Ground and infrastructure stability are important for our technologically based civilization. Infrastructure projects take into consideration the risk posed by ground displacement (e.g., seismicity, geological conditions and geomorphology). To address this risk, earth scientists and civil engineers employ a range of measurement technologies, such a...

The Moesian Platform represents a major tectonic unit of the foreland of the Carpathians and Balkans, spanning across the southern part of Romania and the northern part of Bulgaria. Although the Moesian Platform is considered to be a stable tectonic unit, it has played a significant role in the geological history of the region, influencing the deve...

Mangalia area harbors in the western Black Sea a distinctive marine environment thriving under specific hydrochemical conditions, largely influenced by a significant number of sulphurous springs occurring in shallow marine waters. These springs led to the designation of the area as part of the Natura 2000 Marine Protected Area (MPA) network at Euro...

Due to spectacular advances in Geology during the XXth century, plate tectonics and active tectonics on a dynamic Earth may be considered as main natural phenomena involved in the generation of continental, regional or local seismicity. When searching for additional components that sometime may represent a trigger for strong seismic events, gravita...

There are already numerous attempts to scientifically relate seismicity to a number of precursors in seismologically active areas. There are also attempts to identify phenomena that may trigger the seismic events, especially the high magnitude ones, such as active tectonics or the Sun – Earth – Moon gravitational interactions. When studying the ROM...
