Research project: Controls on Megathrust Earthquake Segmentation

Currently Active: 
Yes

Great earthquakes rupture >1000km2 of a convergent margin with seismic slip of tens of meters. The spatial extent of rupture controls the magnitude and destructiveness of the earthquake. Factors impacting on seismic rupture include topographic features on the oceanic plate, composition and amount of trench sediments and upper plate faults.

Project Overview

Outline of work

Marine seismic and bathymetry data across earthquake boundaries worldwide will be analysed to document structural and morphological variations of the upper overriding and the lower subducting plate which impact on or reflect changes in the physical properties of the plate interface and thus control seismic rupture.
