Mw 7.8 Northern Xinjiang, China
updated 4 June 2021 UTC

On 22 December 1906 a major earthquake occurred in Northern Xinjiang, China at a depth of 15km. The seismic event occurred at 18:21:11 UTC and had an estimated moment magnitude (Mw) 7.8.

Five planetary alignments from the 17th to the 21st preceded the earthquake, most notably Mercury-Sun-Saturn, Venus-Sun-Uranus and Sun-Venus-Neptune, the last two of which were a decisive factor. Lunar geometry on the 16th was very similar to that of August and September before the great earthquakes, again resulting in a high lunar peak. It tells us that Earth was again closely alignment with Jupiter and Uranus. It would have made the 19th already very critical, but decisive in the timing was probably Venus' alignment with the Sun and Neptune on the 21st. A similar 'delay' occurred in September 2018. Two WPG peaks on the 18th and 21st preceded the earthquake, but they were likely a less decisive contributor.
