Earthquake Seismology

Stephen’s research aims to answer a variety of scientific problems surrounding earthquake ruptures, tectonic plate boundaries, and dynamic processes in the Earth's solid interior. Stephen has published worked on subduction zone plate boundaries, which have helped to develop life on Earth, but they have the power to take life away during damaging earthquakes and volcanic eruptions. Stephen uses recordings of seismic waves from earthquakes to probe the complex 3-D subsurface structure of subduction zones and to understand the mechanics of large earthquake ruptures.

Prior to starting at Imperial College, Stephen worked in the Department of Ocean and Earth Science at the University of Southampton where he worked on the NERC large consortium VoiLA project. Stephen also previously held a commercial position at Güralp Systems Ltd, where he worked on complex seismic monitoring projects such as ocean bottom seismometer observatories and earthquake early warning systems.

Stephen completed his PhD in Earthquake Seismology at the University of Liverpool, UK. His PhD thesis revealed how the ancient geological structure beneath South America can still drive the rupture characteristics of modern-day large earthquakes. With co-authors, he also showed how possible ‘doublet’ earthquakes may be hidden from global monitoring networks. This finding may help to optimise tsunami warning systems in the future. From his PhD thesis, he published four papers in international peer-reviewed scientific journals, including one article in Nature Geoscience.

In 2009, Stephen spent a summer working at the United States Geological Survey (USGS) National Earthquake Information Center (NEIC). He also has experience in seismometer deployments and fieldwork across the globe.

Stephen blogs on popular earth science topics and he is available for media work.
