The seismicity of the South Western part of Romania is linked to tectonic deformation being the result of the dextral movements at the contact between the Carpathians Orogen and Moesian Platform. The most notable active faults in this region are the Oravita-Moldova Noua Fault and Cerna-Jiu Fault. The crustal structure of this region was investigated through classical and modern techniques such as refraction and reflection profiling, seismic tomography, joint inversion of dispersion curves, and receiver functions. Targu-Jiu region was characterized before 2023 by sporadic small to moderate earthquakes. A well-investigated seismic sequence was produced in 2011-2012. The recent double-shock occurred in the area in February 2023 (5.2 and 5.7 ML) and was followed by more than 700 aftershocks. In order to estimate an improved 1-D velocity model for this active region, we extracted from the Romanian earthquake bulletins 170 events, recorded by Romanian Seismic Network. The events were selected based on the following criteria: a minimum of 20 recorded phases for each individual earthquake, the RMS location of less than 1 second, and a maximum azimuthal gap of 180 degrees. The region's velocity model and station corrections were accurately determined by minimizing the misfit between the model predictions and arrival times. The VELEST algorithm was run on the selected data, using P and S-wave travel times and the initial velocity models for generating new improved velocity models. We noticed a reduction of up to 40% in RMS location errors for all resulting velocity models., The 28th IUGG General Assembly (IUGG2023) (Berlin 2023)

Carbon dioxide emissions, global warming, ocean acidification, habitat destruction, extinction, and widescale natural resource extraction are all signs that we have significantly modified our planet, resulting in the need to consider the Anthropocene as a new geological era. CCS is an appropriate solution for reducing CO2 emissions in the Earth's atmosphere. Over the last 25 years, our teams have initiated several CCS projects, the latest being CO2-HyBrid, which strongly contributes to the decarbonization of the energy and industrial systems in a sustainable and resource-efficient way. In the first stage, membranes have a very low footprint and their operation is sustainable, as it has low energy consumption and no impurities in the main stream. In the second stage, the chemical absorption process has a higher rate of capturing CO2 with lower thermal energy consumption for the chemical solvent. Finally, the solution demonstrates reliability and flexibility, achieving CO2 quality suitable for storage. All our efforts significantly contribute to realizing the objectives of the well-known Paris Agreement. Although humanity has caused global warming, applying CCS can significantly reduce this phenomenon, making it a compelling argument for adopting the term Anthropocene to describe the effects of human actions on the Earth. Moreover, public acceptance is crucial for the implementation of CCS technology. The CO2 artificial deposits resulting from CCS are key elements of the Anthropocene, among others., The 28th IUGG General Assembly (IUGG2023) (Berlin 2023)

Foreland basins are dependent on two key parts, a ���moving part��� (the fold and thrust belt) and a relatively ���stationary part��� (the pre-existing basins). Throughout the study area multiple wells drilled the pre-Miocene stratigraphy from multiple basins (East European Platform, B��rlad Depression, North Dobrogea Promontory, East Moesian Platform) and each basin had a different response for the E-ward advancing Carpathians. The older and colder the plates, the more rigidly they responded to the advancement of the nappes and a new pre-foreland setup was established through creation of multiple depocenters across the basin. The pre-existing topography played an important role for foreland geometry and fill. Main findings show that the Northern foreland didn���t advance too far away as the East European Platform broke apart on long N-S fault zones rather than flexing and creating too much accommodation space for the Miocene fill. Further to the South we observe that the nappes had more space to advance, and this seems to be related to the response of the B��rlad Depression, as weaker plate flexing easily under the load and generating a rapid subsiding foreland basin. This area shows the highest subsidence rate for the Sarmatian section (Bacau area). Further to the South as the Carpathians hit the toughest block, the Nord Dobrogea Promontory (made up of Palaeozoic sediments and metamorphic basement rocks), the advancement of the thrust belt found advancing to the East as difficult as it can possibly be, thus the weakest link in the area (East Moesia), started flexing and creating large accommodation space starting with Sarmatian and through time until Romanian-Quaternary times., {"references":["Airinei, S., Boisnard, M., Botezatu, R., Georgescu, L., Suciu, P., Visarion, M.

We define and classify minimal translation surfaces in the 3-dimensional Heisenberg group H(1,1).

This study aims to bring new constraints on the Eocene stratigraphy of the northern edge of Istria Basin, located in Western Black Sea. For achieving our goal, we have studied several core reports containing the description of the lithology and microfossils assemblages (foraminifera, ostracods and calcareous nannofossils) from 3 wells drilled in the northern Istria Basin. Thus, we were able to identify lithological and biostratigraphic constraints, allowing to generate a coherent correlation scheme for the Eocene deposits, with precise age assignment and advanced models of the IB evolution during the Eocene. The lithology of the 3 wells, situated in the Sinoe, Lebăda West and Lebăda East areas, is mainly represented by calcareous sandstones and siliciclastic ones. The biostratigraphy indicates that the deposits of the Sinoe and Lebăda West wells are Middle Eocene in age (mostly the upper part), while in the Lebăda East well a late Early to Middle Eocene age was assigned., {"references":["Agnini C., Muttoni G., Kent D.V., Rio D., 2006.

The civilisation is in the continuous search for energy resources, either already in use or new ones, for future needs. The gas hydrates are one of the unconventional resources that have been identified, evaluated and in the future will be probably exploited. The semi-enclosed Black Sea Basin has an excellent potential for free gas and gas hydrate accumulation, on account of its anoxic water regime which favours the preservation of organic matter in the sediments (the chemocline lies at 110–140 m depth). Regions outside the stability field of gas hydrates, namely, the shelf and upper slope, show a high gas content in the sediments. The Black Sea Basin has been the focus for numerous research projects, which led to the identification of the BSR that might be associated with the gas hydrate zones. Beside the gas hydrates, numerous gas occurrences have been recognized on the seafloor of the Black Sea in different sectors and at different depths, including shelf and slope of Romanian Black Sea area, and a significant amount of data have been published. The current synthesis aims to make a review of the results published in the last 15 years describing geological structure and evolution of the Black Sea Basin, as well as bottom sediments, gas hydrates, flare and escape structures Offshore Romania., {"references": ["Afanasenkov, A.P., Nikishin, A.M., Obukhov, A.N., 2007.
