A Sudden Eruption
On 23 November 2025, the Hayli Gubbi volcano in northern Ethiopia [[erupted::to break or burst out suddenly.]] without warning. It sent a huge cloud of ash and gas 14–15 km high into the sky.
This was the first time in recorded history that this volcano had ever erupted, which makes it very rare.
The ash cloud moved across several countries and caused problems for flights from Africa to the Middle East and even towards India. Many flights were delayed, changed, or cancelled.
People in nearby villages heard a powerful and loud blast, but no human deaths have been reported so far.
About Hayli Gubbi
Hayli Gubbi is in Ethiopia’s Afar Region, one of the hottest and lowest places on Earth. It is about 800 km from the capital city, Addis Ababa. It is a shield volcano, which means it has wide, gentle slopes made by thin, flowing lava.
Scientists think the volcano had been quiet for around 10,000–12,000 years, possibly since the end of the last Ice Age. There were no records of any past eruptions, so this was the first one known in all recorded human history.
The volcano is part of the East African Rift System, a region where the African continent is slowly splitting apart, allowing magma from deep underground to rise.
How Did It Erupt?
Scientists believe magma was building up under the volcano for thousands of years. In places like the Afar Region, hot material from the mantle melts rocks and forms magma. As magma moves upward, the gases inside it expand, like opening a shaken soda bottle.
When the pressure became too strong, the magma broke through the surface. This caused a powerful “sub-Plinian” eruption with a very tall ash column and strong [[explosions::the act of bursting]].
Satellite images before the eruption showed ground movement and gas coming out, which suggested magma was rising. But because the volcano had never erupted in modern times, scientists did not have enough information to predict it.
Effects on People, Land, and Air Travel
Thick ash covered villages within about 30 km of the volcano. Homes, plants, and water sources were covered in ash, and some families had to move away for safety.
Animals like goats and camels died after eating ash-covered plants.
The ash cloud made flying dangerous because ash can damage airplane engines and sensors. Many flights were rerouted or cancelled across Africa, the Arabian Peninsula, and parts of South Asia.
Scientists also found toxic sulfur dioxide gas, but early reports say the eruption is not likely to cause major global climate changes.
What Lies Ahead?
Scientists will keep watching the volcano to see if more activity happens.
The eruption gives experts a rare chance to study a volcano that was silent for thousands of years.
It also helps us learn how the African continent is slowly splitting and changing its shape over time.
Quick Revision
On 23 Nov 2025, Hayli Gubbi volcano in Ethiopia erupted for the first time ever, sending ash 15 km high.
It had been silent for over 10,000 years, so the eruption was unexpected.
Ash covered villages, animals died, but no humans were killed.
The ash cloud spread far, disrupting many flights.
The eruption helps scientists learn how Africa is slowly breaking apart.
