Evolution of a major segmented normal fault during multiphase rifting: The origin of plan-view zigzag geometry
This case study addresses fault reactivation and linkage between distinct extensional episodes with variable stretching direction. Using 2-D and 3-D seismic reﬂection data we demonstrate how the Vesterdjupet Fault Zone, ...
Record-breaking height for 8000-Year-Old tsunami in the North Atlantic
(American Geophysical Union, 2003-08-05)
The seismotectonics of western Skagerrak
The seismically active Skagerrak region in the border area between Denmark and Norway has traditionally been associated with uncertain earthquake locations due to the limited station coverage in the region. A new seismic ...
Petrophysical Properties of Deformed Sandstone Reservoir
(The University of Bergen, 2012-06-21)
Small scale deformation structures that mostly occur in highly porous rocks are called deformation bands. Petrophysical characteristics of deformation bands are different from those of host rock and they can act as ...
Multidimensional Multirate Sampling and Seismic Migration
(The University of Bergen, 2010-06-01)
Seismic data are usually recorded in time and space on rectangular lattices. Seismic wave propagation is described by the wave-equation, which yields a Fourier spectrum with smaller bandwidth than the rectangular periodicity ...
Influence of frozen ground on seismic data
(The University of Bergen, 2012-08-02)
The interest for subsurface exploration in the arctic is increasing. Thus knowledge about the effects of glaciers and permafrost on seismic data is needed. This thesis focuses on five questions that are relevant in this ...
Simulating the climatic response of Hardangerjøkulen in southern Norway since the Little Ice Age
(The University of Bergen, 2014-05-24)
Glacier and ice cap volume changes currently amount to half of the total contribution from the cryosphere to sea-level rise. Ice caps and their outlet glaciers are dynamically different from the Greenland and Antarctic ice ...
Fracture-generated permeability and groundwater yield in Norway
(Norges geologiske undersøkelse, 2002)
The transport of groundwater in bedrock is largely determined by interconnected fractures and their apertures. The conditions by which fractures become interconnected are thus of primary importance in understanding ...
Experimental investigations of Magnetization processes in Chinese loess
(The University of Bergen, 2011-11-25)
Integration of ground-based hyperspectral and lidar scanning in virtual outcrop geology
(The University of Bergen, 2011-01-28)
The potential to visualize and analyse geological outcrops in a 3D environment has made terrestrial laser scanning (TLS) a standard method in geological field studies. Lidar models can be integrated with high resolution ...
