Mw 6.8 Near East Coast of Honshu, Japan
updated 1 June 2021 UTC

On 16 February 2015 a strong earthquake occurred near the east coast of Honshu, Japan at a depth of 15km. The seismic event occurred at 23:06:27 UTC and had an estimated moment magnitude (Mw) 6.8.

Planetary alignments occurred on the 13th and 14, which were the last in a series that also caused larger earthquakes on the 11th and 13th. The next alignments would not occur until the 22nd and 26th. A (strong) convergence of planetary alignments is almost guaranteed to cause larger seismic activity, well over magnitude 6. This can be one major to great seismic event, or multiple smaller but still strong to major events, as happened this time from the 11th to the 16th. Lunar geometry was relatively low (index 8) during this time but WPG peaks were also in abundance.
