Astronomy chronograph of strong earthquakes and volcanism

The role of tidal effects on geospheric shells from the Moon, the Sun, Venus, Mars and Jupiter is examined. The impact of specific configurations of the Sun and the planets (in the line of apsides, equinoxes, solstices) on the catastrophic geophysical processes such as anomalous seismicity and volcanism.

The histogram distributions of earthquakes and volcanic eruptions, depending on the distance Earth-Sun, the ecliptic latitude of the Moon, the geocentric longitude differences of Sun and Venus or Mars are adduced. This astrogeophysical approach allowed to identify global relationships of planetary nature.

Particular attention is paid to the analysis of well-known and paradoxical cases of and mutual influence of seismic and volcanic activity:

- A powerful earthquake in Chile (1835.), followed by the awakening of several volcanoes;

- Tunguska phenomenon(1908) as a volcanic earthquake with advanced gas phase and high-altitude undermine the degassing of hydrogen-methane stream from the crater of Kulikovskii paleovolcano;

- Dramatic activation in mid-1908 of Mount Etna in Italy and Erebus in Antarctica and subsequent Messina earthquake with the formation of a powerful tsunami and ejection of giant steam-gas jet height of 8 km on the pass between Erebus and Mount Baird;

- Unexpected and powerful awakenings of Kamchatka after a swarm of earthquakes volcanoes Bezymyannyi (1956) and caldera of the Academy of Sciences (1996).

The work was carried out with the financial support of the Ministry of education and science of the Russian Federation (in accordance with the requirements of the State contract ?14.577.21.0109).
