69-397: The river is approximately 200 km long. It flows into Lake Malawi . It originates from Dzalanyama Forest Reserve on the border between districts of Lilongwe and Dedza . Lilongwe river is the main source of water for Lilongwe city residents. 13°47′S 34°25′E  /  13.783°S 34.417°E  / -13.783; 34.417 This article related to

138-414: A feedback with one another, controlled by oblique rifting conditions. According to this theory, lithospheric thinning generates volcanic activity, further increasing magmatic processes such as intrusions and numerous small plumes. These processes further thin the lithosphere in saturated areas, making the thinning lithosphere behave like a mid-ocean ridge . According to marine geologist Kathleen Crane ,

207-417: A few hundred metres long. 1. Diplotaxodon , one of the very few cichlid genera that occurs offshore in relatively deep water. 2. Nimbochromis livingstonii is a piscivorous hap that is famous for playing dead to lure prey close. 3. As typical of utaka , Copadichromis azureus has bright blue males (shown) and duller females that are silvery with dark spots. 4. Aulonocara stuartgranti

276-585: A few hundred years ago. The Malawi haplochromines are mouthbrooders , but otherwise vary extensively in general behaviour and ecology. Within the Malawi haplochromines there are two main groups, the haps and the mbuna . The haps (they were formerly included in Haplochromis ) can be further subdivided into three subgroups: The relatively large, often more than 20 cm (8 in) long, and aggressive piscivores that roam various habitats in pursuit of prey,

345-527: A head in 1967 when Tanzania officially protested to Malawi; however nothing was settled. Occasional flare-ups of conflict occurred during the 1990s and in the 21st century. In 2012, Malawi's oil exploration initiative brought the issue to the fore, with Tanzania demanding that exploration cease until the dispute was settled. In 1954, an agreement was signed between the British and the Portuguese making

414-625: A larger Great Rift Valley that extended north to Asia Minor . A narrow zone, the rift is a developing divergent tectonic plate boundary where the African plate is in the process of splitting into two tectonic plates, called the Somali plate and the Nubian plate , at a rate of 6–7 mm (0.24–0.28 in) per year. The rift system consists of three microplates, the Victoria microplate to

483-654: A manner comparable to the egg-spots on the anal fin of haplochromines. The vast majority of the fish species in the lake are cichlids. Among the non-cichlid native fish are several species of cyprinids (in genera Barbus , Labeo and Opsaridium , and the Lake Malawi sardine Engraulicypris sardella ), airbreathing catfish ( Bathyclarias and Clarias , and the kampango Bagrus meridionalis ), mochokid catfish ( Chiloglanis and Malawi squeaker Synodontis njassae ), Mastacembelus spiny eel, mormyrids ( Marcusenius , Mormyrops and Petrocephalus ),

552-649: A number of active and dormant volcanoes, among them: Mount Kilimanjaro , Mount Kenya , Mount Longonot , Menengai Crater, Mount Karisimbi , Mount Nyiragongo , Mount Meru and Mount Elgon , as well as the Crater Highlands in Tanzania. Although most of these mountains lie outside of the rift valley, the EAR created them. Notable active examples of EAR volcanism include Erta Ale , Dalaffilla (also called Gabuli, Alu-Dalafilla), and Ol Doinyo Lengai . Erta Ale

621-401: A pre-Cambrian weakness in the crust, a suture zone of multiple cratons , displacement along large boundary faults, and the development of deep asymmetric basins. The second stage of rifting was characterized by the deactivation of large boundary faults, the development of internal fault segments, and the concentration of magmatic activity towards the rifts. Today, the narrow rift segments of

690-584: A river in Malawi is a stub . You can help Misplaced Pages by expanding it . Lake Malawi Lake Malawi , also known as Lake Nyasa in Tanzania and Lago Niassa in Mozambique , ( Swahili : Ziwa Nyasa ) is an African Great Lake and the southernmost lake in the East African Rift system, located between Malawi , Mozambique and Tanzania. It is the fourth largest freshwater lake in

