ABSTRACT

This paper presents a basic description of the geological and tectonic setting of the areas of placement of four seismological observatories located in the eastern part of Romania. The four seismological observatories are MLR – Red Mountain Seismologic Observatory, NEHR – Nehoiu Mountain Seismological Observatory, ODBI – Odobesti Seismological Observatory and VRI – Vrancioaia Seismological Observatory. This observatories were chose because of their importance and proximity to the seismic active Vrancea region. Many geologic studies, of this areas, were carried out through time, resulting in a vast literature, studies, several geologic sections and maps. This descriptions were compiled from the geologic and tectonic maps, geologic sections, studies and literature, mentioned above, for every location of the observatories. For each one, of the sites, a geotectonic map was drawn, showing the main geologic formations and tectonic features. This geotectonic information was synthetized to add a better view to the lithological and tectonic history of each of the sites. Through this paper, we hope to provide clearer information and understanding of the geology and tectonics in which the mentioned observatories are set.

Keywords: geology, tectonic, seismologic observatories.
