“…These regional pattern deviations between modeled and observation orientations are mainly induced by differences in the upper mantle density structures and topographies (Heidbach and Höhne, 2007) (compare to Figure 5a). The high density of heat flow data (Pollack et al, 1993;Artemieva, 2006) , respectively.…”

“…The stress field in western Europe is influenced by the North Atlantic ridge (NAR) push in the west and possibly by the far-field slab pull from the north-western Pacific subduction zones, while in the south, the driving forces are induced by the 20 convergence of the African and Eurasian plates, with Africa subducting under Eurasia in the Mediterranean (Zoback, 1992;Müller et al, 1992;Gölke, 1996;Heidbach and Höhne, 2007;Schiffer and Nielsen, 2016). These plate boundary forces combined with the anomalous mantle pressure (Schiffer and Nielsen, 2016) underneath the North Atlantic lithosphere generate the dominant first-order NW-SE stress pattern.…”

“…Also, gravitational effects due to lateral density heterogeneities in the lithosphere and tractions from the mantle flow at the base of the moving plates play an important role. Superposition of different tectonic forces creates dissimilar orientations and regimes of the lithospheric stress field in different regions, as shown by the World Stress Map project (Bird and Li, 1996;Heidbach and Höhne, 2007;Heidbach et al, 2008Heidbach et al, , 2016.…”

Abstract. The orientation and tectonic regime of the observed crustal/lithospheric stress field contribute to our knowledge of different deformation processes occurring within the Earth's crust and lithosphere. In this study, we analyze the influence of the thermal and density structure of the upper mantle on the lithospheric stress field and topography. We use a 3D lithosphereasthenosphere numerical model with power-law rheology, coupled to a spectral mantle flow code at 300 km depth. Our results are validated against the World Stress Map 2016 and the observation-based residual topography. We derive the upper mantle 5 thermal structure from either a heat flow model combined with a sea floor age model (TM1) or a global S-wave velocity model (TM2). We show that lateral density heterogeneities in the upper 300 km have a limited influence on the modeled horizontal stress field as opposed to the resulting dynamic topography that appears more sensitive to such heterogeneities. There is hardly any difference between the stress orientation patterns predicted with and without consideration of the heterogeneities in the upper mantle density structure across North America, Australia, and North Africa. In contrast, we find that the dynamic 10 topography is to a greater extent controlled by the upper mantle density structure. After correction for the chemical depletion of continents, the TM2 model leads to a much better fit with the observed residual topography giving a correlation of 0.51 in continents, but this correction leads to no significant improvement in the resulting lithosphere stresses. In continental regions with abundant heat flow data such as, for instant, Western Europe, TM1 results in relatively a small angular misfits of 18.30

Abstract. The World Stress Map (WSM) database contains over 16,000 indicators on contemporary crustal tectonic stress and provides an essential parameter for geohazard assessment. This paper focuses on the importance of database accessibility for geohazard assessment and presents the basic concepts and availability of the WSM. The WSM can be applied to several key aspects of geohazard assessment, in particular the mapping of stress patterns and places of stress concentration for improved delineation of zones of seismic hazard. Furthermore, contemporary tectonic stresses can be used in combination with numerical modeling to identify faults or sections of fault systems with high failure potential and can help to predict the likely type of fault reactivation. This approach is especially valuable for assessing the likelihood of strong and rare seismic events for which probabilistic hazard assessment will fail and physically based methodologies are required. Herein, we use the Caspian-Caucasian region as an example to apply WSM data for geohazard assessment. The Caspian-Caucasian area is characterized by the occurrence of a number of stress related geohazards on different spatial scales, in particular crustal earthquakes, seismically triggered landslides and mud volcanism.

Regional and local stress field orientation inferred from quantitative analyses of extension joints: Case study from southern Italy

[1] An intense tectonic activity in eastern Sicily and southern Calabria (Italy) is well documented by the differential uplift of Late Quaternary coastlines and by the record of the strong historical earthquakes. The extensional belt that crosses this area is dominated by a well-established WNW-ESE-oriented stretching direction. However, this area is largely lacking of any structural analysis for defining the tectonics at a more local scale. The analysis of systematic extension joint sets affecting Pleistocene deposits presented in this paper allows to infer the causative tectonic stress tensor by means of a quantitative inversion technique. Local perturbations of the first-order regional stress field are consequently recognized. Such perturbations are interpreted as due to interferences between large active faults and their particular geometrical setting. These results contribute to the understanding of the Quaternary tectonic evolution and the present-day stress regime.
