Abstract
The intermediate-depth seismicity from Vrancea seismic region in Romania represents the main source of seismic hazard for Romania and neighbouring countries, with the most recent largest events (M 7.7 and 7.4) known to have caused significant and widespread destruction. The particular characteristics of Vrancea seismogenic volume that fall into category of, so called, “seismic nests”, make it as well of great scientific interest in seismology. In this study we present first results evaluating the performance and capability of an automated network-based full-waveform earthquake detection and location scheme for building a detailed view of seismic activity in space and time with the focus on the intermediate-depth earthquakes from Vrancea seismic source Romania. We make use of case-specific synthetic examples for testing the parameters of the detection and location scheme and analysing the influence of station configuration on the accuracy of events location.
