Mw 8.0 Haida Gwaii Region, Canada
updated 9 November 2022

On 22 August 1949 a great earthquake occurred in the Haida Gwaii region, Canada (Queen Charlotte Islands) at a depth of 10 km. The seismic event occurred at 04:01:18 UTC and had an estimated moment magnitude (Mw) 8.0.

Critical planetary geometry occurred on 15-16 August when Mercury made 90° angles, in particular with Earth and Mars. Strong seismic activity occurred with the next lunar peak on 17-18 August in Turkey (Mw 6.8) and Costa Rica (Mw 6.1). On the 20th Venus made a 90° angle with Earth and Uranus, which was followed by a high lunar peak on the 21st when the Moon aligned conjunct Mars and opposite Jupiter within 8 hours. The great earthquake occurred shortly after the high lunar peak.
