Dr Tim Craig

Profile

I completed my PhD at the Bullard Laboratories in University of Cambridge, on the topic of Constraining Lithosphere Rheology using Earthquake Seismology. This work focused on the separate projects: the seismicity and lithospheric structure of Africa (particularly along the East African Rift System), rare deep earthquakes beneath the Himalayas and the Tibetan Plateau and their relationship to the thermal evolution of India as it underthrusts Tibet, and the seismicity and deformation associated with the flexure of oceanic plates just prior to subduction, in outer rises.

Following this, I spent two years working as a postdoctoral researcher in the Laboratoire de Geologie at the Ecole Normale Supérieure in Paris on a number of topics related to continental deformation. These years were funded by a fellowship from ENS (Year 1) and through the French Investment Program SINAPS project (Year 2), supported by the Commissariat à l'Énergie Atomique and the Institute de Radioprotection et Sûreté Nucléaire. My time in Paris was spent investigating the cases of rare intraplate earthquakes in North America and Europe, the factors controlling their distribution in space and time, how these earthquakes relate to the concept of a 'seismic cycle' in plate interiors, and how they may reflect the interplay between tectonic and Earth-surface processes.

In late 2015 I joined the University of Leeds, working as an Independent Research Fellow at the University of Leeds, funded by the Royal Commission for the Exhibition of 1851, within the Institute of Geophysics and Tectonics. My work during this fellowship focused on multidisciplinary studies of earthquakes and tectonics, principally in intraplate settings. In November 2018, I became a Royal Society University Research Fellow, remaining at the University of Leeds.  This fellowship is focused on looking at the time-variable behaviour of fault systems, and the the seismicity associated with then, particularly as a result of shorter term (ie., human-observable) external processes, both those related to other tectonic processes, and those from non-tectonic sources. 

Currently, my work ranges from investigating the seismicity associated with deformation in shallow subducting slabs, to the interaction between tectonic and non-tectonic processes, and how this may impact on seismicity.

Research interests

I work on a range of problems relating to intraplate earthquakes and tectonics, using a combination of earthquake seismology, tectonic geodesy, and geodynamic modelling.
