Analysis of the Seismic Activity in the Vrancea Intermediate-Depth Source Region During the Period 2010–2015

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 = 3.8.
