SUMMARY

The Loyalty Islands east of New Caledonia are experiencing significant seismic activity, highlighted by a magnitude 6.8 earthquake followed by multiple aftershocks, including a magnitude 6.1 and a magnitude 6.6. Additionally, a magnitude 6.3 earthquake occurred in the northern Banda Sea, Indonesia. Tsunami waves have been detected in New Caledonia and Vanuatu following a 7.0 magnitude earthquake, with the Pacific Tsunami Warning Center forecasting waves up to 1 meter above the high-tide mark. No reports of damage have been confirmed as of the latest updates.

PREREQUISITES
  • Understanding of seismic activity and earthquake magnitudes
  • Familiarity with tsunami warning systems and their implications
  • Knowledge of the geographical context of the Loyalty Islands and surrounding regions
  • Basic comprehension of earthquake monitoring tools and resources
NEXT STEPS
  • Research the USGS Earthquake Event Page for real-time earthquake data

Dave, please tell the ground to stop shaking. It's considered extremely rude.

Tsunami waves have been detected in New Caledonia and Vanuatu after 7.0 magnitude earthquake struck.

Reuters reported the waves hit at 12.35pm (NZT). There was no word on damage.

The Pacific Tsunami Warning Center said waves as high as 1 metre (3.3 ft) above the high-tide mark were forecast to hit New Caledonia and smaller waves were expected in Vanuatu.

I am sure Dave will have his graphs detecting the quake.
