Thanks to everyone who attended and participated at TSG 2025, held at the British Geological Survey, Keyworth, you all helped to make it a great experience! We look forward to seeing you in Dublin in 2026!

Congratulations to our 2025 Prize winners:

Dave Johnston Mapping Prize Winner

Phoebe Stansfield

Project: Geomorphological evidence for post-glacial faulting in Sweden and South Greenland

Mike Coward Prize (best student presentation)

Mannon Carpenter

Presentation: Controls on Postseismic and Interseismic Deformation: Modelling Localised Rheological Weakening Beneath a Strike-Slip Fault

Manon is in her final year of PhD at the University of Leeds, where she combines field work, microstructural analyses and geophysical modelling to understand how and why deformation is localised in continental crust. She uses constraints from mid-crustal shear zones to inform numerical models of crustal-scale strike-slip faults and see what we can learn from them.

Natalie Forrest

Poster Title: Using Cosmogenic 36Cl To Estimate The Holocene Slip Rate of the Eşen Fault, SW Türkiye

Natalie is a 4th year PhD student at the University of Leeds, based in the Institute of Geophysics & Tectonics. Her PhD investigates the dynamics of normal faulting across multiple timescales, through a multi-disciplinary study involving geological and geodetic methods, such as InSAR and GPS. 

At the TSG AGM 2025, Natalie presented her laboratory-based study on cosmogenic chlorine-36 analysis on the Eşen Fault, a normal fault in SW Türkiye. There have been no known historical earthquakes on this fault, yet it is a prominent 20 km long escarpment across the landscape. Cosmogenic chlorine-36 is primary formed through the interaction of calcium-40 in the limestone with cosmic rays, therefore this method produces an estimate of the fault scarp exposure through time. By combining chlorine-36 profiles with Bayesian models, the study suggests that the fault scarp experienced its last large earthquake around 1000 years ago, and prior to that, the fault was slipping at 2-3 mm/yr. This shows that the fault represents a significant, and previously unquantified, hazard in this region.

Ramsay Medal Winner

Giovanni Toffol

Publication: On-fault earthquake energy density partitioning from shocked garnet in an exhumed seismic mid-crustal fault

Giovanni obtained a PhD at the University of Padova (Italy), with a thesis titled “High differential stress in the seismogenic lithosphere: constraints from numerical modelling and microstructural analysis”. He is currently postdoctoral research associate at Cardiff University, where his work focuses on the seismic and aseismic behaviour of faults in subduction zones.
