“…It should be observed that this model, which has a good consistency with the CRUST1.0 model [53], in the considered area is not properly constrained with seismic profiles. This is confirmed also by the predicted map of the Moho depth uncertainty, which ranges between 4 and more than 8 km (STD), in the study area [51]. In order to evaluate the accuracy of the obtained results, three factors should at least be considered: namely the accuracy of the inversion algorithm, the accuracy of the gravitational field data, and the accuracy of the different models used within the data reduction step.…”

“…A set of available seismic profiles (see red lines in Figure 2) has been exploited to constrain the model. In detail, seismic profiles from [39,49] bounded by the information retrieved from the receiver functions [50,51] have been used.…”

“…In Figure 10, the European Moho model [51] and the GEMMA1.0 global model [1] are chosen for comparison purposes. Neglecting the different spatial resolution of the models, it can be observed that the GEMMA1.0 model is able to retrieve the major Moho variation in the considered area, even if different long-wavelengths can be easily observed.…”

Abstract:The study of the discontinuity between the Earth crust and upper mantle, the so-called Moho, and of the lithospheric architecture in general, has several important applications in exploration geophysics. For instance, it is used to facilitate the inversion of seismic-related data, in order to obtain important information on the sedimentary layers or to study the Earth's heat flux. In this paper, the Levant crustal structure is being investigated starting from the inversion of gravity disturbances coming from a global geopotential field model based on ESA GOCE satellite mission integrated with seismic derived information. In the considered area, which is of particular interest because of its richness from the resources point of view, the deep crustal structure is still a matter of study due to the presence of a thick sequence of sedimentary layers, deposited within geological eras by the Nile River. Within the current work, the shape of the Oceanic domain in correspondence to the Herodotus Basin and the Cyprus Arc has been clearly defined. Moreover the nature of the Levantine Basin and of the Eratosthenes crust has been investigated by a set of ad hoc tests, finding the presence of continental crust. Finally, the Moho depth and the crustal density distribution have been retrieved. Several localized anomalies, in the Cyprus area, have been identified and modelled too, thus confirming the presence of heavy material, with a thickness up to 10 km, in the sedimentary layer and shallower part of the crust.

“…Apart from the inherent trade‐off between H and Vp/Vs , the main sources of error when using H − κ technique to explore young orogenic areas, such as the Dinarides, are the assumptions of flat, nondipping Moho interface, and the one of a single‐layered, isotropic crust. Grad and Tiira () give an overview of other possible sources of error in H − κ analyses, and Lombardi et al () use synthetic PRFs to warn of overestimation of H by the H − κ method for dipping interfaces. Li et al () performed a thorough analysis of the adverse impact that Moho dip and crustal anisotropy have on estimated H and κ , and Ogden et al () also analyze the considerable influence of gradational Moho, heterogenous crust, and the choice of processing parameters on the final results.…”

Knowledge about the crustal thickness is one of the key elements in the reconstruction of the regional tectonic history. The Dinaric mountain belt is one of the most enigmatic segments of the Alpine-Mediterranean collision zone, characterized by large variations in crustal thickness and not studied sufficiently. We present a new Moho depth map for the wider Dinarides region which was created using teleseismic earthquake recordings from 87 permanent and temporary seismic stations in the region. Teleseismic data were analyzed using the receiver function method to extract converted P to S waves. The resulting Moho topography fits well within a structural framework comprising a thicker crust under the Dinarides, which gradually becomes thinner toward the Pannonian and Adriatic domains. The profiles crossing the northwestern Dinarides are marked by a relatively sharp decrease in crustal thickness north of the main thrust front. This transition is followed by significant crustal thinning toward the Pannonian basin. The Mohorovičić discontinuity lies the deepest in the central and southern Dinarides, at depths of over 55 km. Here similarly to the northwestern segment we observe a jump in the crustal thickness when transitioning toward the Internal Dinarides, which hints at possible underthrusting (or subduction) of the Adria plate in this region. Moho depths in the transition zone toward the Pannonian basin and in the Pannonian basin proper vary between 25 and 35 km. In the Adriatic domain, we find crustal thickness ranging from 30 km to more than 45 km around the Central Adriatic islands.

“…The P-to-S conversion (Ps) from the Moho is typically one of the most prominent phases on P-wave RFs. Estimates of the depth and thickness of the Moho (e.g., Grad and Tiira, 2012) and V P =V S ratio of the crust are important goals of many RF investigations (Zhu and Kanamori, 2000). In addition, S-to-P conversions (Sp) on S-wave RFs have been used to image the lithosphere-asthenosphere boundary (e.g., Rychert et al, 2005Rychert et al, , 2007Abt et al, 2010;Kumar et al, 2012).…”