759-447: A total surface area of about 29,600 square kilometres (11,400 sq mi). The lake is 706 m (2,316 ft) at its deepest point , located in a major depression in the north-central part. Another smaller depression in the far north reaches a depth of 528 m (1,732 ft). The southern half of the lake is shallower; less than 400 m (1,300 ft) in the south-central part and less than 200 m (660 ft) in

828-469: A west-facing scarp (east-plunging arch) along the southern half of its length that rises to 2,300 m (7,500 ft) above the sea floor. Its movement is concurrent with the EAR. Over time, many theories have tried to clarify the evolution of the East African Rift. In 1972 it was proposed that the EAR was not caused by tectonic activity, but rather by differences in crustal density. Since

897-795: Is a basaltic shield volcano in the Afar Region of northeastern Ethiopia, active continuously since at least 1967, with a summit lava lake documented since at least 1906. The 2008 eruption of Dalafilla, its only documented activity since the start of the Holocene , is the largest recorded eruption in Ethiopian history. Ol Doinyo Lengai is currently the only active natrocarbonatite volcano on Earth. Its magma contains almost no silica; typical lava flows have viscosities of less than 100 Pa⋅s, comparable to olive oil at 26 °C (79 °F). EAR-related volcanic structures with dated activity since

966-447: Is a suitable tool to investigate Earth's subsurface structures deeper than the crust. It is an inverse problem technique that models which are the velocities of the inner Earth that reproduce the seismographic data recorded all around the world. Recent improvements of tomographic Earth models of P wave and S wave velocities suggest that a superplume upwelling from the lower mantle at the northeastern EAR feeds plumes of smaller scale into

1035-507: Is at a depth of approximately 250 m (820 ft), effectively restricting fish and other aerobic organisms to the upper part. The water is very clear for a lake and the visibility can be up to 20 m (66 ft), but slightly less than half this figure is more common and it is below 3 m (10 ft) in muddy bays. However, during the rainy season months of January to March, the waters are more muddy due to muddy river inflows. The Portuguese trader Candido José da Costa Cardoso

1104-495: Is being split into two pieces. This is called a divergent plate tectonics boundary. Malawi has typically been estimated to be 1–2 million years old (mya), but more recent evidence points to a considerably older lake with a basin that started to form about 8.6 mya and deep-water condition first appeared 4.5 mya. The water levels have varied dramatically over time, ranging from almost 600 m (2,000 ft) below current level to 10–20 m (33–66 ft) above. During periods

1173-523: Is generally cool and strong. Many cratons are found throughout the EAR, such as the Tanzania and Kaapvaal cratons . The cratons are thick, and have survived for billions of years with little tectonic activity. They are characterized by greenstone belts , tonalites , and other high-grade metamorphic lithologies. The cratons are of significant importance in terms of mineral resources , with major deposits of gold, antimony, iron, chromium and nickel. A large volume of continental flood basalts erupted during

1242-583: Is not found in the lake. Pelagic zooplanktonic species include two cladocerans ( Diaphanosoma excisum and Bosmina longirostris ), three copepods ( Tropodiaptomus cunningtoni , Thermocyclops neglectus and Mesocyclops aequatorialis ), and several ostracods (including both described and undescribed species ). Lake Malawi is famous for the huge swarms of tiny, harmless lake flies, Chaoborus edulis . These swarms, typically appearing far out over water, can be mistaken for plumes of smoke and were also noticed by David Livingstone when he visited

1311-570: Is part of a group of relatively peaceful species popularly known as peacock cichlids . 5. Fossorochromis rostratus is an "aberrant" hap that often sifts mouthfuls of sand to extract small food organisms. 6. Like many mbuna , Pseudotropheus saulosi is a small cichlid where both male (blue and black) and female (yellow) are colorful. Lake Malawi is noted for being the site of evolutionary radiations among several groups of animals, most notably cichlid fish. There are at least 700 cichlid species in Lake Malawi, with some estimating that

