Marine palaeoseismology from very high resolution seismic imaging: the Gondola Fault Zone (Adriatic foreland)

High-resolution lithospheric imaging with seismic interferometry

In recent years, there has been an increase in the deployment of relatively dense arrays of seismic stations. The availability of spatially densely sampled global and regional seismic data has stimulated the adoption of industry-style imaging algorithms applied to convertedand scattered-wave energy from distant earthquakes, leading to relatively high-resolution images of the lower crust and upp...

Shallow architecture of the Wadi Araba fault (Dead Sea Transform) from high-resolution seismic investigations

In a high-resolution small-scale seismic experiment we investigated the shallow structure of the Wadi Araba fault (WAF), the principal fault strand of the Dead Sea Transform System between the Gulf of Aqaba/Eilat and the Dead Sea. The experiment consisted of 8 sub-parallel 1 km long seismic lines crossing the WAF. The recording station spacing was 5 m and the source point distance was 20 m. The...

Seismic reflection imaging of the Mount Rose fault zone, Reno, Nevada

From Geodetic Imaging of Seismic and Aseismic Fault Slip to Dynamic Modeling of the Seismic Cycle

Understanding the partitioning of seismic and aseismic fault slip is central to seismotectonics as it ultimately determines the seismic potential of faults. Thanks to advances in tectonic geodesy, it is now possible to develop kinematic models of the spatiotemporal evolution of slip over the seismic cycle and to determine the budget of seismic and aseismic slip. Studies of subduction zones and ...

Coal seismic diffraction fault imaging: Results from numerical modelling

Modern underground coal mining requires certainty about geological faults and other structural features for safety reasons. Even a fault with a throw of a few metres can create safety issues and lead to costly delays in mine production. To ensure there are no unwelcome surprises concerning seam conditions during mining, seismic reflection surveys have been widely used by Australian coal mines, ...
