Mw 7.8 Bonin Islands, Japan Region
updated 29 May 2021 UTC

On 30 May 2015 a major earthquake occurred at the Bonin Islands in the Japan region. The seismic event occurred at 11:23:03 UTC and had an estimated moment magnitude (Mw) 7.8.

This was the second forecast by Ditrianum, the first was the Nepal earthquake — also Mw 7.8 — a month earlier. Both earthquakes occurred after an Earth-Mercury-Mars alignment, but the overall planetary geometry around 28 May was considered much more critical, partially because of an equally critical Venus-Mercury-Neptune alignment. As a result, a warning was issued for seismic activity possibly up to magnitude 9. The initial estimate of this earthquake as reported by the media was magnitude 8.5. But it was later revised to Mw 7.8. The earthquake occurred at a record depth of 700km. For a detailed analysis of the planetary and lunar geometry involved, see the report below.
