Mw 6.1 Vanuatu
updated 20 October 2021

On 18 October 2021 a strong earthquake occurred at Vanuatu at a depth of 100 km. The seismic event occurred at 07:26:52 UTC and had an estimated moment magnitude (Mw) 6.1.

Larger seismic activity was anticipated to occur from 17 to 19 October due to a convergence of critical planetary and lunar geometry, in particular on the 14th and 15th. While the anticipated magnitude range was higher 6 to 7 magnitude based on the critical geometry potential, the actual seismic activity did not exceed low 6 magnitude in this time-frame.
