Key Takeaways
- Volcanic ash from Ethiopia’s Hayli Gubbi eruption is drifting towards India, threatening air travel.
- The DGCA has issued flight safety advisories, warning airlines to avoid affected regions.
- Ash clouds are forecast to sweep across central India, including Delhi, overnight.
India is preparing for potential air travel disruption as volcanic ash from the November 23, 2025, eruption of Ethiopia’s Hayli Gubbi volcano moves toward the mainland. The ash plume poses a significant risk to aircraft engines.
DGCA Issues Safety Advisories
The Directorate General of Civil Aviation (DGCA) has issued urgent advisories, instructing airlines to avoid altitudes and regions affected by the ash cloud. Volcanic ash contains abrasive, glass-like particles that can melt inside jet engines, stick to turbine blades, and cause engine failure.
Airlines are also required to report any suspected ash impact, such as unusual engine performance, cabin smoke, or strange odours. Airports have been directed to inspect runways for ash contamination and to suspend or restrict flight operations if necessary.
Ash Cloud Path and Forecast
After the initial eruption ceased, large smoke plumes were observed over Ethiopia. The ash cloud then travelled over Yemen and Oman before entering the Indian subcontinent via Western Rajasthan on Monday evening.
The ash is forecast to move northeast overnight, sweeping across central India. It is expected to cross Delhi around midnight and subsequently affect parts of Uttar Pradesh, Bihar, Sikkim, and Arunachal Pradesh.
