Analysis of seismic data and correlation with downhole geophysical measurements in theassessment of a Swedish area prone to quick clay landslides
2013 (English)Conference paper, Abstract (Refereed)
The use of geophysics in the investigation of quick claylandslides in Sweden allows to obtain information about thepresence, and possibly even the origin of these kinds ofclays and their physical properties. Geophysical methodsare non-invasive and non-destructive, and if complementedby, for example, geotechnical and hydrologicalinvestigations, can allow a better and improvedcharacterization of the target area.Downhole geophysical measurements such as naturalgamma density, fluid conductivity, fluid temperature and apreliminary classification of the samples from threeboreholes are presented here from our GeoscientistsWithout Borders project in southwestern Sweden. Themeasurements allow not only the constraining of the originof reflections in nearby seismic lines, but also improve ourunderstanding about the way quick clay landslides function.This knowledge contributes significantly to quick claylandslide assessments and mitigating the risks associatedwith them.
