When Was Mount Kilimanjaro Last Eruption ? Mount Kilimanjaro is the tallest mountain in Africa, attracting thousands of climbers and adventurers every year. But while it’s known for its snow-capped peak and stunning landscapes, many are unaware that Kilimanjaro is a dormant stratovolcano. With three volcanic cones—Kibo, Mawenzi, and Shira—Kilimanjaro has a rich geological history. This raises the question: When was Mount Kilimanjaro’s last eruption, and could it erupt again?
In this guide, we’ll explore Kilimanjaro’s volcanic past, what makes it unique, and whether there’s any risk of future eruptions.
When Was Mount Kilimanjaro Last Eruption : Mount Kilimanjaro’s Volcanic Cones
Mount Kilimanjaro is made up of three distinct volcanic cones:
- Kibo: The highest and only dormant cone, standing at 5,895 meters (19,341 feet). This is where the iconic Uhuru Peak is located.
- Mawenzi: The rugged and eroded second-highest cone at 5,149 meters (16,893 feet), which is extinct.
- Shira: The oldest cone, now a plateau after having collapsed millions of years ago. Shira is also extinct.
Kibo is the main focus when it comes to Kilimanjaro’s volcanic activity, as it’s the only one that could potentially erupt again.

When Was Mount Kilimanjaro Last Eruption : When Was Kilimanjaro’s Last Eruption?
Mount Kilimanjaro’s last significant eruption occurred approximately 360,000 years ago. This eruption formed the towering Kibo cone, which is the central summit we see today. Following that, minor volcanic activity continued for thousands of years, with the most recent lava flow believed to have taken place 200,000 years ago.
Although Kibo is classified as a dormant volcano, meaning it has the potential to erupt again, it has been inactive for hundreds of thousands of years.

When Was Mount Kilimanjaro Last Eruption : Will Mount Kilimanjaro Erupt Again?
The possibility of Kilimanjaro erupting again remains low but not impossible. Dormant volcanoes are considered to have the potential to erupt, but no volcanic activity has been recorded at Kibo in modern times.
Signs of Dormancy
- No Recent Activity: Kilimanjaro has shown no significant signs of volcanic activity for millennia. There are no observable tremors, gas emissions, or other indicators that would suggest an impending eruption.
- Geological Studies: Research and geological surveys conducted in the region show no evidence that the magma chambers beneath Kilimanjaro are currently active.
While future eruptions cannot be completely ruled out, experts agree that the likelihood of an eruption occurring in the foreseeable future is extremely low. Climbers and residents of the surrounding area can feel safe enjoying the beauty of Kilimanjaro without fear of an eruption.

When Was Mount Kilimanjaro Last Eruption : How Kilimanjaro’s Volcanic History Shaped Its Landscape
Kilimanjaro’s volcanic activity played a major role in creating the breathtaking landscapes that trekkers experience today. The eruptions of Kibo, Mawenzi, and Shira over millions of years have shaped the mountain into the stratovolcano it is now.
Kibo’s Caldera and Crater
At the top of Kibo is a caldera, formed after the last major eruption. The Reusch Crater sits inside this caldera, and at its center lies the Ash Pit, a stark reminder of Kilimanjaro’s volcanic past. The caldera and crater offer a unique geological experience for those who reach Uhuru Peak.
Shira Plateau
The Shira Plateau is a vast, flat area formed from the collapse of the Shira cone after it became extinct. Today, the plateau is home to unique wildlife and plants that thrive at high altitudes, offering spectacular views for climbers on the Lemosho and Shira routes.

5. Climbing Kilimanjaro: What Climbers Should Know About the Volcanic Terrain
Although Kilimanjaro is a dormant volcano, the effects of its volcanic past can still be seen throughout the mountain’s ecosystems and terrain. Climbers will pass through multiple ecological zones, each shaped by volcanic activity.
Ecological Zones
- Rainforest Zone: The lower slopes of Kilimanjaro are covered in lush rainforests, thanks to the rich volcanic soil that fosters plant growth.
- Alpine Desert Zone: As you ascend, the landscape becomes barren, a result of past volcanic eruptions that left behind rocky, desert-like terrain.
- Summit Zone: At the top, climbers are greeted by glaciers and the remnants of Kilimanjaro’s volcanic activity, including the crater and ash pit at Kibo.

When Was Mount Kilimanjaro Last Eruption : Impact of Climate Change on Kilimanjaro’s Snow and Glaciers
While the volcanic activity on Kilimanjaro has long since subsided, climate change has dramatically affected the mountain’s landscape. Kilimanjaro’s once-extensive glaciers have been receding at an alarming rate due to global warming.
Glacial Retreat
Experts estimate that Kilimanjaro’s glaciers could disappear entirely within the next few decades if current trends continue. While this is not related to volcanic activity, it serves as a reminder of how dynamic the mountain’s environment is.

When Was Mount Kilimanjaro Last Eruption : Interesting Facts About Kilimanjaro’s Volcanic Past
- Oldest Volcanic Cone: Shira is the oldest cone on Kilimanjaro, estimated to have formed around 2.5 million years ago. Today, it is mostly eroded, forming the Shira Plateau.
- Youngest Cone: Kibo, the highest peak, is the youngest of the three cones and the only one that could potentially erupt in the distant future.
- Ash Pit: Located inside the Reusch Crater, the ash pit is an iconic symbol of Kilimanjaro’s volcanic origins, with a depth of 120 meters (394 feet).
