Ambae eruption stays localized as ash declines and gas persists; aviation warning remains local in Vanuatu
Ambae’s Lake Voui activity has eased somewhat, but the aviation alert remains and a strict exclusion zone around the vent is still in effect. Ash wanes while gas output and tremor persist, a reminder that conditions can shift quickly, especially with heavy rains raising the risk of lahars and ashfall downwind.