1380-504: The African tetra Brycinus imberi , the poeciliid Aplocheilichthys johnstoni , the spotted killifish ( Nothobranchius orthonotus ), and the mottled eel ( Anguilla nebulosa ). At a genus level, most of these are widespread in Africa, but Bathyclarias is entirely restricted to the lake. Lake Malawi is home to 28 species of freshwater snails (including 16 endemics) and 9 bivalves (2 endemics, Aspatharia subreniformis and

1449-677: The Albertine Rift , and farther south, the valley of Lake Malawi . The rift also continues offshore from the coast of Mozambique along the Kerimba and Lacerda grabens , which are joined by the Davie Ridge, a 2,200 km-long (1,400 mi) relic fracture zone that cuts across the West Somali basin, straddling the boundary between Tanzania and Mozambique. The Davie Ridge ranges between 30–120 km (19–75 mi) wide, with

1518-558: The Ethiopian Highlands and the Kenya Highlands are hotspots of higher rainfall amid the semi-arid to arid lowlands of East Africa. Lakes which form within the rift, including Lake Victoria , have a large effect on regional climate. They are a source of water vapour, and also lead to the formation of lake breeze systems , which affect weather across large areas of East Africa. The east to west river valleys within

1587-641: The Oligocene , with the majority of the volcanism coinciding with the opening of the Red Sea and the Gulf of Aden approximately 30 Ma. The composition of the volcanics are a continuum of ultra-alkaline to tholeiitic and felsic rocks. It has been suggested that the diversity of the compositions could be partially explained by different mantle source regions. The EAR also cuts through old sedimentary rocks deposited in ancient basins. The East African Rift Zone includes

1656-760: The increasing human population near the lake, but some are exported from Malawi. The wild population of fish is increasingly threatened by overfishing and water pollution . A drop in the lake's water level represents another threat, and is believed to be driven by water extraction by the increasing human population, climate change and deforestation . The chambo and kampango have been particularly overfished (the kampango declined by about 90% from 2006 to 2016, O. karongae and O. squamipinnis by about 94%, and O. lidole might already be extinct ) and they are now seriously threatened . The IUCN recognises 117 species of Malawi cichlids as threatened; some of these have tiny ranges and may be restricted to rocky coastlines only

1725-495: The unionid Nyassunio nyassaensis ). The endemic freshwater snails are all members of the genera Bellamya , Bulinus , Gabbiella , Lanistes and Melanoides . Lake Malawi is home to a total of four snail species in the genus Bulinus , which is a known intermediate host of bilharzia . A survey in Monkey Bay in 1964 found two endemic species of snails of the genus ( B. nyassanus and B. succinoides ) in

1794-482: The upper mantle . Parallel to geological and geophysical measures (e.g. isotope ratios and seismic velocities) it is constructive to test hypotheses on computer based geodynamical models. A 3D numerical geodynamic model of the plume-crust coupling was capable of reproducing the lateral asymmetry of the EAR around the Tanzania craton . Numerical modeling of plume-induced continental break-up shows two distinct stages, crustal rifting followed by lithospheric breakup, and

1863-459: The 1990s, evidence has been found in favor of mantle plumes beneath the EAR. Others proposed an African superplume causing mantle deformation. Although the effects of deep-rooted mantle plumes are an important hypothesis, their location and dynamics are poorly understood, and a matter of active research. The question is still debated. The most recent and accepted view is the theory put forth in 2009: that magmatism and plate tectonics have

1932-950: The Afar triple junction, the rift follows two paths: west to the Red Sea Rift and east to the Aden Ridge in the Gulf of Aden . Southward from the Afar triple junction , the EAR consists of two main branches. The Eastern Rift Valley (also known as Gregory Rift ) includes the Main Ethiopian Rift , runs southward from the Afar triple junction, and continues south as the Kenyan Rift Valley, then transects Congo DR , Uganda , Rwanda , Burundi , Zambia , Tanzania , Malawi and Mozambique . The Western Rift Valley includes

