When did Kilimanjaro first erupt?

About 750,000 years agoAbout 750,000 years ago, lava burst through cracks in the Earth's crust created by the shifting tectonic plates. The pressure of the erupting lava pushed the earth upwards, resulting in the Shira portion of Kilimanjaro forming. Shira was volcanically active for about 250,000 years before it collapsed to form a caldera.

How many volcanoes are there in Mount Kilimanjaro?

The three volcanoes of Mount Kilimanjaro started forming during the creation of the Greater Rift Valley. The three volcanoes continued to form over the next two and a half million years, as eruptions led to Mount Kilimanjaro as we see it today.

What was the name of the mountain that was born as the land began to shift?

As the land began to shift and the Greater Rift Valley began to form, Mount Kilimanjaro was born. You see, as some of the Earth began to fall and depress into the valley, other bits shot upwards forming volcanoes.

When did Shira collapse?

The first of these volcanoes to form, Shira would eventually collapse around a half million years ago, giving rise to Mawenzi nearly forty thousand years later. Kibo would form following later eruptions and is now the highest peak on the mountain.

How was Mount Kilimanjaro Formed?

Mount Kilimanjaro’s remarkable geological composition is the result of its volcanic origins. Kilimanjaro sits at the southern portion of the East African Rift system. This system is where some of the Earth’s tectonic plates meet together, and new plates are being formed while old plates are pulling away from each other and creating rifts.

What Sort of Rock is Mount Kilimanjaro Made Of?

Due to its volcanic origins, Mount Kilimanjaro is comprised of rock, lava, and ash. This volcanic activity also resulted in the majority of Kilimanjaro’s rocks being mostly composed of silicon dioxide. A large portion of the peak is comprised of andesites. Andesite is formed from volcanic activity and it has a variable color but tends to be grey or blue-grey.

What is the Great Rift Valley and What is Its Geology?

This rift system is a unique geological wonder. It is a series of rifts covering the Eastern edge of Africa, stretching through Ethiopia, Kenya, Uganda, and Tanzania. These rifts are present because it is here that the Earth’s tectonic plates are pulling away from each other while a new plate is being formed. Studying this area gives insight into how continents break apart.

What is a Stratovolcano?

Mount Kilimanjaro is considered a stratovolcano, but what exactly does that mean? A stratovolcano, also called a composite volcano, is a type of volcano that has andesite and dacite forms of lava, which tend to be thicker types of lava and cause pressure to build up until the volcano has an explosive eruption.

What are the Main Lava Formations of Kibo?

On Mount Kilimanjaro, Kibo is believed to have five main lava formations which created the towering mountain that stands today. The lava erupted from the Earth’s crust and then cooled as rock to form the bulk of the mountain. The volcanic phases of Mount Kilimanjaro started about 2.5 million years ago, at Shira. About 1 million years ago, the volcanic activity migrated east to Mawenzi and Kibo.

How the geology of Kilimanjaro has influenced its appearance?

Kilimanjaro is not only the highest mountain in Africa, it’s also one of the biggest volcanoes on Earth, covering an area of approximately 388,500 hectares.

How did Mawenzi form?

Soon after Shira’s extinction, Mawenzi started to form following a further eruption within the Shira caldera. Though much eroded, Mawenzi has at least kept some of its volcanic shape to this day. Then, 460,000 years ago, an enormous eruption just west of Mawenzi caused the formation of Kibo. Continual subterranean pressure forced Kibo to erupt several times more, forcing the summit ever higher until reaching a maximum height of about 5900m. A further huge eruption from Kibo 100,000 years later led to the formation of Kilimanjaro’s characteristic shiny black stone – which in reality is just solidified black lava, or obsidian. This spilled over from Kibo’s crater into the Shira caldera and around to the base of the Mawenzi peak, forming the so-called Saddle. Later eruptions created a series of distinctive mini-cones, or parasitic craters, that run in a chain south-east and north-west across the mountain, as well as the smaller Reusch Crater inside the main Kibo summit. The last volcanic activity of note, just over 200 years ago, left a symmetrical inverted cone of ash in the Reusch Crater, known as the Ash Pit, that can still be seen today.

What does Mawenzi look like?

Seen from Kibo, Mawenzi looks less like a crater than a single lump of jagged, craggy rock emerging from the Saddle (see ‘Other features of Kilimanjaro’ below). This is merely because its western side also happens to be its highest, and hides everything behind it.

How long ago did the eruption of Kibo occur?

Then, 460,000 years ago, an enormous eruption just west of Mawenzi caused the formation of Kibo. Continual subterranean pressure forced Kibo to erupt several times more, forcing the summit ever higher until reaching a maximum height of about 5900m.

What volcano erupted in Kilimanjaro?

The huge pressures behind this eruption pushed part of the Earth’s crust skywards, creating the Shira volcano, the oldest of the volcanoes forming the Kilimanjaro massif. Shira eventually ceased erupting around 500,000 years ago, collapsing as it did so to form a huge caldera (the deep cauldron-like cavity on the summit of a volcano) many times the size of its original crater.

What is the highest point on Kilimanjaro?

The Kibo summit is the best preserved crater on the mountain; its southern lip is slightly higher than the rest of the rim, and the highest point on this southern lip is known as Uhuru Peak. At 5895m, this is highest point in Africa and the goal of just about every Kilimanjaro trekker.

How deep is the Ash Pit in Kilimanjaro?

Within the inner Reusch Crater (1.3km in diameter) one can still see signs of volcanic activity, including fumaroles, the smell of sulphur and a third crater, the Ash Pit, 130m deep by 140m wide. The outer, Kibo Crater (1.9 by 2.7km), is not a perfect, unbroken ring.

Climate

The climate of Kilimanjaro is influenced by the height of the mountain, which allows the simultaneous influence of the equatorial trade winds and the high altitude anti-trades, and by the isolated position of the mountain. Kilimanjaro has daily upslope and nightly downslope winds, a regimen stronger on the southern than the northern side of the mountain. The flatter southern flanks are more extended and affect the atmosphere more strongly.
