4.4. Specific objectives and deliverables of TOPO-EUROPE

 

Specific objectives of TOPO-EUROPE are:

  • Modelling land subsidence in the basins and deltas of Europe
  • Quantification of land slope instabilities
  • High resolution monitoring of crustal motions in space and time to quantify sediment source-to-sink relations and to constrain earthquake and evolutionary mountain building models
  • Coupling of numerical and analogue modelling schemes for characterising the feedback relationships between tectonics, topography, and climate
  • High resolution tomographic images of the (dynamic) interaction between the (deep) mantle and lithosphere, and its effects on surface topography
  • Studying the effects of neotectonic processes on river and coastal evolution, with emphasis on flooding potential

 

Specific deliverables for the programme at large will include:

  • Deployment of EUROARRAY
  • New models for the sub-lithospheric mantle of Europe based on integration of seismic tomography data
  • New lithospheric thickness, strength and strain-rate maps for each study area and for all of Europe
  • Revised Moho depth and a crustal thickness map for Europe
  • Paleogeographic maps showing the evolution of the European drainage system, sedimentary basins and topography during the last 20 Myr
  • Compilation of regional neotectonic maps of Europe, showing uplift and subsidence as well as lateral displacement rates
  • Quantification of land subsidence rates in evolving basins and deltas and identification of controlling mechanisms
  • Quantification of land uplift rates in active orogens and identification of controlling mechanisms
  • Quantification of intraplate uplift/subsidence rates induced by lithospheric folding and other processes
  • New concepts on tectonic controls of river systems
  • Determination of source-to-sink relations to quantify sediment budgets
  • Improved understanding of driving mechanisms controlling Aegean extension and subduction and uplift of the Apennines
  • Improved 3-D density, electrical resistivity, seismic and thermal structural information for key features
  • Evaluation and understanding of new satellite gravity and geodetic datasets
  • Shallow and deep characteristics of active fault systems
  • Improved seismic hazard maps for natural laboratories

 

Examples of deliverables for some of the selected natural laboratories include:

  • Physical model of stress and strain evolution during the past 10k years along fault systems of the NAFZ, Aegean extension zone, and Dead Sea Rift transform permitting to assess the stress transfer between faults and the time-dependence of seismic hazard
  • Reconstruction of the evolution of uplift, erosion, sedimentation, river systems, seismicity around the SE-Carpathians in comparison to Iberia, both of which are strongly influenced by ongoing lithospheric delamination
  • Data assimilation and modelling of the Fennoscandian uplift, concurrent large extensional earthquakes and major tsunami-creating landslides by using precise data on topography, timing and (paleo)climatic conditions
  • Balance of crustal deformation during the Quaternary and comparison with co-seismic strain rates from historical catalogues and paleo-seismicity in seismically very active areas close to plate boundaries (e.g. Iberia, Apennines, Carpathians, Greater Caucasus, Eastern-Mediterranean) and seismically moderately active intraplate areas (e.g. Rhine Graben, Fennoscandia) with the aim to constrain the relation of and conditions for a-seismic and catastrophic slip
  • Reconstruction of the evolution of Cenozoic vertical movements in the southern part of the East-European Platform to assess the role of deep mantle processes in reworking of the cratonic lithosphere.
