Africa is being split apart by intense ‘superplume' of hot rock 1,800 miles below Earth's surface, experts warn
AFRICA is splitting apart - meaning the continent will form two separate land masses with an ocean in between in several million years, experts say.
But the driving force behind the continental drift has long been debated.

A gigantic superplume of hot rock, roughly 1,800 miles (2,900km) beneath the Earth's surface, is pushing up against the African crust and fracturing it.
Professor Fin Stuart, of the University of Glasgow and the Scottish Universities Environmental Research Centre (SUERC), led the project.

He said: "We have long been interested in how the deep Earth rises to surface, how much is transported, and just what role it plays on forming the large-scale topography of the Earth's surface.
"Our research suggests that a giant hot blob of rock from the core-mantle boundary is present beneath East Africa, it is driving the plates apart and propping up the Africa continent so it hundreds of metres higher than normal."
Experts suspected as much back in 2023, but geologists have now detected volcanic gases that back up the theory.
The Meengai geothermal field in central Kenya has a chemical signature that comes from deep inside Earth's mantle, matching those found in volcanic rocks to the north, in the Red Sea, and to the south, in Malawi.

The discovery indicates that all these locations are sat atop the same deep mantle rock, according to experts.

Study co-author, Biying Chen, of the University of Edinburgh and SUERC, said: "These gases from our geothermal wells have provide valuable new insight into the Earth's deep interior."
Chen added that the findings will help researchers to understand both the geological forces shaping East Africa and "the fundamental processes which drive the formation of our planet's surface over millions of years".

The East African Rift System (EARS) is the largest active continental rift system on Earth.
It is in the process of ripping through around 2,175miles (3,500km) of Africa.
Continental rifting is nothing new for Earth - and is the reason why we have seven continents today.
Roughly 240 million years ago, long before humans roamed, Earth was home to just one supercontinent known as Pangaea.

The Scottish Highlands, the Appalachians, and the Atlas Mountains were actually all part of the same mountain range on Pangaea, but were torn apart by continental drift.

Mysterious deep Earth ‘heartbeat' pulsing beneath Africa will form NEW ocean as it splits continent in two
A NEW ocean is forming beneath Ethiopia as a "heartbeat"-like pulse deep below the Earth's surface splits the African continent in two, according to scientists. While a new ocean will eventually give six countries a new coastline, neither you nor I will ever be able to swim in its waters. 5 The East African Rift System drives volcanic activity in places like the Erta Ale volcano in Ethiopia Credit: Getty 5 An international research team, led by Earth scientists at the University of Southampton, have discovered rhythmic surges of molten mantle rock rising from deep within the Earth. It is bubbling up beneath Africa - and its pulses are gradually tearing the continent apart, starting in the Afar region of Ethiopia. The Afar region is a rare place on Earth where three tectonic rifts converge: the Main Ethiopian Rift, the Red Sea Rift, and the Gulf of Aden Rift. Scientists previously thought Africa's tectonic plates, which collided to form large mountains and pulled apart to create vast basins millions of years ago, were simply moving apart again. READ MORE ON EARTH SCIENCE However, a in May suggested that intense volcanic activity deep underground Little was known about the hot upwelling of mantle and how it behaves beneath rifting tectonic plates - until now. The latest research, published in Nature Geoscience today, revealed that the giant fiery plume pulses like a "heartbeat" and is repeatedly pushing against the tectonic plate above it. When the tectonic plate eventually ruptures from the pressure, the continent will divide and a new ocean will flood in. Most read in Science "We found that the mantle beneath Afar is not uniform or stationary – it pulses, and these pulses carry distinct chemical signatures," lead author Dr Emma Watts, who conducted the research at the University of Southampton, said in a statement. Watts, who is now based at Swansea University, added: "These ascending pulses of partially molten mantle are channelled by the rifting plates above. Shocking moment 1,000ft fiery lava jet erupts in 6-hour volcano frenzy as scientists warn of wind spreading toxic gas "That's important for how we think about the interaction between Earth's interior and its surface." The team collected over 130 volcanic rock samples from across the Afar region and the Main Ethiopian Rift to piece together the structure of the deep Earth that is splitting. These pulses appear to behave differently depending on the thickness of the plate, and how fast it's pulling apart. Professor Tom Gernon, a co-author of the study Researchers found that the pattern of the rhythmic pulse is dictated by the tectonic plate it bubbles beneath - such as how the plate moves, or how thick it is. Professor Tom Gernon, a co-author of the study, said: "The chemical striping suggests the plume is pulsing, like a heartbeat. "These pulses appear to behave differently depending on the thickness of the plate, and how fast it's pulling apart. "In faster-spreading rifts like the Red Sea, the pulses travel more efficiently and regularly like a pulse through a narrow artery." 5 Women work on their farm near a chasm suspected to have been caused by a heavy downpour along an underground fault-line near the Rift Valley town of Mai Mahiu, Kenya in 2018 Credit: Reuters / Thomas Mukoya Associate professor Dr Derek Keir, another co-author of the study, said the findings had "profound implications" for how scientists understand volcanoes, earthquake activity, and the process of continental breakup. 'The work shows that deep mantle upwellings can flow beneath the base of tectonic plates and help to focus volcanic activity to where the tectonic plate is thinnest," he added.

