“…Physics-based thermal models have been constructed for various regions (e.g. Bonté et al, 2012;Freymark et al, 2017;Fuchs et al, 2020;Limberger et al, 2018). Such models require information on the geology of the subsurface and estimates of the thermal properties of the geological units.…”

“…The ES-MDA has also been applied by Fokker et al (2016) for reservoir modeling to constrain subsurface model parameters. More details on the methodology can be found in the IMAGE-D6.01 report (http://www.image-fp7.eu/reference-documents/Pages/default.aspx) and Limberger et al (2018).…”

“…Data assimilation using the ensemble smoother have already been tested in several studies for both large-scale thermal modeling (e.g. Limberger et al, 2018) and ground deformation modeling outside the geothermal sector (Baù et al, 2015;Candela et al, 2021;Fokker et al, 2016). In this thesis I aim a further extension of inversion techniques to geothermal exploration and exploitation, and demonstrate their relevance to better characterize geothermal systems and to reduce risks related to subsurface uncertainties.…”

“…The temperature maps were generated by kriging, showing significant improvements. Large-scale temperature models for Europe including the Netherlands, calibrated with a compilation of temperature models based on measurements were also constructed by Limberger et al (2014Limberger et al ( , 2018. Verweij (2003) further characterized the temperature distribution in the onshore Netherlands using not only temperature measurements but also a physics-based approach, taking into account calculated estimates of the thermal conductivity and heatflow of the main lithostratigraphical units.…”

“…For instance, Fokker et al (2016) constrained the model parameters of a compacting gas field in the Netherlands with ES-MDA using satellite data. Inversion using ES-MDA to calibrate temperature models was previously applied by Békési et al (2018) and Limberger et al (2018). We followed a similar methodology by applying the ES-MDA to constrain the thermal conductivity of the sedimentary units and heat generation in the upper crust.…”

Despite the amount of research focussed on the Alpine orogen, different hypotheses still exist regarding varying spatial seismicity distribution patterns throughout the region. Previous measurement-constrained regional 3D models of lithospheric density distribution and thermal field facilitate the generation of a data-based rheological model of the region. In this study, we compute the long-term lithospheric strength and compare its spatial variation to observed seismicity patterns. We demonstrate how strength maxima within the crust (~ 1 GPa) and upper mantle (> 2 GPa) occur at temperatures characteristic of the onset of crystal plasticity in those rocks (crust: 200–400 °C; mantle: ~ 600 °C), with almost all seismicity occurring in these regions. Correlation in the northern and southern forelands between crustal and lithospheric strengths and seismicity show different patterns of event distribution, reflecting their different tectonic settings. Seismicity in the plate boundary setting of the southern foreland corresponds to the integrated lithospheric strength, occurring mainly in the weaker domains surrounding the strong Adriatic plate. In the intraplate setting of the northern foreland, seismicity correlates to modelled crustal strength, and it mainly occurs in the weaker and warmer crust beneath the Upper Rhine Graben. We, therefore, suggest that seismicity in the upper crust is linked to weak crustal domains, which are more prone to localise deformation promoting failure and, depending on the local properties of the fault, earthquakes at relatively lower levels of accumulated stress than their neighbouring stronger counterparts. Upper mantle seismicity at depths greater than modelled brittle conditions, can be either explained by embrittlement of the mantle due to grain-size sensitive deformation within domains of active or recent slab cooling, or by dissipative weakening mechanisms, such as thermal runaway from shear heating and/or dehydration reactions within an overly ductile mantle. Results generated in this study are available for open access use to further discussions on the region.
