Specifically, it is a stratovolcano, also known as a composite volcano. A stratovolcano is a classic, cone-shaped type of volcano. It’s built from multiple layers of hardened lava, volcanic ash, and rock. Stratovolcanoes typically erupt explosively and grow tall and symmetrical.
Other famous examples include Mount Fuji in Japan and Mount Rainier in the United States.
Kilimanjaro was born from tectonic activity along the East African Rift. This massive fault system is slowly splitting the African continent. As the tectonic plates separated, magma from the mantle rose through the weakened crust.
Three Volcanic Cones

Mount Kilimanjaro isn’t just one volcano. It’s composed of three distinct volcanic cones:
Shira: The western cone. Formed about 750,000 years ago. Collapsed into a caldera, forming Shira Plateau. Extinct.
Mawenzi: A jagged peak on the east. Formed roughly 500,000 years ago. Extinct.
Kibo: The central and highest cone. Began erupting around 460,000 years ago. Dormant.
Kibo holds Kilimanjaro’s summit, Uhuru Peak (19,341 feet/5,895 meters). It went through five main lava-forming stages. The oldest is the Lava Tower group, visible at 15,000 feet (4,600 meters). Over time, successive eruptions built up dense formations that helped Kibo retain its height and shape, unlike the more heavily worn Shira and Mawenzi.
Kibo features a large crater and remnants of glacial ice.
What Is Kilimanjaro Made Of?
Kilimanjaro is primarily composed of volcanic rock:
Basalt: Dark, iron-rich lava that forms the mountain’s bulk. Basalt is heavy, hard, and common in oceanic and rift zone volcanoes.
Andesite: A lighter-colored volcanic rock formed from more viscous lava.
Obsidian: Natural volcanic glass created when lava cools rapidly.
Phonolite and tephriphonolite: Rare volcanic rocks found in the higher formations of Kibo.
The mix of materials gives Kilimanjaro its distinct coloration, steep structure, and durability.
Is Kilimanjaro Still Active?
Kibo is considered dormant. Its last major eruption was around 360,000 years ago. But volcanic activity may have occurred as recently as 10,000 years ago. It very well may erupt again.
Geothermal activity is still present in the form of hot gas vents near the crater. Scientists continue to monitor the volcano, though there is no sign of imminent eruption.
Shira and Mawenzi, on the other hand, are extinct. Their magma chambers have cooled and solidified.
In consideration of the services provided by Ultimate Kilimanjaro®, its shareholders, directors, officers, employees, agents, volunteers, participants and all other persons or entities associated with or acting in any capacity on its behalf (collectively referred to as “Ultimate Kilimanjaro®”), I hereby agree to release, indemnify, and discharge Ultimate Kilimanjaro®, on behalf of myself, my heirs, personal representative and estate and for all members of my family, including minor children, as follows:
1. I am aware that, during the trip or activity, I may be subjecting myself to dangers and hazards that could result in physical or emotional trauma, illness, injury, paralysis, death, or damage to myself, property, and/or third parties. I acknowledge that high-altitude mountain hiking entails known and unanticipated risks, including but not limited to: hazards of traveling in uneven mountainous terrain; slips and falls; being struck by rockfall, icefall, or other objects dislodged or thrown from above; forces of nature, including lightning and weather changes; the risk of falling from rocks or mountainsides; exposure to insect bites or animal attacks; altitude- and cold-related conditions including hypothermia, frostbite, acute mountain sickness, high-altitude cerebral edema, and high-altitude pulmonary edema; my own physical condition; and the physical exertion associated with this activity. Additional dangers may include travel in remote areas with limited infrastructure and medical services; risks associated with viewing wild animals; accidents or illness in remote places without access to emergency medical facilities; war; terrorism; and other disruptive forces. I understand that this description of risks is not complete and that other unanticipated inherent risks may occur. I recognize that such risks, dangers, and hazards may be present at any time during the trip. I also acknowledge that medical services or facilities may not be readily available or accessible during some or all of the time in which I am participating in the trip.

I further waive my right to a trial by jury in any such action.
6. I certify that I am physically and medically fit to participate on this trip. I understand that my resting pulse rate must be below 100 before beginning the trek. My pulse will be checked prior to departure, and if it exceeds 100, I will be required to obtain additional medical clearance before being permitted to start the trek. I acknowledge that failure to provide such clearance will result in denial of participation without refund.
7. I agree to obtain and maintain the required travel insurance to cover any injury, illness, or damage I may cause or suffer while participating in this trip. I agree to be fully responsible for all costs arising from such injury, illness, or damage. I further acknowledge and accept the risks associated with any medical or physical conditions I may have.
8. I understand that Ultimate Kilimanjaro® contracts with independent contractors to provide services on the trip or activity, including transportation, accommodations, and guiding. I acknowledge that Ultimate Kilimanjaro® has no control over, and accepts no responsibility for, the acts, omissions, or defaults of any contractor involved in providing such services. Ultimate Kilimanjaro® shall not be liable for any injury, damage, loss, delay, or irregularity arising from any cause, including but not limited to: vehicle defects; the acts or defaults of carriers or service providers; acts of God; detention, quarantine, or government restrictions; terrorism, war, strikes, or civil disturbances; theft; force majeure; accidents involving aircraft, boats, bicycles, motor vehicles, or other transport; or failures, delays, or changes in transit, accommodations, restaurants, or camping services.
By agreeing to this document, I acknowledge that I may be found by a court of law to have waived my right to maintain a lawsuit against Ultimate Kilimanjaro® for any claim released herein.
