Abstract
The goal of this study is to analyze the seismic activity of the Vrancea intermediate depth source zone during the period 2010–2015, time interval when the data provided by the National Seismic Network reached high quantitative and qualitative levels. The Vrancea undercrustal source (60–200 km depth) is located in a small focal volume at the Carpathian Bend, and it dominates the seismicity of Romania. The data set consists of 1603 earthquakes with local magnitudes 1.8 ≤ ML ≤ 5.5, recorded between January 2010 and October 2015. The events were localized using ANTELOPE software for data acquisition and processing. The reliable P-wave polarities were used to estimate the focal mechanism of 80 earthquakes with ML ≥ 3.8.
