Research Summary

The UCL-IRDR promotes doing scientific research that can influence disaster risk reduction practice within academia, industry, NGOs and government. 

Faure Walker's main research interests include earthquake geology and seismic hazard. Her principal publications focus on the importance of fault geometry and rates of motion in understanding fault interactions, fault growth and the dynamic forces controlling these.
 
Joanna's research has provided new insights into regional mechanisms of continental extension, fault growth, the seismic cycle and seismic hazard. She has shown the long-term spatial distribution of deformation along faults within the Italian Apennines by calculating strain-rates using field measurements of slip-vectors from striated faults and offsets of 15kyr Late Pleistocene -Holocene landforms and sediments. By comparing her results with strain-rates calculated using geodesy and historical seismicity over shorter timescales, she has shown that the spatial pattern of earthquake recurrence is controlled by fault evolution, interaction and sub-crustal processes (Faure Walker et al., 2010, 2012, Cowie et al., 2017, Wedmore et al., 2017). Comparing the fault-derived strain-rates with uplift rates and topography, she has shown how brittle deformation at the surface is related to viscous deformation at depth via a power law as predicted by laboratory equations (Cowie et al., 2013, Faure Walker et al., 2010, 2012). Her work developing the “geometry-dependent throw-rate theory” has demonstrated the role of local 3D geometry (strike and dip) of faults for local throw-rates (vertical component of slip-rate) and hence strain-rates and moment release across faults (Faure Walker et al., 2009, 2015, Wilkinson et al., 2015, Mildon et al., 2016). This has provided a breakthrough regarding breach fault evolution (Faure Walker et al., 2009). Recent work has investigated how detailed fault geometries affect Coulomb Stress Transfer calculations (Mildon et al., 2016, 2017) and slip in individual earthquakes (Iezzi et al., submitted manuscript). 

Faure Walker has participated in post disaster investigations abroad in Japan, Italy and the Philippines, with a particular focus on vulnerability in the transitional phase of recovery and public perception of risk (Faure Walker et al., 2013, 2014, Faure Walker, 2013, D’Ayala et al., 2017). Her findings have highlighted the need to place post-disaster shelter in the context of pre-existing housing conditions including the financial and construction systems (Faure Walker and Crawford, 2017).
 
Teaching Summary

Joanna is the IRDR Director of Studies and Programme Director for the IRDR MSc Risk, Disaster and Resilience. She lectures on natural hazards, vulnerability, risk and their integration into decision-making. She is the module tutor for the UCL masters-level courses: “Integrating Science into Risk and Disaster Reduction” and “Natural and Anthropogenic Hazards and Vulnerability”. Joanna has taught on a number of undergraduate, masters and PhD training modules for UCL and Birkbeck, such as active tectonics, geophysical hazards, structural geology, geology for civil engineers, earthquake seismology and earthquake hazard. She has taught geophysical techniques, geological mapping, and risk assessment on fieldtrips in the U.K., Italy, and Greece.

Joanna has experience teaching to a wide range of audiences. In addition to her university teaching, she has taught on professional training courses covering topics such as earthquake hazard, landslide hazard, extreme events, exposure and vulnerability, data availability, and communicating disaster risk reduction. She was the co-chair for the “Educating Future Leaders in Understanding Risk” session at the Third Understanding Risk Forum organised by the World Bank.
