The seismic refraction reversed profiling technique has been used to investigate the topography of the last interglacial soil (paléosol S1) within the central Chinese Loess Plateau near Xifeng: variations in the depth. Discussion about the results
Seismogenic nodes - specific structures formes at the intersections of fault zones - have been delineated in this paper by the morphostructural zoning (MZ) method and their seismic potential has been evaluated by the pattern-recognition method
L'A. montre les apports et les limites des méthodes de réfraction sismique pour l'étude et la différenciation des sédiments meubles. Des études de cas menées en Allemagne, au Baden-Wurtemberg (Bietigheim, Untergrombach, Kirchener Tal, Maustobel
Durant la dernière décennie, on a appliqué la réfraction sismique à la recherche géomorphologique. Mais l'interprétation des données étant limitée à une méthode, les AA. proposent des méthodes de modélisation en deux dimensions appropriées à un
High-resolution seismic and ground penetrating radar - Geophysical profiling of a thermokarst lake in the western Lena Delta, northern Siberia

High-resolution seismic and ground-penetrating-radar (GPR) data have been acquired over Lake Nikolay in the western Lena Delta in order to study the uppermost basin fill and the bordering frozen margins. GPR measurements were completed on the frozen
lake and its permafrost margins, while high-resolution seismic data were acquired from the lake during open-water conditions in summer using a Chirp profiler. The combined use of the 2 profiling systems allows stratigraphic profiling in both frozen
Depositional environments and history of Late Quaternary sediments in Hudson Strait and Ungava Bay : further evidence from seismic and biostratigraphic data
Provenance and dispersion of fluvial, beach and shelf sands in the Bassa Maremma coastal system (central Italy): an integrated approach using Fourier shape analysis, grain size and seismic data
, seismic interpretations of 2 new seismic reflection profiles and borehole logs allow better consolidation of the geometry and evolution of the Tuscan Nappe boudins in this region.
Basic regional crustal setting and superimposed local pluton-intrusion-related tectonic in the Larderello-M. amiata geothermal province, from integrated CROP seismic data
Loess-paleosol and paleoclimatic investigations. Principles, methods and criteria
Dynamic characteristics of loess landslides of seismic origin and an approach for predicting landslide in loess are presented. Subsidence of seismic origin in loess is described.

During the 1997 summer field season, a grid of 30 survey stations was established on the high ice plateau in order to locate exactly the ice-flow divide between the Llewellyn and Matthes glaciers. Two geophysical methods, seismic reflections
Mapping of mountain permafrost using geophysical methods
This paper gives an overview of investigations to map mountain permafrost distribution showing the potential of the modern use of geophysical methods : bottom temperature of the snow cover (BTS), refraction seismics, DC resistivity, ground

of the Baltic. Aerial photographs and topographic maps were used. The vertical extent of the deposits and the positions of the underlying bedrock surface were investigated with seismic equipment.
This paper reports new core data and seismic ties to DSDP Site 111 on Orphan Knoll which support a suggested chronology and permit quantification of the volumes of sediment carried through the Trinity Transverse Trough during past glacier advances.
