Synopsis
As an ash cloud from Ethiopia's Hayli Gubbi volcano drifts over North India, experts assure that it won't affect air quality. Learn how aviation safety measures are being implemented amidst this unusual atmospheric occurrence.
Key Takeaways
- The ash cloud from Ethiopia is primarily at mid-levels of the atmosphere.
- No significant impact on air quality is expected across most regions in India.
- Airlines are being advised to modify flight operations due to safety concerns.
- Elevated sulphur dioxide levels may occur in hilly areas.
- Continuous monitoring of the ash plume is being conducted by authorities.
New Delhi, Nov 25 (NationPress) A significant ash cloud originating from the Hayli Gubbi volcano in northern Ethiopia has traversed the Arabian Sea and entered India by Monday night, currently moving over portions of north India. This development has prompted aviation authorities to issue guidelines for airlines regarding safety. Nevertheless, experts have stated that it is not anticipated to influence air quality since the ash cloud predominantly resides at mid-levels of the atmosphere.
The volcanic eruption, which took place on Sunday following a long period of dormancy, released a thick plume that journeyed across the Red Sea towards Yemen and Oman before heading towards the Indian subcontinent.
As of 11 p.m. on Monday, the ash plume had already entered Indian airspace and was detected over Delhi, with its trajectory expected to continue towards Punjab and Haryana throughout the night and into Tuesday.
This uncommon atmospheric phenomenon prompted the Directorate General of Civil Aviation (DGCA) to release a comprehensive advisory to airlines. They are urged to avoid specified areas affected by volcanic ash and adhere to flight level restrictions.
Airlines have been advised to adjust flight planning, routing, altitude selection, and fuel calculations based on the latest Volcanic Ash Advisories (VAAs).
The DGCA's guidance follows reports of rerouted and delayed flights as aircraft operators seek safe navigation around affected regions.
Volcanic ash presents a critical hazard to aviation, particularly for jet engines, as ash particles can melt within engines and inflict serious damage.
IndiaMetSky Weather provided an explanation of the situation on X, indicating that the plume currently contains sulphur dioxide (SO₂) along with low to moderate concentrations of volcanic ash.
In their post, IndiaMetSky Weather noted: “The ash plume primarily comprises sulphur dioxide with low to moderate amounts of volcanic ash. It extends from the Oman–Arabian Sea region into the plains of North & Central India. It will not impact AQI levels but may affect SO₂ levels in the Hills of Nepal, Himalayas, and adjacent Terai belt of Uttar Pradesh as some material will collide with the hills before drifting into China.
“There are minimal chances of ashfall over plains, but some areas may experience minor occurrences. NO IMPACT ON AQI LEVEL AT SURFACE LEVEL IS EXPECTED,” the post added.
“The plume will gradually continue drifting over Delhi, Haryana, and the Rajasthan region. Once again, this phenomenon is situated at mid-levels of the atmosphere, implying no significant surface impact aside from potential changes in flight routes and a slight chance of particles reaching the surface,” it concluded.
Meteorologists stress that the ash cloud primarily exists at mid-levels, indicating it is unlikely to affect surface air quality in most parts of India. However, elevated sulphur dioxide levels may be observed in the hills of Nepal, the Himalayas, and Uttar Pradesh's Terai belt as the plume interacts with the mountainous terrain.
The plume is predicted to gradually drift westward and diminish in intensity, but authorities will continue to monitor its progression closely. Travelers are encouraged to consult with airlines for the latest flight schedules, as temporary disruptions may persist until the plume dissipates.
Point of View
It’s crucial to remain informed about atmospheric events like the ash cloud from Ethiopia. While there might be concerns regarding air quality, expert evaluations suggest minimal impact on surface conditions across most regions of India. Continuous monitoring and timely advisories from authorities are essential to ensure public safety and smooth air travel.

Frequently Asked Questions
What caused the ash cloud over North India?
The ash cloud was caused by the eruption of the Hayli Gubbi volcano in northern Ethiopia, which released a thick plume that traveled across the Arabian Sea to India.
Will the ash cloud affect air quality in North India?
Experts indicate that the ash cloud is primarily located at mid-levels of the atmosphere, so it is not expected to impact surface air quality significantly.
What safety measures are airlines taking in response to the ash cloud?
Airlines have been advised by the Directorate General of Civil Aviation (DGCA) to avoid designated volcanic ash-affected areas and adjust flight planning and routing as per the latest Volcanic Ash Advisories.
Is there any risk to passengers traveling in the affected regions?
While there may be minor disruptions in flight schedules, the risk to passengers is minimal as the ash cloud does not pose a significant threat to air quality or safety.
What should travelers do if their flights are affected?
Travelers are advised to check with airlines for updated flight schedules and remain informed about any changes due to the ash cloud.
