Mount Cameroon: A Comprehensive Overview

Nov 06, 2025 0

Mount Cameroon, also known as Cameroon Mountain or Fako, is an active volcano situated in the Southwest Region of Cameroon, near the city of Buea and the Gulf of Guinea. Locally, it is known as Mongo ma Ndemi ("Mountain of Greatness").

The mountain is part of the Cameroon Volcanic Line, an area of volcanic activity that also includes Lake Nyos, the site of a significant disaster in 1986.

The Cameroon Volcanic Line

Mount Cameroon rises above the coast of west Cameroon. It overlooks the Bight of Biafra, part of the Gulf of Guinea. The dominantly basaltic-to-trachybasaltic edifice forms a volcanic horst constructed above a basement of Precambrian metamorphic rocks covered with Cretaceous to Quaternary sediments.

More than 100 small cinder cones, often fissure-controlled parallel to the long axis of the 1,400 km3 edifice, occur on the flanks and surrounding lowlands. A large satellitic peak, Etinde (also known as Little Cameroon), is located on the S flank near the coast.

Geographical and Historical Context

Mount Cameroon extends 14 miles (23 km) inland from the Gulf of Guinea, rising to a height of 13,435 feet (4,095 meters). It is the highest peak in sub-Saharan western and central Africa and the westernmost extension of a series of hills and mountains that form a natural boundary between northern Cameroon and Nigeria.

Sir Richard Burton climbed its summit in 1861. The town of Buea lies on the southeastern slope of the mountain, and the port of Limbe (formerly Victoria) lies at its southern foot.

The side of the mountain facing the sea has a mean annual precipitation level of more than 400 inches (10,000 mm) and is one of the wettest places in the world. The mountain’s rich volcanic soils support bananas, rubber, oil palms, tea, and cacao; valleys are used as pasture.

Impact of Eruptions

The eruption of 28 April-June 1909 caused the German colonial government of Kamerun to temporarily move from Buea to Douala.

Ecological Diversity

The mountain's natural vegetation varies with elevation.

Lowland forests: These are part of the Cross-Sanaga-Bioko coastal forests ecoregion and feature evergreen trees with a dense canopy 25 to 30 metres (80 to 100 ft) high. Taller emergent trees rise above the canopy, and many trees have buttress roots. The forests are diverse and species-rich, with numerous lianas.
Lower montane forests: Composed of evergreen trees forming a 20-25-metre-high (65-80 ft) canopy, these forests are either closed or discontinuous. Scattered areas of meadow and scrubland with grasses, herbs, tall herbaceous plants, tree ferns, woody shrubs, and low trees are also present. Frequent clouds and mists sustain profuse epiphytes, including mosses, ferns, and orchids. These forests are diverse and species-rich, with characteristic Afromontane plants and endemic species. Impatiens etindensis and I. grandisepala are herbaceous epiphytes endemic to the montane forests of Mount Cameroon.
Upper montane forest: Growing from 1,600-1,800 metres (5,200-5,900 ft) elevation, trees up to 20 metres (65 ft) high form an open-canopied forest with numerous epiphytes.
Montane scrub: Found between 1,800 and 2,400 metres (5,900 and 7,900 ft) elevation.
Montane grassland: Occurs between 2,000 and 3,000 metres (6,600 and 9,800 ft) elevation.
Sub-alpine grassland: Found at the highest elevations, from 3,000 metres (9,800 ft) to over 4,000 metres (13,000 ft).

Large mammals on the mountain include the African forest elephant (Loxodonta cyclotis), with a population of over 100 individuals. Other herbivores include red river hog (Potamochoerus porcus), bushbuck (Tragelaphus scriptus), bay duiker (Cephalophus dorsalis), blue duiker (Philantomba monticola), and yellow-backed duiker (Cephalophus sylvicultor).

Mount Cameroon and Bioko montane forests

The Mount Cameroon and Bioko montane forests is a tropical moist broadleaf forest ecoregion in central Africa. The montane forests occur as low as 500 meters elevation on Mount Cameroon.

Both Bioko and Mount Cameroon are part of the Cameroon Volcanic Line, a line of volcanoes that runs northeast-southwest across the Cameroon Highlands and extending into the Atlantic Ocean as the islands of Bioko, São Tomé, Príncipe, and Annobón. The montane forests of Mount Cameroon and Bioko are home to the distinct Afromontane flora of Africa's high mountains. The chief plant communities are montane forests, montane grasslands, and heathlands.

370 species of birds have been recorded on Mount Cameroon, including some endemics.

A 2017 assessment found that 736 km², or 64%, of the ecoregion is in protected areas.

