Development of a seismic site-response zonation map for the Netherlands

van Ginkel, J. (author), Ruigrok, E. (author), Stafleu, J. (author), Herber, R. (author)

Earthquake site response is an essential part of seismic hazard assessment, especially in densely populated areas. The shallow geology of the Netherlands consists of a very heterogeneous soft sediment cover, which has a strong effect on the amplitude of ground shaking. Even though the Netherlands is a low- to moderate-seismicity area, the seis...

Uncertainty assessment applied to marine subsurface datasets

Kint, L. (author), Hademenos, V. (author), de Mol, R. (author), Stafleu, J. (author), van Heteren, S. (author), Van Lancker, V. (author)

A recently released voxel model quantifying aggregate resources of the Belgian part of the North Sea includes lithological properties of all Quaternary sediments and modelling-related uncertainty. As the underlying borehole data come from various sources and cover a long time-span, data-related uncertainties should be accounted for as well....

Towards regionally forecasting shallow subsidence in the Netherlands

Candela, T.G.G. (author), Koster, K. (author), Stafleu, J. (author), Visser, W. (author), Fokker, P.A. (author)

The Netherlands is subject to anthropogenically induced deep-source and shallow subsidence. Deep sources are related to the extraction of hydrocarbons or salt mining activities, whereas shallow subsidence comprise compaction, shrinkage and oxidation of clay and peat under progressive lowering groundwater levels. At TNO – Geological Survey of the...

3D subsurface characterisation of the Belgian Continental Shelf: A new voxel modelling approach

Hademenos, V. (author), Stafleu, J. (author), Missiaen, T. (author), Kint, L. (author), van Lancker, V.R.M. (author)

Modelling of surface and shallow subsurface data is getting more and more advanced and is demonstrated mostly for onshore (hydro)geological applications. Three-dimensional (3D) modelling techniques are used increasingly, and now include voxel modelling that often employs stochastic or probabilistic methods to assess model uncertainty. This paper...

Three-dimensional distribution of organic matter in coastal-deltaic peat: Implications for subsidence and carbon dioxide emissions by human-induced peat oxidation

Koster, K. (author), Stafleu, J. (author), Cohen, K.M. (author), Stouthamer, E. (author), Busschers, F.S. (author), Middelkoop, H. (author)

Human-induced groundwater level lowering in the Holocene coastal-deltaic plain of the Netherlands causes oxidation of peat organic matter, resulting in land subsidence and carbon dioxide (CO2) emissions. Here, a three-dimensional (3D) analysis of the distribution of the remaining peat organic matter is presented, to quantify the potential of...

In a geological GIS-data recombination project, a digital map was produced that contains information on the Netherlands’ former coastal and delta plain landscapes over the last 14,000 years: the Holocene and the very end of the Pleistocene. The polygon map product is accompanied by a set of palaeoDEMs (Digital Elevation Models) indicating the...

Characterisation of the Groningen subsurface for seismic hazard and risk modelling

Kruiver, P.P. (author), Wiersma, A. (author), Kloosterman, F.H. (author), de Lange, G. (author), Korff, M. (author), Stafleu, J. (author), Harting, R. (author), Gunnink, J.L. (author), Green, R.A. (author), van Elk, J. (author), Doornhof, D. (author)

The shallow subsurface of Groningen, the Netherlands, is heterogeneous due to its formation in a Holocene tidal coastal setting on a periglacially and glacially inherited landscape with strong lateral variation in subsurface architecture. Soft sediments with low, small-strain shear wave velocities (VS30 around 200ms-1) are known to amplify...

An integrated shear-wave velocity model for the Groningen gas field, The Netherlands

A regional shear-wave velocity (VS) model has been developed for the Groningen gas field in the Netherlands as the basis for seismic microzonation of an area of more than 1000 km2. The VS model, extending to a depth of almost 1 km, is an essential input to the modelling of hazard and risk due to induced earthquakes in the region. The detailed VS...

Generic 3D interpolation of Holocene base-level rise and provision of accommodation space, developed for the Netherlands coastal plain and infilled palaeovalleys

Koster, K. (author), Stafleu, J. (author), Cohen, K.M. (author)

We present an interpolation model that describes Holocene groundwater level rise and the creation of accommodation space in 3D in the Rhine-Meuse delta – the Netherlands. The model area (ca. 12 400 km2) covers two palaeovalleys of Late Pleistocene age (each 30 km wide) and the overlying Holocene deposits of the Rhine-Meuse delta, the Holland...

Aggregate resource assessments, derived from three subsequent generations of voxel models, were compared in a qualitative way to illustrate and discuss modelling progress. We compared the models in terms of both methodology and usability. All three models were produced by the Geological Survey of the Netherlands. Aggregate is granular mineral...

Over the last ten to twenty years, geological surveys all over the world have been entangled in a process of digitisation. Their paper archives, built over many decades, have largely been replaced by electronic databases. The systematic production of geological map sheets is being replaced by 3D subsurface modelling, the results of which are...
