Ethiopian volcano erupts after lying dormant for 12,000 years – Al Jazeera

Lead

Hayli Gubbi, a volcano in Ethiopia’s Afar region, erupted for several hours on Sunday morning, 24 November 2025, sending ash across the Red Sea toward Yemen and Oman. The long-dormant vent expelled a plume up to 14 km (nine miles) high and coated the nearby village of Afdera in ash. Local officials reported no human fatalities or livestock deaths so far, but residents and administrators warned of immediate economic and health impacts. Flights and broader regional air quality were affected as ash traveled beyond the Horn of Africa.

Key Takeaways

• The eruption occurred on 24 November 2025 at Hayli Gubbi in the Afar region, roughly 800 km (500 miles) northeast of Addis Ababa.
• Ash and volcanic smoke rose to about 14 km (nine miles) according to the Toulouse Volcanic Ash Advisory Centre (VAAC), with ash clouds tracked toward Yemen, Oman, India and northern Pakistan.
• No casualties have been confirmed by Afar authorities; village of Afdera was heavily dusted with ash and some visitors to the Danakil desert were stranded.
• The volcano’s cone reaches roughly 500 metres in elevation and sits on the East African Rift, a zone of active tectonics and crustal separation.
• The Smithsonian Institution’s Global Volcanism Program lists Hayli Gubbi as having no recorded eruptions in the Holocene, making this the first known activity in about 12,000 years.
• Local administrators say ashfall threatens grazing resources, putting livestock-dependent households at short-term economic risk.

Background

The East African Rift crosses northern Ethiopia and the Afar region, where continental plates are pulling apart and producing frequent volcanic and seismic activity. Rift dynamics create numerous volcanic edifices, fissures and geothermal fields; many vents in Afar are young in geological terms, though Hayli Gubbi had no documented Holocene eruptions until now. The Holocene began roughly 12,000 years ago after the last Ice Age, and volcanologists use that epoch to mark recent volcanic activity globally. Afar is sparsely populated, with communities largely reliant on pastoralism and seasonal tourism to the Danakil Depression, an area known for extreme landscapes and salt mining.

Volcanic ash can cause immediate problems for human health, infrastructure and animals: fine ash irritates eyes and lungs, contaminates water and pasture, and can smother crops and grazing plants. Regional aviation authorities monitor ash plumes because airborne ash can damage jet engines and instruments; the VAAC network issues advisories to reroute air traffic when ash reaches flight levels. Local administrations in Ethiopia have limited resources for mass evacuations and ash removal, raising concerns about how quickly aid can reach remote Afar communities. Past rift-related eruptions in the Horn and similar environments have produced wide-ranging ash dispersion despite limited local structural damage.

Main Event

On the morning of Sunday, 24 November 2025, residents near Afdera reported a sudden onset of intense seismic noise and a towering column of ash and smoke. The eruption lasted several hours; satellite and ground observations recorded ash lofted to approximately 14 km into the atmosphere. Ash settled over Afdera and surrounding settlements, leaving streets and corrals coated and strands of fine dust clinging to vegetation. Tourists and guides en route to the Danakil desert were stranded in ash-covered zones until conditions eased.

Local administrator Mohammed Seid told authorities that while there were no confirmed deaths, the fallout threatens pastoralists because grazing was buried under ash and available fodder is limited. Emergency teams and local leaders began advising residents to stay indoors where possible and to protect water supplies from contamination. Agencies monitoring volcanic ash tracked the cloud across the Red Sea toward Yemen and Oman, prompting aviation alerts and air-quality advisories in parts of the Arabian Peninsula. International monitoring centres, including the VAAC in Toulouse, issued updates that helped map the plume’s trajectory for regional responders.

