Growth of Geological Structure & Topography

The relationship between individual earthquakes and the longer-term growth of topography and of geological structures is not fully understood, but is key to our ability to make use of topographic and geological data sets in the contexts of seismic hazard and wider-scale tectonics. Using observations of an earthquake at the edge of the Tarim Basin,…

Kaikoura Earthquake – Complex Rupture & Mountain Building

Working with collaborators at GNS New Zealand (Ian Hamling and colleagues), we have been examining the major Kaikoura earthquake from November 2016 which shook the South Island. By using the latest satellite instruments and data, combined with field observations, we were able to constrain the complexity of this multi-fault rupture and determine the magnitude of uplift…

Seismic Cities

The rapid urbanisation of cities alongside and on top of poorly characterised faults that are has resulted in large populations being exposed to a potentially large hazard. I am leading a recently funded project called Seismic Cities which will attempt to develop a blueprint to better tackle the question and improvement of resilience to earthquakes in…

Hazard in regions of distributed shortening

The 2011 October 23 MW 7.1 Van earthquake in eastern Turkey caused ∼600 deaths and caused widespread damage and economic loss. The seismogenic rupture was restricted to 10–25 km in depth, but aseismic surface creep, coincident with outcrop fault exposures, was observed in the hours to months after the earthquake. We combine observations from radar interferometry, seismology, geomorphology and…
