“…In the case of BURAR, many observed deviations can be directly connected with the known slab subduction in the Vrancea area, Romania. Sanina et al (2011) They used data observed at the temporary, small-aperture TRISAR array installed on the Peloponnese in Southern Greece, and at several three-component stations of the Hellenic Seismographic network. Despite the large extent of the aftershock region, which limited the waveform similarity level within the studied aftershock volume, cross-correlation analysis applied on a single array was proven a useful tool, especially for remote regions that cannot be adequately covered by a conventional, regional network (e.g., offshore areas).…”
