Summary:

The Hayli Gubbi volcano in Ethiopia, dormant for at least 12,000 years, erupted on November 23, 2025. Scientists attribute the eruption to the ongoing tectonic activity in the East African Rift, where the African and Arabian plates are separating. This separation allows hot mantle rock to rise, melt, and feed magma into chambers beneath the volcano. The buildup of pressure eventually led to the eruption, sending ash high into the atmosphere. Due to the volcano’s remote location, scientists are relying on satellite images and ash samples to further understand the event, and current explanations are preliminary.

Long-Dormant Hayli Gubbi Volcano Erupts in Ethiopia

Afar Region, Ethiopia – November 25, 2025 – The Hayli Gubbi volcano, a shield volcano located in the remote Afar region of Ethiopia, has erupted after a period of dormancy lasting at least 12,000 years. The eruption, which occurred on November 23rd, sent plumes of ash into the atmosphere, prompting scientific investigation into the cause of the geological event.

Hayli Gubbi is part of the Erta Ale Range, situated along the East African Rift, a region where the African and Arabian tectonic plates are gradually pulling apart. Experts believe this tectonic activity is the primary driver of the eruption. As the plates separate, hot mantle rock rises, partially melts, and feeds magma into shallow chambers beneath the volcano. Over vast stretches of time, this magma accumulates, increasing pressure on the surrounding rocks. Eventually, this pressure finds a release through cracks and faults in the Earth’s crust, leading to the expulsion of gas-rich magma in the form of an eruption.

“We are still in the early stages of understanding this eruption,” said a geologist familiar with the matter. “The volcano is in a very remote and poorly monitored area, so we are relying heavily on satellite imagery and analysis of ash samples.” Scientists emphasize that current explanations are provisional and subject to change as more data becomes available.

The Hindu will continue to provide updates on the Hayli Gubbi eruption as more information is released.
