The Vrancea seismogenic area, located at the South-Eastern Carpathians in Romania, is generating extreme destructive subcrustal
earthquakes in Europe. The largest events generated in the last ten years in the Vrancea subcrustal domain occurred on May 14,
2005 (01:53, 45.64oN, 26.53oE, h=149 km, Mw = 5.5), April 25, 2009 (17:18, 45.68oN, 26.62oE, h=110 km, Mw = 5.4) and
October 6, 2013 (01:37, 45.67oN, 26.58oE, h=135 km, Mw = 5.2). The purpose of the present paper is to determine the seismic
source parameters of these events using the Empirical Green’s function deconvolution and spectral ratios techniques. To this aim,
we selected a set of empirical Green’s functions in association with the three main events, as co-located events with similar focal
mechanism. The large number of high-quality waveforms recorded for the main shock-EGF pairs provides a good database to
constrain source parameters, even though the events are relatively small and are recorded practically in the far field. The seismic
moment - source radius scaling and stress drop values range, match well the results as previously obtained on larger data sets.
