Project 5: The seismic cycle on decadal to millennial scale

In this project, observations from several time scales along the Maule rupture zone will be integrated with the pattern of observed and modelled coseismic deformation. At the decadal scale, 'historical' earthquakes will be revisited by recovering old seismic data, and inverting the coseismic rupture using modern methods. Time series of relative sea-level change and high resolution topographic surveys of geomorphic features will quantify interseismic coupling and upper-plate deformation on the time scale of a seismic cycle. At the millennial scale, the along-strike variation in uplift rates will be obtained from mapping and dating marine terraces and a complete paleoseismic record including variability in rupture lengths will be derived from offshore turbidite deposits.
