Hayli Gubbi volcano eruption
The Hayli Gubbi volcano eruption in Ethiopia’s Afar region is one of the most significant geological events recorded in East Africa in generations. After nearly 12,000 years of dormancy, the volcano erupted on Sunday, launching an ash plume up to 14 kilometres into the atmosphere. The altitude, scale and international reach of the ash have triggered global aviation alerts, prompted scientific attention and renewed scrutiny of seismic activity in the Horn of Africa.
A Dormant Volcano with a Violent Return
Hayli Gubbi lies about 800 kilometres north-east of Ethiopia’s capital, Addis Ababa, near the border with Eritrea. It sits within the East African Rift, a highly active tectonic zone where the African and Arabian plates diverge.
Though classified as a shield volcano with modest elevation — around 493 metres above sea level — its location brings a latent potential for explosive behaviour when tectonic stress or magma pressure becomes sufficient.
According to the Global Volcanism Program, there is no record of any eruption from Hayli Gubbi during the Holocene epoch — until now. The 2025 eruption is therefore both rare and scientifically important.
How the Eruption Unfolded
Monitoring organisations, including the Toulouse Volcanic Ash Advisory Centre (VAAC), observed the eruption around 08:30 UTC on 23 November 2025. Satellite data showed a massive column of ash and volcanic gas soaring to 14 kilometres (about 45,000 ft).
Eyewitnesses in the nearby village of Afdera described the eruption as a sudden explosion followed by shock-waves. One resident said the sound was like a bomb; another said a pillar of ash and smoke dominated the sky. Ash promptly blanketed nearby settlements.
Although there was no magma flow or lava — the eruption appears to have been explosive, ejecting gases, ash and fine particulates rather than lava flows.
Ash Cloud Travel Path: Countries Affected
High-altitude winds carried the ash cloud across a vast region. Confirmed and reported affected territories include:
- Ethiopia — the eruption’s origin.
- Yemen and Oman, as ash drifted across the Red Sea and Arabian Peninsula.
- India, with ash reaching states such as Gujarat, Rajasthan, Punjab, Haryana, Delhi-NCR, Maharashtra.
- Pakistan, particularly northern regions; Pakistani meteorological authorities forecast ash to pass over the Arabian Sea region.
Satellite and atmospheric modelling suggest finer ash and gas may travel further east, potentially reaching parts of western China, though this remains forecast rather than confirmed.
Was Somaliland Affected?
Despite geographic proximity, there is no credible evidence that ash from Hayli Gubbi reached Somaliland. The observed plume headed north-east and east rather than west over the Horn of Africa.
Impact on Local Communities
The Afar region — home to pastoral and semi-nomadic communities — is already feeling the eruption’s consequences:
- Ash has covered grazing land around the village of Afdera, putting livestock forage at serious risk. Herders fear their animals may not survive without clean grazing or water.
- Tourism to the nearby Danakil depression, including its hot springs and salt flats, has been disrupted. Guides and travellers have been stranded due to poor visibility and ash-covered roads.
- Though there have been no verified human casualties or livestock deaths, long-term economic impacts are likely, especially if ash contamination persists or further eruptions occur.
Aviation Disruptions across Asia and the Middle East
Volcanic ash is notoriously hazardous for aircraft engines and safety. The ash plume from Hayli Gubbi has disrupted flight routes across continents:
- Several carriers including major Indian airlines cancelled or delayed flights.
- Aviation authorities, including India’s DGCA (Directorate General of Civil Aviation), issued advisories to avoid ash-affected airspace and instructed airlines to carry out additional safety checks.
- Air corridors over the Arabian Sea and northern India remained restricted until the ash cloud dissipated.
These disruptions highlight how a remote eruption in Africa can have an immediate global impact on travel and logistics.
Environmental and Health Concerns
Although the ash plume remains high in the atmosphere, experts warn of several potential risks:
- Fine volcanic ash particles and gases — especially sulphur dioxide — could eventually descend, degrading air quality in affected regions.
- If ash settles on soil or water supplies, it could harm agriculture, livestock and human health — particularly in communities already vulnerable due to harsh climate and limited resources.
- Public advisories have been issued for asthmatics and people with respiratory problems to limit exposure.
So far, ground-level effects appear limited, but scientists emphasise that continuous monitoring is essential as wind patterns evolve.
Scientific Significance: A Rare Window into Earth’s Inner Workings
The eruption of the previously quiet Hayli Gubbi offers an unprecedented opportunity for scientific study:
- Researchers can examine magma dynamics in a volcano considered dormant for the entire Holocene.
- The event challenges assumptions about volcanic “sleep”: inactivity over thousands of years does not guarantee future safety.
- The wide ash dispersal provides data on atmospheric transport of volcanic aerosols, emission of sulphur dioxide and global climate implications.
In combination, these factors make the Hayli Gubbi eruption one of the most important natural experiments of our times for volcanologists and climate scientists alike.
What to Watch Next
Experts and authorities are now focusing on:
- Monitoring seismic activity around Hayli Gubbi
- Tracking ground deformation — uplift or subsidence — which could hint at further magma movement
- Measuring gas emissions and ash output in case of renewed eruptions
- Updating aviation advisories and air-quality alerts for regions under the drifting plume
At this stage, the explosive phase appears to have ended. But volcanoes that awaken after millennia can behave unpredictably. Continued vigilance is crucial.
Conclusion
The Hayli Gubbi volcano eruption has transformed a remote mountain in Ethiopia into the centre of international attention. Its ash has crossed seas and continents, disrupted flights, threatened livelihoods and raised urgent scientific questions. As the world watches, this rare awakening reminds us that even long-silent volcanoes can stir unexpectedly — and that the consequences of nature’s deep rhythms can reach far beyond their point of origin.
