with the Aid of the Rotating CoreTheory
Seismic Activities in Relation to the Westward Drift of Secular Variation
The core and crust are separated by a magma zone, whereby the core rotates slightly slower than the crust, so that it drifts to the west. The difference in the rotation rates was defined by Heinrich Wehner to be 0.378 degrees per year (secular variation). The inner surface of the crust and outer surface of the core have peaks and valleys, similar to the surface of the earth. The earthquake zones are marked by particularly distinguished displacement zones in the crust. When one of these zones passes over a fold in the core, the increased pressure of the magma forms fissures (earthquakes).
If historical quakes are mapped according to the drift at approximately the same latitude for any specific year, the predominant mountain chain extending on the surface of the core can be identified. This makes it possible to predict the possible time and location of such a fold in the core. This law can be easily checked and proven on the basis of historical quakes.
For example the earthquake chronology from Hoff and Biot shows:
The devastating earthquake at Singanfu, the one-time capitol of CHINA, in 677 and its periodic repetition (677+952) in 1628, resulting also in a devastating quake. The same core fold caused the quake at Kai in JAPAN in 1549 and the terrible eruptions of the Japanese volcanos Siramayama and Hakusan in 1554; in 1822 a catastrophic earthquake occurred in SYRIA (destroying 40 towns) and in 1910 the devastating earthquake in ALGERIA.
Proof can be demonstrated with any large earthquake zone; wherever a large earthquake strikes, it is possible to find an accumulation of dislocated centers. It is also of interest to mention the major volcanic eruption and earthquake in the Minor Antilles in 1692 and 1693 (M.Misery, St. Kitts) and 82 years later a furious quake in the Kingdom of Mexico (1774). The historical eruption of La Soufriere on the Antilles island of Martinique took place on 18 May 1902 and the same period of time (83 years) later the major earthquake in Mexico on 23 September 1985.
