The month's largest event in Vanuatu was a magnitude 7.3 earthquake near Port-Vila, Vanuatu on 17 December 2024 at 01:47 UTC. A magnitude 7.3 earthquake radiates roughly 1.3 million tons of TNT equivalent in seismic energy.

73% of events here are shallow (under 70 km), 27% intermediate (70–300 km) and 0% deep-focus (over 300 km). The mix is dominated by shallow crustal events, with a minority of intermediate-depth activity.

By band, the catalogue holds 6 in the magnitude 4 range, 4 in the magnitude 5 range, 1 in the magnitude 7 range.
