A strong earthquake struck waters near Vanuatu on October 24. The US tsunami warning system’s initial bulletin used magnitude 7.2 and a 10-kilometre depth, near 13.8° south and 165.7° east. Other seismic networks later published somewhat different magnitude estimates.
What is confirmed
The Hawaii bulletin did not issue a tsunami warning, advisory, watch or threat for that area. That is not a global assessment covering every Pacific coastline; countries publish their own notices. Earthquake magnitude alone also cannot establish damage or casualties without local reporting.
Why it matters—and what remains uncertain
Update the magnitude against a specific official event record and explain why preliminary estimates may change.
Context worth knowing
Differences between magnitude 7.2 and nearby values reported by other networks can reflect instrument revisions and analysis methods, rather than separate earthquakes. Readers need location, depth and issuing agency before comparing numbers. Vanuatu authorities are the relevant source for local impacts, while tsunami centres issue geographically specific advice.
What comes next
Editorial note: Figures and decisions reflect the cited reporting cutoffs. They may change; consult the latest official update before taking action.
