Unfaulting seismic images to correlate seismic reflectors across faults is helpful in seismic interpretation, and is useful for seismic horizon extraction. Methods for unfaulting typically assume that fault geometries need not change during unfaulting. However, for seismic images containing multiple faults and, especially, intersecting faults, this assumption often results in unnecessary distor...

Seismic base isolation are devices that used to limit the human and material damage caused by an earthquake. This devices diffuse the energy induced at the time of the earthquake before being transferred to the structure.The base isolated structures when subjected to the near-fault eathquakes which contain long-period velocity pulses that may coincide with the period of base isolated structures...

We report on the design and performance of small optic suspensions developed to suppress seismic motion of out-of-cavity optics in the input optics subsystem of the Advanced Laser Interferometer Gravitational Wave Observatory. These compact single stage suspensions provide isolation in all six degrees of freedom of the optic, local sensing and actuation in three of them, and passive damping for...

this study aims to develop seismic fragility curves for a typical pile-supported wharf. fragility curve is one of the popular tools in seismic performance evaluation of a structure. the software flac2d was used to simulate the seismic performance of the wharf structure. using eight time history records, occurred in past, as seismic loading, incremental dynamic analysis (ida) was applied for sei...

Seismic isolation devices, as known, are particularly efficient tools for the protection of newly designed or existing buildings and infrastructures mitigation maximum effects due to earthquakes. The highest is vulnerability a given construction, higher benefit in structural terms possible retrofit intervention based on base isolation. This especially case reinforced concrete (RC) building fram...

Using a combination of seismic oceanographic and physical oceanographic data acquired across the FaroeShetland Channel we present evidence of a turbidity layer that transports suspended sediment along the western boundary of the Channel. We focus on reflections observed on seismic data close to the sea-bed on the Faroese side of the Channel below 900 m. Forward modelling based on independent ph...
