updated 26 September 2024

report

On 20 May 2015 a strong earthquake occurred at Santa Cruz Islands Region at a depth of 10 km. The seismic event occurred at 22:48:53 UTC and had an estimated moment magnitude (Mw) 6.8.

The estimated primary trigger of this seismic event is a convergence of lunar geometry on 15 and 18 May 2015.

On 15 May a planetary conjunction occurred with Earth between Mars and Saturn. On the same day opposing lunar semi-right angle geometry occurred with both planets. Lunar semi-right angle geometry also occurred with Mars and Neptune. A lunar conjunction occurred with Uranus.

On 18 May a New Moon converged with two lunar conjunctions involving Saturn and Mars. On 19 May a planetary conjunction occurred with Mars, Mercury and Saturn.

A cluster of strong earthquakes occurred on 19-20 May.