2001-472: The East African Rift system form zones of localized strain. These rifts are the result of the actions of numerous normal faults which are typical of all tectonic rift zones. As aforementioned, voluminous magmatism and continental flood basalts characterize some of the rift segments, while other segments, such as the Western branch, have only very small volumes of volcanic rock. The African continental crust

2070-589: The Malawi system, which also includes nearby smaller Lake Malombe and the upper Shire River. Many of these have become popular among aquarium owners due to their bright colors. Recreating a Lake Malawi biotope to host cichlids became quite popular in the aquarium hobby. Most Malawi cichlids are found in relatively shallow coastal waters, but Diplotaxodon has been recorded down to depths of 200–220 m (660–720 ft) and several (especially Diplotaxodon , Rhamphochromis and Copadichromis quadrimaculatus ) are known from pelagic waters. The cichlids of

2139-459: The Shire River are vital for the economy as the water resources support hydropower, irrigation and downstream biodiversity. Concerns have been raised over the future climate change impacts of Lake Malawi due to the recent decline in lake levels and the overall drying trend. The climate in the lake region is already experiencing changes, with the temperatures predicted to increase throughout

The Somali Jet supplies water vapour for the high rainfall during the Indian Monsoon and is responsible for roughly half the global cross-equatorial atmospheric mass flux in the lower-branch of Hadley Circulation . The Rift Valley in East Africa has been a rich source of hominid fossils that allow the study of human evolution. The rapidly eroding highlands quickly filled

2277-416: The actual figure is as high as 1,000 species. The actual number is labelled with some uncertainty because of the many undescribed species and the extreme variation among some species, making the task of delimiting them very complex. Except for four species ( Astatotilapia calliptera , Coptodon rendalli , Oreochromis shiranus and Serranochromis robustus ), all cichlids in the lake are endemic to

The larvae are an important food source for fish, and the adult flies are important both to birds and local people, who collect them to make kungu cakes/burgers, a local delicacy with a very high protein content. In January 2015, a sediment control tank collapsed at the Paladin Energy -owned uranium mine in Northern Malawi after a high intensity rain storm hit the area. It

The Malawi blue crab, Potamonautes lirrangensis ( syn. P. orbitospinus ), is the only crab in the lake and it is not endemic. The atyid shrimp Caridina malawensis is endemic to the lake, but it is poorly known and has historically been confused with C. nilotica , which

2484-522: The border. The wrangle in this dispute occurred when the British colonial government, just after they had captured Tanganyika from Germany, placed all of the waters of the lake under a single jurisdiction, that of the territory of Nyasaland , without a separate administration for the Tanganyikan portion of the surface. Later in colonial times, two jurisdictions were established. The dispute came to

2553-410: The country. The lake is about 350 kilometres (220 mi) southeast of Lake Tanganyika , another of the great lakes of the East African Rift. The Lake Malawi National Park is located at the southern end of the lake. Malawi is one of the major Rift Valley lakes and an ancient lake . The lake lies in a valley formed by the opening of the East African Rift , where the African tectonic plate

The largest river flowing into it is the Ruhuhu River , and there is an outlet at its southern end, the Shire River , a tributary that flows into the Zambezi River in Mozambique. Evaporation accounts for more than 80% of the water loss from the lake, considerably more than the outflowing Shire River. The outflows from Lake Malawi into

The EAR began developing around the onset of the Miocene , 22–25 million years ago. It was formerly considered to be part of

2760-499: The lake are divided into two groups and the vast majority of the species are haplochromines . The sister species to the Malawi haplochromines is Astatotilapia sp. Ruaha (a currently undescribed species from Great Ruaha River ), and these two separated between 2.13 and 6.76 million years ago (mya). The earliest divergence within the Malawi haplochromines occurred between 1.20 and 4.06 mya, but most radiations in this group are far younger; in extreme cases species may have diverged only

