“…The causative relationship between mantle and shallow events was investigated by some authors (e.g. Mitrofan et al, 2014) who showed that focal depths decrease towards the actively subsiding foreland basin (i.e. Focsani Basin, Fig.…”

“…These events are probably related to some extent to the geodynamics in the mantle beneath the Vrancea region. However, this is still a controversial issue [6,7,33] and therefore understanding the interdependence of the tectonic stress in the mantle and coupling and crustal seismicity requires further investigation.…”

Romanian seismicity is mainly confined to the Eastern Carpathians Arc bend (ECAB), where strong subcrustal earthquakes (magnitude up to 7.9) are generated in a narrow lithospheric body descending into the mantle. The seismic activity in the overlying crust is spread over a larger area, located mostly toward the outer side of the ECAB. It is significantly smaller than subcrustal seismicity, raising controversies about possible upper mantle-crust coupling. A significant earthquake sequence took place in the foreland of the ECAB triggered on 22 November 2014 by a mainshock of magnitude 5.7 (the greatest instrumentally recorded earthquake in this region) located in the lower crust. The mainshock triggered a significant increase in the number of small-magnitude events spread over an unusually large area in the ECAB. The paper’s goal is to compute the source parameters of the earthquakes that occurred during the aforementioned sequence, by empirical application of Green’s function and spectral ratio techniques. Fault plane solutions are determined using multiple methods and seismicity evolution at regional scale is investigated. Our results highlight a still active deformation regime at the edge of the EE Craton, while the source parameters reveal a complex fracture of the mainshock and a very high-stress drop.

“…The paper highlights some of the particularities of Romanian heritage, approaching mining and infrastructure heritage in Romania, including several endangered sites. Sometimes, the underground built heritage is threatened by anthropogenic works or natural factors such as high magnitude seismic shocks with epicentres in Vrancea area (Mitrofan et al, 2014, Mitrofan et al, 2016 or other seismogenic areas (Diaconu and Chitea, 2018).…”

This paper approaches the particularities of Romanian heritage, from the view point of endangered mining sites and infrastructure. Several examples are addressed, including: i) salt mines, particular example of successful conversion of Turda salt mine in an underground leisure center; ii) mining heritage, the saving of Roman galleries from the Rosia Montana region, which are the living evidence of 2000 years of gold mining on Romanian territory; iii) the infrastructure heritage, with the example of Suceava water plant, where a concrete half tube with no windows was buried by a slope greened with geotextile reinforced earth, reconstructing the landscape.
