“The Kenyan Rift volcanoes are part of a larger Great Rift Valley complex that extends all the way from Mozambique to Djibouti; their presence in East Africa attests to the presence of magma reservoirs within the Earth’s crust,” said Lead Author Dr. Juliet Biggs, Rosenstiel Postdoctoral Fellow at the University of Miami. “Our study detected signs of activity in only four of the 11 volcanoes in the area -- Suswa, Menengai, Longonot and Paka -- all within the borders of Kenya.”
“The fact that these areas are so close to a major metropolitan area pose a challenge in terms of a large volcanic or seismic event” says co-author Cindy Ebinger. Suswa, Menengai and Longonot are all located in densely populated areas within 100 km of Nairoibi.
The study also provides insight as to the geothermal potential of the region. Kenya was the first African country to build geothermal energy plants to generate this renewable, environmentally friendly alternative to coal and oil. The impact of harnessing such a resource could provide an important economic engine for the region.
Geothermal energy is generated by drilling deep holes into the Earth’s crust, pumping cold water through one end so by the time it resurfaces it is steam, which is then used to fuel a turbine, which in turn drives a generator, and creates power.
“This study demonstrates the potential for using InSAR to measure active magmatic and tectonic phenomena in Africa, allowing us to watch the processes by which continents break apart” says lead author Juliet Biggs, who has just begun a 2-year project at the University of Oxford, funded by the European Space Agency, to map the pattern of volcanic activity, dike intrusion and active faulting along the whole of the East African Rift.

At the Hannover Messe 2018, the Bundesanstalt für Materialforschung und-prüfung (BAM) will show how, in the future, astronauts could produce their own tools or spare parts in zero gravity using 3D printing. This will reduce, weight and transport costs for space missions. Visitors can experience the innovative additive manufacturing process live at the fair.
Powder-based additive manufacturing in zero gravity is the name of the project in which a component is produced by applying metallic powder layers and then...
Physicists at the Laboratory for Attosecond Physics, which is jointly run by Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics, have developed a high-power laser system that generates ultrashort pulses of light covering a large share of the mid-infrared spectrum. The researchers envisage a wide range of applications for the technology – in the early diagnosis of cancer, for instance.
Molecules are the building blocks of life. Like all other organisms, we are made of them. They control our biorhythm, and they can also reflect our state of...
University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...
Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.
The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