German authorities confirm case of African swine fever in wild boar
Authorities in Germany have confirmed a case of African swine fever (ASF) in a wild boar in the state of North Rhine-Westphalia, in the northwest of the country. The presence of the disease was confirmed by the National Reference Laboratory for ASF at the Friedrich Loeffler Institute (FLI), the leading animal disease research centre in Germany. The dead boar was found in the district of Olpe, and further suspected cases are currently being clarified, the FLI said. The exact ASF virus type is also in the process of being confirmed at the FLI in order to support the outbreak investigation in addition to the epidemiological task force. The authorities in North-Rhine Westphalia immediately initiated protective and control measures, including the search for further dead wild boars. In Germany, the federal states are responsible for combating animal diseases. The authorities responsible under state law carry out the measures to control animal diseases, while the FLI supports the epidemiological investigations. The authorities cannot confirm at present if this case in a wild boar is linked with African swine fever outbreaks in several other German states. This can only be assessed by closer examination of the virus from the Olpe area. The FLI said that outbreak investigations are important in order to asses the extent of the epidemic and to be able to take appropriate control measures. Farmers in the area are being advised to review biosecurity measures. In the case of epidemics in Germany, cases have so far occurred in domestic pigs, especially is summer. Therefore, increased vigilance is required, the FLI said. In Ireland, the Department of Agriculture, Food and the Marine recently issued a reminder, via social media, for people never to feed food waste to pigs, as this can be a cause of ASF. In a post on social media platform X, the department said: 'African swine fever can survive for months to years in pork and pork products like cured hams, salamis, frozen pork, etc. Food waste containing infected meat that is eaten by animals can cause a disease outbreak. 'Never feed food waste to pigs,' the department post added.

He says: 'With global travel and population movement, there's every chance the disease could spread to new regions — if that happens in Europe, the consequences could be serious. Malaria No More UK's campaign film featuring David Beckham 'People who haven't been regularly exposed to malaria, like those in Europe, don't have the same immunity as those in Africa who have lived with the disease for some time, so the risk of severe illness or death is much higher.'

When an infected mosquito bites a person, the parasite enters the bloodstream and infiltrates red blood cells. Genetically engineered mosquitoes The Plasmodium parasite is adept at evading the immune system. It means a vaccine, which seems like the simplest option, is far from straightforward. So scientists are working on other cutting-edge solutions. Advertisement A team from Imperial College London , in partnership with a team at Ifakara, has genetically engineered mosquitoes resistant to the malaria parasite. It's hoped these mozzies will be released into the wild within eight years, dominating and repopulating areas within a few months. 'This is the first malaria-fighting technology that doesn't rely on human behaviour,' Dr Lwetoijera explains. 'With our current tools, like bed nets and insecticides, the biggest challenge is compliance. 'People have to use them consistently for them to work, which isn't always possible.' Funding is one of the biggest challenges scientists face. Advertisement And a huge blow came earlier this year when Donald Trump made abrupt cuts to foreign aid, and Keir Starmer announced plans to slash the overseas aid budget to its lowest level in a generation. Dr Sarah Moore, who has worked at Ifakara for 20 years, says: 'Every day, the equivalent of four jumbo jets full of children die of malaria in Africa. 'If aid continues to fall as predicted, it could rise to five. Because it's Africa, no one cares.' Among other developments, drones are being used to find and dismantle mosquito breeding grounds in Dar es Salaam, such as stagnant water pools, leafy foliage and shaded areas.

As Alex Limwagu, a research scientist, sets mosquito traps in the garden, Mwanabibi tells me her children have caught the disease more times than she can count — the family can't afford nets — but it never quells her panic. 'I rush straight to the hospital because I know in two minutes they could die,' she says. Advertisement Since the mosquito team arrived this year, Mwanabibi has learned more about protecting her family. 'I used to be ignorant,' she says. 'But Alex taught me how mosquitoes breed and how to protect my children. If malaria disappeared, life would be peaceful.' The WHO wants to reduce global malaria by 90 per cent by 2030. It believes the ambitious target is 'achievable' — but not without the dedicated scientists on the ground and the funds to keep them going.
