Hayli Gubbi Volcano Erupts After Millennia, Disrupting Regional Air Travel
On November 23, 2025, the Hayli Gubbi volcano in Ethiopia’s Afar Region erupted after a long period of dormancy, sending ash plumes across the Red Sea and triggering flight disruptions that reached the Arabian Peninsula and South Asia. The event has drawn attention from scientists and public health officials concerned about environmental effects and respiratory risks.
Dr. Sophia Patel, a volcanologist at the University of London, described the eruption as “a significant event, given the volcano’s nearly 12,000‑year dormancy.” Her comment underscores the rarity of the activity at Hayli Gubbi, a shield volcano situated in the Erta Ale Range that had shown no signs of eruption until now. Although there are no direct historical records of previous eruptions, research conducted in 1969 and 1970 identified lava flows on the volcano’s southern flank that overran rock formations dated to roughly 8,200 years ago.
Dr. John Taylor, a geologist at the University of California, noted that “these findings suggested that the volcano had erupted sometime after 8,250 years ago, but the exact timing and frequency of these events were unknown.” The current eruption therefore offers a fresh data set for scientists aiming to clarify the volcano’s eruptive history. The ash cloud generated by the eruption has been tracked moving over the Red Sea, affecting nations such as Oman and Yemen.
Concerns about air quality have led Dr. Maria Rodriguez, a public health expert at the World Health Organization, to advise that “people in affected areas should take precautions to minimize their exposure to ash, such as wearing masks and staying indoors when possible.” Air travel has also been impacted. Several flights have been canceled or diverted as airlines avoid the ash plume, causing inconvenience for passengers and operators.
Dr. Brian Mitchell, a researcher at the National Oceanic and Atmospheric Administration, explained that “we are using satellite imagery and other tools to track the ash cloud and predict its movement.” This monitoring aims to assist authorities in adjusting flight routes and other activities that could be endangered by volcanic ash. Scientists view the eruption as an opportunity to improve understanding of volcanic processes.
The data gathered will contribute to broader knowledge about how eruptions affect the environment and human health. Dr. Patel emphasized that “advances in technology have greatly improved our ability to detect and respond to volcanic eruptions, but there is still much to be learned.” Beyond immediate hazards, the event highlights the need for sustained investment in monitoring and prediction technologies. Experts argue that the insights gained from studying Hayli Gubbi could inform strategies to mitigate the effects of future eruptions, benefiting the international community.
As the situation continues to evolve, officials urge caution. Dr. Taylor cautioned that “while the eruption is a significant event, it is essential to remember that volcanic activity is a natural part of our planet’s geology.” He added that supporting scientific research and monitoring efforts can help societies better understand and prepare for such phenomena, ultimately reducing associated risks.
