Green earthquake (Magnitude 6.1M, Depth:188.148km) in Vanuatu 16/08/2026 03:20 UTC, 5 thousand in MMI IV

Summary

Single-source GDACS detection — awaiting independent verification. A magnitude 6.1 earthquake at a depth of 188 km struck Vanuatu on 16 August 2026, with an estimated 5,000 people exposed to MMI IV shaking. The significant depth suggests a low probability of major surface damage, though the event warrants monitoring for any secondary effects.

Supply chain impact

No commodities or chokepoints are directly mapped to this event; second-order effects depend on how the situation escalates. If confirmed, the deep-focus nature of the quake typically limits severe infrastructure disruption, but localized impacts on regional logistics in Vanuatu could still emerge.

Watch points

• Aftershock activity or reports of damage to regional port infrastructure in Vanuatu, which could temporarily disrupt transshipment or inter-island supply routes.
• Any tsunami warnings or advisories issued by regional authorities, which would indicate a higher risk to coastal logistics assets.
• Official damage assessments from Vanuatu’s National Disaster Management Office, particularly regarding road connectivity and airfield operability.
