“…An alternative hypothesis focuses on the role of crustal stress changes due to orbital oscillations of the inclination of the Earth causing a periodic increase in explosive volcanic activity (Jegen-Kulcsar et al, 2010;Bezverkhnii, 2017) and a perturbation in greenhouse gas emissions from the mantle (Bezverkhnii, 2014;Gilabert et al, 2021). On its turn, the orbital forcing of volcanism and volcanic gas output would play a significant role in determining the 41,000 years variations of the ocean water temperature (Bezverkhnii, 2019).…”

Tides and Volcanoes: A Historical Perspective

In this paper, we examine the origins and the history of the hypothesis for an influence of tidal forces on volcanic activity. We believe that exploring this subject through a historical perspective may help geoscientists gain new insights in a field of research so closely connected with the contemporary scientific debate and often erroneously considered as a totally separated niche topic. The idea of an influence of the Moon and Sun on magmatic processes dates back to the Hellenistic world. However, it was only since the late 19th century, with the establishment of volcano observatories at Mt. Etna and Vesuvius allowing a systematic collection of observations with modern methods, that the “tidal controversy” opened one of the longest and most important debates in Earth Science. At the beginning of the 20th century, the controversy assumed a much more general significance, as the debate around the tidal influence on volcanism developed around the formulation of the first modern theories on the origins of volcanism, the structure of the Earth’s interior and the mechanisms for continental drift. During the same period, the first experimental evidence for the existence of the Earth tides by Hecker (Beobachtungen an Horizontalpendeln über die Deformation des Erdkörpers unter dem Einfluss von Sonne und MondVeröffentlichung des Königl, 1907, 32), and the Chamberlin–Moulton planetesimal hypothesis (proposed in 1905 by geologist Thomas Chrowder Chamberlin and astronomer Forest Ray Moulton) about the “tidal” origin of the Solar System, influenced and stimulated new researches on volcano-tides interactions, such as the first description of the “lava tide” at the Kilauea volcano by Thomas Augustus Jaggar in 1924. Surprisingly, this phase of gradual acceptance of the tidal hypothesis was followed by a period of lapse between 1930 to late 1960. A new era of stimulating and interesting speculations opened at the beginning of the seventies of the 20th century thanks to the discovery of the moonquakes revealed by the Apollo Lunar Surface Experiment Package. A few years later, in 1979, the intense volcanism on the Jupiter’s moon Io, discovered by the Voyager 1 mission, was explained by the tidal heating produced by the Io’s orbital eccentricity. In the last part of the paper, we discuss the major advances over the last decades and the new frontiers of this research topic, which traditionally bears on interdisciplinary contributions (e.g., from geosciences, physics, astronomy). We conclude that the present-day debate around the environmental crisis, characterized by a large collection of interconnected variables, stimulated a new field of research around the complex mechanisms of mutual interactions among orbital factors, Milankovitch Cycles, climate changes and volcanism.

“…Дополнительное усиление этих колебаний обусловлено обратными связями ледниковых циклов с вариациями CO 2 и альбедо земной поверхности [6][7][8] и, по-видимому, уровня океана. так как ритмы орбитального масштаба в движении магмы проявляются в подводной вулканической активности, продуцирующей тепломассоперенос, эмиссию парниковых газов в разломах MOR (с вовлечением их в глобальный углеродный цикл), то можно полагать, что включение в модель CLIMBER-2 [8,24] «геодинамического блока», моделирующего климатические эффекты, связанные с подводной вулканической активностью, позволит улучшить результаты моделирования изменений климата плейстоцена.

100,000-year rhythmicity of paleoclimate variations, that aroused in the Late Pleistocene, can be linked with corresponded long-term oscillations of insolation and seafloor volcanism, forced by gravitational forces in Solar system. This conclusion is based on wavelet analysis of variations of the earth’s orbit eccentricity, different paleoclimatic characteristics, and their known spectral estimates and seafloor volcanism data.
