On 16 March 2022 a major earthquake occurred near the East Coast of Honshu, Japan at a depth of 49 km. The seismic event occurred at 14:36:32 UTC and had an estimated moment magnitude (Mw) 7.3. It was preceded by a Mw 6.4 tremor 2 minutes earlier.
A major earthquake warning was issued on the 11th, primarily due to the Venus-Mercury-Neptune conjunction, which is known to precede major earthquakes (high 7 to 8 magnitude). The Earth-Sun-Neptune conjunction on the 13th played an additional role. In addition, there was a convergence of critical planetary geometry involving Mercury and Venus with outer planets from the 13th to the 15th. On the 14th a warning was issued for possible larger seismic activity due to a lunar conjunction with Mars in particular. See also the Telegram posts below.