Mount Cameroon National Park

Mount Cameroon National Park (Parc National du Mont Cameroun) was created in 2009. The International Union of Geological Sciences (IUGS) included 'The Quaternary Cameroon Volcano' in its assemblage of 100 'geological heritage sites' around the world in a listing published in October 2022.

Volcanic Activity

Mount Cameroon is one of Africa's largest volcanoes. More than 100 small cinder cones occur on its flanks and surrounding lowlands. Historical activity, the most frequent of West African volcanoes, was first observed in the 5th century BC.

Here's a chronological overview of some significant seismic and volcanic events:

February-March 1959: An eruption produced a large E-flank lava flow.
November 1975: Increased seismicity was recorded, but no eruption occurred.
October-November 1982: Lava fountaining from a radial fissure 6.5 km SW of the summit and a lava flow moved 12 km down the SW flank. Two towns were evacuated, and tephra caused damage to plantations.
1989: A minor explosive eruption formed a new crater at 2,860 m on the SW flank.
Early 1993: Local seismicity significantly increased.
March 1999: A volcanic eruption began on the S flank at about 2,650 m elevation. A second vent opened on 30 March at ~1,400 m elevation, sending a voluminous aa flow SSW through dense equatorial forest.
28 May and 20 July 2000: An eruption occurred. The seismic activity for this eruption lasted 3 months, up to September 2000.
3 February 2012: Mount Cameroon sent "ashes and flames" into the air in a brief explosion.

Seismic Activity Details:

Local seismicity at Mount Cameroon significantly increased in early 1993. Before then, an average of 10-12 events/month were recorded. The monthly number of seismic events increased to 20 in January-February 1993 and to 180 events in March. The number decreased in April, but rose to 130 in May. The frequency of earthquakes has steadily declined since then, but as of December 1993 had not returned to 1992 levels. Most of these events were centered on the SE flank of the volcano at depths of 30-60 km and had magnitudes of 1-3. This change in seismicity could be a long-range precursor to renewed volcanic activity.

Overall seismic activity was lower in 1994 (240 total events) compared to 1993 (840 events). Most of the 1993 activity was from beneath the SE flank. The monthly number of events was consistently below 30 after October 1993, until December 1994.

During 1996, the average rate of seismicity was 15 events/month, with the exception of January 1996, when a small outburst of 21 events was recorded. Magnitudes were always under 3.

Eruption of March 1999

On 26 March 1999, a volcanic eruption began on the S flank at about 2,650 m elevation. A second vent opened on the evening of 30 March at ~1,400 m elevation, and sent a voluminous aa flow SSW through dense equatorial forest toward the coastal village of Bakingili. By 31 March there were nine vents.

Twelve vents were located during an observation trip on 3 April. The vents were aligned along a pre-existing fracture zone bearing N40°E. The aa lava flows divided into various branches, the largest of which was 3 km long. The main hazards from this eruption were lava flows and volcanic ash, which was blown SW into villages along the coast.

Eruption of 2000

Wantim and others (2011) stated that the eruption occurred during 28 May and 20 July 2000. Eruptions at site 1 (~ 3,930 m a.s.l) began in the night of 28 May 2000 with an explosive phase that produced only tephra and ballistic blocks (Suh and others, 2003 and Wantim and others, 2011). A ~850 m-long ′a′a flow field was emplaced at this site a month later. The upper 2000 flow is one of the shortest (850 m) recorded for historical lava flows here despite having descended steep slopes. The lava flow field covers a total surface area of (8 ± 2) × 104 m2 with a total volume of (3.4 ± 0.8) × 105 m3.

Brief explosion--2012 news reports.

Cameroon state radio and television reports stated that Mount Cameroon sent "ashes and flames" into the air in a brief explosion on 3 February 2012.

Lava Flow Hazard and Risk

According to Favalli and others (2010), Mt. Cameroon is one of the most active effusive volcanoes in Africa. About 500,000 people living or working around its fertile flanks are subject to significant threat from lava flow inundation.

Simulated lava flows from about 80,000 possible vents were used to produce a detailed lava flow hazard map. Results show that the risk of lava flow inundation is greatest in the most inhabited coastal areas, specifically the town of Limbe. Buea, the second most important town in the area, has a much lower risk although it is significantly closer to the summit of the volcano. Non-negligible risk characterizes many villages and most roads in the area surrounding the volcano.

The details of the modeling and the resulting maps can be found in the cited references.

Seismic Activity (1993-1997)

The Mt. Cameroon region experienced an earthquake swarm during 1993. Since then, the frequency of seismic events in the region had remained low, with a mean of 15 earthquakes per month. On 26 March 1999, more than 15 seismic events were detected from the mountain.
