The moderate-size earthquake with local magnitude 5,7 which occurred on November 22, 2014 in Vrancea region, at 41 km depth, is the largest crustal event instrumentally recorded at the bending of the Eastern Carpathians. Using the method developed by [2] termed the Hash method, (incorporated in Seisan software) we obtain the focal mechanisms for earthquakes that occurred in Vrancea region associated with the seismic sequence of November 22, 2014. We have examined the main shock and 29 aftershocks that occurred aft...

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 пїЅ Red Mountain Seismologic Observatory, NEHR пїЅ Nehoiu Mountain Seismological Observatory, ODBI пїЅ Odobesti Seismological Observatory and VRI пїЅ Vrancioaia Seismological Observatory. This observatories were chose because of their importance and proximity to the seismic active Vrancea reg...

The active stress pattern in the Apuseni Mts area is investigated and studied in relation to the local seismicity and geology. Our analysis is based on several high quality and resolution data bases obtained recently in the context of national and international projects and which refers to digital seismograms recorded by dense networks, parametric earthquakes catalogues and catalogues of focal mechanisms. The reduced stress tensor has been obtained by formal inversion of 89 focal mechanisms solutions. The maximum ...
