Ethiopia’s Hayli Gubbi volcano erupted on November 23, 2025, for the first time in approximately 12,000 years, sending ash clouds 10-15 kilometers into the atmosphere. The volcanic ash rapidly spread eastward across the Arabian Peninsula and into South Asia, reaching India’s major metropolitan areas and triggering significant air travel disruptions. India’s DGCA issued precautionary advisories, prompting major carriers including Air India, IndiGo, SpiceJet, and Akasa Air to implement safety protocols. Airlines have cancelled flights, conducted aircraft checks, and rerouted operations to affected airspace. The ash cloud continues moving toward Nepal, Bhutan, and central China, raising concerns for regional aviation safety.