2829-493: The lake dried out almost completely, leaving only one or two relatively small, highly alkaline and saline lakes in what currently are Malawi's deepest parts. A water chemistry resembling the current conditions only appeared about 60,000 years ago. Major low-water periods are estimated to have occurred about 1.6 to 1.0–0.57 million years ago (where it might have dried out completely), 420,000 to 250,000–110,000 years ago, about 25,000 years ago and 18,000–10,700 years ago.

2898-535: The lake is included in Lake Malawi National Park . Lake Malawi is a meromictic lake , meaning that its water layers do not mix. The permanent stratification of Lake Malawi's water and the oxic- anoxic boundary are maintained by moderately small chemical and thermal gradients . Lake Malawi is between 560 kilometres (350 mi) and 580 kilometres (360 mi) long, and about 75 kilometres (47 mi) wide at its widest point. The lake has

2967-477: The lake's surface area between Malawi and Tanzania is under dispute. Tanzania claims that the international border runs through the middle of the lake. On the other hand, Malawi claims the whole of the surface of this lake that is not in Mozambique, including the waters that are next to the shoreline of Tanzania. Both sides cite the Heligoland Treaty of 1890 between Great Britain and Germany concerning

3036-498: The lake, and two non-endemic species ( B. globosus and B. forskalli ) in lagoons separated from it. The latter species are known intermediate hosts of bilharzia, and larvae of the parasite were detected in water containing these, but in experiments C. Wright of the British Museum of Natural History was unable to infect the two species endemic to the lake with the parasites. The field workers, who spent many hours on and in

3105-401: The lake, did not find either B. globosus or B. forskalli in the lake itself. More recently, the disease has become a problem in the lake itself as the endemic B. nyassanus has become an intermediate host. This change, first noticed in the mid-1980s, is possibly related to a decline in snail-eating cichlids (for example, Trematocranus placodon ) due to overfishing and/or a new strain of

3174-850: The lake, the Hermann von Wissmann , commanded by Captain Berndt. Rhoades's crew found the Hermann von Wissmann in a bay near Sphinxhaven , in German East African territorial waters. Gwendolen disabled the German boat with a single cannon shot from a range of about 1,800 metres (2,000 yd). This brief conflict was hailed by The Times in England as the British Empire's first naval victory of World War I. The partition of

3243-411: The lake. The aquatic larvae feed on zooplankton, spending the day at the bottom and the night in the upper water levels. When they pupate they float to the surface and transform into adult flies. The adults are very short-lived and the swarms, which can be several hundred metres tall and often have a spiraling shape, are part of their mating behaviour. They lay their eggs at the water's surface and

3312-520: The mbuna, a name used both locally and popularly, which means "rockfish" in Tonga . They are found at rocky outcrops, territorially aggressive (although commonly found in high densities) and often specialised aufwuchs feeders. The mbuna species tend to be relatively small, mostly less than 13 cm (5 in) long, and often both sexes are brightly colored with males having egg-shaped yellow spots on their anal fin (a feature particularly prevalent in

3381-468: The mbuna, but not exclusive to this group). The second group, the tilapia , comprises only six species in two genera in Lake Malawi: The redbreast tilapia ( Coptodon rendalli ), a widespread African species, is the only substrate-spawning cichlid in the lake. This large cichlid mainly feeds on macrophytes . The remaining are five mouthbrooding species of Oreochromis ; four chambo in

MV  Chauncy Maples began service on the lake in 1901 as the SS Chauncy Maples : a floating clinic and church for the Universities' Mission to Central Africa . She later served as a ferry and is currently being renovated into a mobile clinic at Monkey Bay . The renovation