The eruption is notable because Hayli Gubbi has no recorded Holocene activity in major volcanic records, so this event changes the local hazard profile. Field teams and remote-sensing analysts will need to reassess the volcano’s behaviour, physical changes to the cone and any new fissures in the area. At present, response efforts focus on immediate health guidance, protecting livestock feed where possible, and ensuring water sources remain usable for affected communities. Coordination between regional Ethiopian authorities and international monitoring agencies is underway to understand ash chemistry and the eruption’s likely duration.

Analysis & Implications

Ash reaching 14 km is high enough to enter the upper troposphere or lower stratosphere depending on atmospheric conditions, which increases the potential area of dispersal and the persistence of ash in the atmosphere. That height aligns with significant eruptions elsewhere that caused wide ash clouds and transboundary air quality impacts; for aviation, even smaller plumes can force route changes and cancellations. Because Hayli Gubbi had no recorded Holocene eruptions, local infrastructure and emergency planning may not have anticipated such an event, leaving communities more exposed in the short term.

The immediate economic impact will fall most heavily on pastoralists whose animals depend on open grazing; ash can coat vegetation and reduce palatability or nutrient access. If ash contaminates water supplies or silts irrigation channels, agricultural and household needs could be affected beyond the immediate ashfall zone. Tourism to the Danakil Depression, already seasonal and fragile, will suffer short-term disruption as visitors are stranded and operators reassess safety. Longer-term rehabilitation costs — cleaning ash from settlements, restoring grazing, and repairing any structural damage — will test regional budgets.

Geologically, the eruption reinforces the East African Rift’s active status and may signal continuing magma intrusion or renewed fissuring in Afar. Scientists will examine lava composition, gas emissions and seismicity to determine if this is a single, short-lived eruption or the start of more episodic activity. International monitoring collaboration will be crucial: satellite remote sensing, ground surveys and local observations together will provide the fastest, most reliable picture of evolving hazard levels. For neighbouring countries downwind, the event underscores the need for cross-border ash monitoring and communication protocols to protect aviation and public health.

Comparison & Data

The table summarizes immediate measured and reported metrics for the Hayli Gubbi eruption. While plume height and dispersal came from VAAC-tracked satellite and model products, duration is based on local reports and observational windows. These figures will be refined by field surveys and detailed satellite analyses in the coming days. Comparison with other modern eruptions shows Hayli Gubbi’s plume height is significant for regional ash transport and potential aviation impact but has not, to date, produced widespread structural destruction in nearby communities.

Reactions & Quotes

“It felt like a sudden blast hit the village,” a resident of Afdera said, describing the shock residents experienced when ash began to fall.

Local resident, Afar region

“No human deaths have been recorded so far, but ash has covered villages and grazing is compromised,” a regional administrator said as local teams mobilized to assess needs.

Mohammed Seid, Afar regional administration

“Hayli Gubbi has no prior recorded Holocene eruptions in our database, so this event requires a rapid reassessment of volcanic risk in the area,” an institutional notice indicated.

Unconfirmed

• Extent of livestock mortality: local officials report no confirmed animal deaths yet, but long-term losses from weakened grazing are possible and remain unverified.
• Duration of volcanic activity: initial reports indicate several hours of eruptive activity, but whether the volcano will produce further pulses or a longer phase of unrest is not yet known.
• Broader air-traffic impact in South Asia: ash was tracked toward parts of India and Pakistan, but the precise operational impact on flights in those countries remains to be confirmed by civil aviation authorities.

Bottom Line

The Hayli Gubbi eruption on 24 November 2025 is an uncommon event for a vent with no recorded Holocene activity and has immediate implications for nearby communities, regional aviation and cross-border ash management. While no human fatalities have been reported, the socioeconomic effects—especially for pastoralists—could unfold over weeks to months as ash disrupts grazing and water.

Rapid assessment, targeted relief for affected households, air-quality advisories and coordinated monitoring with international agencies will be crucial next steps. Scientific study of the eruption’s deposits, gas emissions and seismicity will help determine whether this marks a one-off event or a period of renewed volcanic activity in the Afar rift.
