Mw 6.6 Near North Coast of Papua, Indonesia

updated 20 February 2025

report

On 24 September 2015 a strong earthquake occurred near the north coast of Papua, Indonesia at a depth of 25 km. The seismic event occurred at 15:53:28 UTC and had an estimated moment magnitude (Mw) 6.6.

The estimated primary trigger of this seismic event is critical lunar geometry on 23 September 2015.

On 23 September a tight convergence of semi-right angle lunar geometry occurred with Jupiter and Neptune. In September 2015 Earth moved between Jupiter and Neptune, which resulted in critical lunar geometry with both outer planets. Most notably, this type of lunar geometry occurred shortly before the great earthquake on 16 September.
