GCG’s Tom Morgan will be giving a talk entitled “Faulting under London” to the London branch of the Open University’s Geological Society on the 28th April 2022 at 19:00. The event, which is open to all, will be in-person only at All Saints Margaret Street, 7 Margaret Street London W1W 8JG (nearest Tube Station Oxford Circus). Further details about the event can be found here.
Major faults in London’s near surface are becoming recognised as both a geological unknown and a geotechnical risk since their origins, extents and architectures are poorly constrained. Tom will provide an overview of key outputs from his PhD characterising major faulting in London where he proposed that Alpine-reactivated basement faults propagated into the cover to cause regionalised partitioning of the subsurface and the development of localised shear zones or ‘fault zones’. The outcome is a more structurally complex view of London that contains both faulting and folding (particularly in East London), and raises questions about the London Basin’s structure.
