network of GPS stations whose measurements are part of the International GPS Service (IGS) have been recording cyclic variations in the radius vector of the geodetic ellipsoid with a period of one year and amplitude of ~10 mm. The analysis of the figure of the Earth carried out by us shows that the observed variations in the vertical component of the Earth’s surface displacements can induce small changes in the flattening of the Earth’s figure which are, in turn, caused by the instability of the Earth’s rotation. The variations in the angular velocity and flattening of the Earth change the kinetic energy of the Earth’s rotation. The additional energy is ~1021 J. The emerging variations in the flattening of the Earth’s ellipsoid lead to changes in the surface area of the Earth’s figure, cause the development of deformations in rocks, accumulation of damage, activation of seismotectonic processes, and preparation of earthquakes. It is shown that earthquakes can be caused by the instability of the Earth’s rotation which induces pulsations in the shape of the Earth and leads to the development of alternating-sign deformations in the Earth’s solid shell. 相似文献
