By PhD students Aude Lavayssiere and Finn Illsley-Kemp. As part of the RiftVolc project aiming to understand magmatism and rifting in the East African Rift System, Dr Derek Keir and two PhD students, Finn Illsley-Kemp and Aude Lavayssiere, went to Ethiopia last month to deploy seismic stations. RiftVolc is a project that started in September… Read More Seismic deployment in the Main Ethiopian Rift
PhD students Ryan Gallacher and Finn Illsley-Kemp have recently completed a two week trip to Lake Tanganyika in Tanzania. They were performing a service run on the seismic network that was deployed earlier in the year. The project, “Active fault kinematics during non-volcanic rifting in East Africa”, is in collaboration with Beach Petroleum (Tanzania) Ltd., the… Read More G&G pgr students complete seismic service run at Lake Tanganyika, Tanzania
Dr. Derek Keir and PhD student Ryan Gallacher have recently completed a two and a half week seismic deployment around the South of Lake Tanganyika in Tanzania. This work was completed in collaboration with Beach Petroleum (Tanzania) Ltd. and the University of Rochester (USA) with the approval of the Tanzania Petroleum Development Corporation. The project… Read More Lake Tanganyika Seismic Deployment
Volcanoes commonly form on the flanks of young continental rifts, whereas in more evolved rifts the volcanism is more commonly in the rift centre. Derek Keir, Lecturer in Earth Science from the Geology and Geophysics research Group, contributed to a team that modelled the stress field below rift grabens of varying width and depth caused… Read More Off-rift volcanism in rift zones determined by crustal unloading, new paper in nature Geoscience
A workshop on the structure and dynamics of the lithosphere-asthenosphere system was organized at the College de France, Paris, from 19-20 November 2013. The primary focus of the workshop was to enhance understanding of the dynamics interaction between the colder, more brittle lithosphere and the warmer, more ductile asthenosphere by combining constraints from observations and… Read More Understanding the structure and dynamics of the lithosphere-asthenosphere system
The highlight of this year’s British Geophysical Association (BGA) Postgraduate Research in Progress meeting, hosted by the University of Cambridge, was undoubtedly the annual Bullerwell Lecture. The 2013 Bullerwell Lectureship (presented each year by the Royal Astronomical Society to ‘an outstanding, young British Geophysicist’) was awarded to Dr. Derek Keir, lecturer in Earth Science at the… Read More Bullerwell Lecture 2013 – Magmatism and deformation during continental breakup
A recent paper in Nature, Dr Derek Keir, from Geology and Geophysics research group at Ocean and Earth Science, has recently been involved in a study on the Afar Rift Valley. The Nature paper by Ferguson and coauthors used geochemical data from lavas erupted along the the Afar rift valley to constrain the origin of magmatism… Read More Hot and Deep: Melting during late-stage rifting in Afar
