A Sleeping Giant Wakes Up
The world of geology got a major surprise. A volcano in Ethiopia has erupted (Ethiopian volcano). This volcano is called Hayli Gubbi. The surprise is that it had been quiet for an extremely long time. Scientists believe the volcano last erupted about 12,000 years ago. That is a huge gap in time. Ethiopian volcano
The eruption happened suddenly on a Sunday in November 2025. It sent a massive cloud of ash high into the sky. This cloud traveled thousands of kilometers. It created problems for flights in the Middle East and South Asia. This rare event brings both scientific excitement and danger. It shows the incredible power hidden under the Earth’s surface. It also brings new dangers to people living nearby. We must now look closely at what happened and what it means for the world. This is a very important moment in geological history. Ethiopian volcano
A Silent Giant Awakens: The Hayli Gubbi History Ethiopian volcano
The Hayli Gubbi volcano is in a very remote area. It sits in Ethiopia’s Afar region. This region is about 800 kilometers northeast of the capital, Addis Ababa. It is close to the border with Eritrea.
The volcano is a type called a shield volcano. This means it is wide with gentle slopes. It was built up over a very long time by thin, runny lava flows. Hayli Gubbi stands about 500 meters tall. It has been a quiet giant for millennia. Ethiopian volcano
The last time this volcano was active was near the end of the last Ice Age. Scientists call this period the start of the Holocene epoch. The Holocene began about 12,000 years ago. Geologists have studied this volcano for many years. They had no known record of any eruptions during the entire Holocene period. For all practical purposes, this volcano was considered dormant. That means it was sleeping.
The Heart of the Rift Valley: Why It Exists Ethiopian volcano
To understand the eruption, we must look at where Hayli Gubbi sits.
The volcano is in a very special place on Earth. It is part of the East African Rift System. This is a massive break in the Earth’s crust. It is a place where the Earth is slowly tearing itself apart.
The Rift Valley is where two of Earth’s great tectonic plates meet. These plates are the Nubian Plate and the Somali Plate. They are moving away from each other. They move at a very slow speed. This movement pulls the Earth’s crust thin. Think of it like stretching a piece of dough until it tears. Ethiopian volcano
Hayli Gubbi is right in the middle of this action. It is in the Afar Depression. This area is also known as the Afar Triple Junction. It is where three different rifts meet. This makes it one of the most geologically active and intense places on the planet. This stretching and thinning of the crust makes it easy for hot rock, or magma, to rise from deep inside the Earth. The heat comes from a mantle plume located beneath Afar. This is a source of intense heat. Ethiopian volcano
An Explosive Start: The Eruption Event
The eruption of Hayli Gubbi was not a gentle lava flow. It was an explosive event. Volcanologists describe it as a Sub-Plinian eruption. This means it was a powerful burst. It involved a strong vertical column of gas and ash. Ethiopian volcano
The eruption began on Sunday morning and continued for several hours. It released an enormous plume of smoke and ash. This plume rose to an amazing height. It went up to 14 kilometers, or about 45,000 feet, into the atmosphere. This is higher than most commercial airplanes fly.
The plume was not just smoke. It was a mix of dangerous materials:
- Ash Particles: These are tiny fragments of rock and hardened volcanic glass. They are sharp and abrasive.
- SO_2 Gas: This is sulfur dioxide gas. This gas can create haze and acid rain. It also affects air quality.
- Glass Shards: These very fine, tiny pieces of volcanic glass pose a huge risk to aircraft engines.
Locals in the Afar region reported a terrifying start. A resident named Ahmed Abdela said he heard a loud sound. He felt a shock wave. He said, “It felt like a sudden bomb had been thrown with smoke and ash.” The intense explosion also caused earthquakes or tremors. These were felt in towns far away from the volcano. The massive power of this ancient volcano took everyone by surprise.
A Global Reach: Aviation Disruption Ethiopian volcano
The ash cloud did not stay in Ethiopia. It was carried by strong, high-altitude winds. The cloud quickly traveled across the Red Sea. It went over Yemen and Oman. Then it moved across the Arabian Sea. The ash plume even reached India and northern Pakistan. This global travel caused major problems for air travel. Ethiopian volcano
Volcanic ash is a huge danger to airplanes. Jet engines suck in air. The ash contains tiny particles of silica, which is like sand. At the high temperatures inside a jet engine, this silica melts. It turns into a sticky, glass-like substance. This substance then clogs the engine’s parts. It can cause a sudden power loss, or flameout. It is also a danger to aircraft sensors and windshields.

Because of this great risk, aviation authorities quickly issued warnings. The Toulouse Volcanic Ash Advisory Centre (VAAC) tracked the plume’s movement. In response, countries like India issued advisories. The Directorate General of Civil Aviation (DGCA) told airlines to change their routes. They had to avoid the areas where the ash cloud was present.
Impact on Local Communities: Herders and Ash
While the aviation problems were global, the most direct impact was local. The Hayli Gubbi volcano is in a remote area. But many small villages are nearby. The closest village, Afdera, was covered in thick ash and dust.
A local administrator, Mohammed Seid, reported that luckily, no human lives were lost right away. He also reported no major loss of livestock. However, the eruption will cause economic problems for the local community. The people in the Afar region are mainly livestock herders. They depend on their animals for their livelihood.

The thick ash covering the land is a big problem. The ash has settled on grazing fields. This means the animals have little clean food to eat. This puts the herders’ income at risk. Ash can also contaminate water sources. The long-term effects on the soil and water will be a challenge for the region. People who were heading to the Danakil desert, a nearby tourist spot, were also stranded in the ash-covered villages. The local authorities are now working to help the residents and assess the full damage. They are also worried about more seismic activity in the area. Ethiopian volcano
What Scientists Are Learning
The Hayli Gubbi eruption is a scientific goldmine. It is a very rare chance to study a volcano that was silent for a full geological epoch. Scientists around the world are now paying close attention to the Afar region.
The eruption proves a key point: a dormant volcano is never truly dead. The eruption came without a strong, public warning. This suggests that the processes that wake up a volcano can happen quickly and deeply below the surface. Geologists are studying satellite images. They are looking for signs of the changes that led to the eruption. These are tracking the amount of 2 gas released. They are also looking for new ground fissures or lava flows that might have happened. Ethiopian volcano
A Sign of Earth’s Power
The eruption of Ethiopia’s Hayli Gubbi volcano is a huge geological event. It broke a silence that lasted 12,000 years. It showed the world the immense power of the East African Rift. The eruption was explosive. It sent a massive ash cloud high into the sky. This cloud disrupted flights over three continents. It also put the livelihoods of poor local communities at risk.
The immediate crisis involves managing the ash plume’s threat to aviation and helping the herders in the Afar region. The long-term challenge is for scientists. They must now monitor Hayli Gubbi very closely. They need to figure out if this was a one-time event or the start of a new period of activity. This volcano’s sudden return to life reminds us that the Earth is always changing. It shows us that we must always be ready for the unexpected power of nature. Ethiopian volcano
