Small-throw seismogenic fault segments hidden in the Holocene sediments are crucial but difficult targets in seismic exploration. We report here the detection of the deformation pattern and a concealed fault segment in the unconsolidated sediments at Vila Franca Xira, Portugal, through identification in shear wave reflection data of multiple...

The definition of appropriate places for the development of paleoseismic studies is extremely important in earthquake engineering site investigations. The seismic reflection method is routinely used to locate shallow fault segments where these do not outcrop, like in low slip-rate areas where faults identified in Quaternary sediments have...

When applying seismic interferometry to image sub-vertical salt flanks or structures with large dips from vertical or deviated wells, we are often confronted with poor target illumination. Strong directionalillumination footprints caused by non-ideal placement of sources at the surface degrade the interferometric image quality and may prevent...