3519-503: The most popular are the four species of chambo, consisting of any one of four species in the subgenus Nyasalapia ( Oreochromis karongae , O. lidole , O. saka and O. squamipinnis ), as well as the closely related O. shiranus . Other species that support important fisheries include the Lake Malawi sardine ( Engraulicypris sardella ) and the large kampango catfish ( Bagrus meridionalis ). Most fishing provides food for

3588-809: The north, and the Rovuma and Lwandle microplates to the south. The Victoria microplate is rotating anti-clockwise with respect to the African plate. Its rotation is caused by the configuration of mechanically weaker and stronger lithospheric regions in the EARS. Many of the African Great Lakes lie within the Rift Valley. A series of distinct rift basins, the East African Rift System extends over thousands of kilometers. North of

3657-671: The onset of the Holocene include approximately 50 in Ethiopia, 17 in Kenya , and 9 in Tanzania . The EAR is the largest seismically active rift system on Earth today. The majority of earthquakes occur near the Afar Depression, with the largest typically occurring along or near major border faults. Seismic events in the past century are estimated to have reached a maximum moment magnitude of 7.0. The seismicity trends parallel to

The lake's water is alkaline ( pH 7.7–8.6) and warm with a typical surface temperature between 24 and 29 °C (75–84 °F), while deep sections typically are about 22 °C (72 °F). The thermocline is located at a depth of 40–100 m (130–330 ft). The oxygen limit

3864-488: The rift could eventually cause eastern Africa to separate from the mainland, although this potential event could take tens of millions of years. Studies that contribute to the broader understanding on the evolution of rifts can be grouped into the techniques of isotope geochemistry, seismic tomography and geodynamical modeling. The varying geochemical signatures of a suite of Ethiopian lavas suggest multiple plume sources: at least one of deep mantle origin, and one from within

3933-691: The rift system, including the Turkana Channel in northern Kenya and the Zambezi river valley, concentrate low-level easterly winds and accelerate them towards Central Africa . This leaves East Africa drier than it otherwise would be, and also supports the high rainfall in the Congo Basin rainforest . The formation of the east–west valleys could in turn be important for the aridification of East Africa over millions of years. The barrier presented by EARS concentrates monsoonal winds (known as

4002-451: The rift system, with a shallow focal depth of 12–15 km (7.5–9.3 mi) beneath the rift axis. Further away from the rift axis, focal depths can be below 30 km (19 mi). Focal mechanism solutions strike NE and frequently demonstrate normal dip-slip faulting, although left-lateral motion is also observed. The East African Rift system affects regional, continental and even global climate. Regions of higher elevation, including

4071-411: The subcontinental lithosphere. In accordance, a 2014 study compares the geochemical signature of rare earth isotopes from xenoliths and lava samples collected in the EAR. The results corroborate the coexistence of a superplume "common to the entire rift" with another mantle material source being either of subcontinental type or of mid-ocean ridge type. The geophysical method of seismic tomography

4278-464: The upwelling between stages of an upper mantle plume. Prior to the rift's formation, enormous continental flood basalts erupted, uplifting the Ethiopian , Somali, and East African plateaus. The first stage of rifting of the EAR was characterized by rift localization and magmatism along the entire rift zone. Periods of extension alternated with relative inactivity. There was also the reactivation of

4347-455: The valley with sediments, creating a favorable environment for the preservation of remains. The bones of several hominid ancestors of modern humans have been found here, including those of " Lucy ", a partial australopithecine skeleton discovered by anthropologist Donald Johanson dating back over 3 million years. Richard and Mary Leakey have also done significant work in this region. In 2008, two other hominid ancestors were discovered here:

She normally serves the southern part of the lake but if Ilala was out of service she operated the route to Karonga. The Tanzanian ferry MV  Songea was built in 1988. Her operator was the Tanzania Railway Corporation Marine Division until 1997, when it became the Marine Services Company Limited . Songea plies weekly between Liuli and Nkhata Bay via Itungi and Mbamba Bay . The worst Lake disaster
