The tectonic geomorphology of bedrock scarps on active normal faults in the Italian Apennines mapped using combined ground penetrating radar and terrestrial laser scanning.
Using combined datasets from ground penetrating radar (GPR) and terrestrial laser scanning (TLS) we document the variety of tectono-geomorphic features that contribute to the morphology of bedrock scarps associated with active extensional faulting in central Italy. Measurement of faulted offsets across such scarps can provide important fault slip-rate data relevant to seismic hazard analysis if…

Control of fault geometry and mechanical stratigraphy on normal fault-related folding: a case study from Inner Moray Firth Basin
Deformation in the volume surrounding normal fault zones in sedimentary sequences is often accompanied, on a range of scales, by ductile flexure of the beds, which may evolve into drag folds. These folds can be the result of various processes throughout different periods of the fault system evolution, such as fault propagation folding (Withjack et…
Read MoreA Lambert W function solution for estimating sustainable injection rates for storage of CO2 in brine aquifers.
It is often of interest to estimate the maximum possible CO2 injection rate for a given maximum pressure buildup and injection duration scenario. Analytical solutions exist to estimate pressure buildup due to constant rate injection for a specified duration. In this article, it is shown that such solutions can be rearranged for injection rate by…

Verification of velocity-resistivity relationships derived from structural joint inversion with borehole data.
We present results of three-dimensional joint inversion of seismic, magnetotelluric, and gravity data over a marine salt dome. Such structures are difficult to image with a single method, and our results demonstrate how combining different techniques can yield improved results. More importantly, we examine the reliability of velocity-conductivity relationships derived from structure-coupled joint inversion approaches.…

Mapping turbidity layers using a combination of high resolution seismic oceanographic and physical oceanographic data
Synchronised seismic and oceanographic data were acquired during the GO (Geophysical Oceanography) project cruise in the Gulf of Cadiz in April – May 2007. The small volume (117 cu-inch) mini GI-gun seismic source used during the GO experiment provided high resolution seismic data which revealed features of the internal structure of the ocean. The seismic…
