A powerful eruption from Mount Lewotobi Laki-Laki on Indonesia’s Flores Island sent ash 18 km into the sky, disrupting air travel and affecting nearby villages. At least 24 international and domestic flights, including those between Bali, Australia, Singapore, and South Korea, were canceled. No casualties have been reported, but authorities recorded gas clouds with rocks and lava stretching 5 km. Officials warn of increased risks and may revise safety guidelines. Sunlight was briefly blocked in nearby areas due to heavy ashfall.
