| Zusammenfassung |
| The crustal and sub-crustal seismicity that occurred in the Vrancea area from 1978 to
2008 is investigated. Due to quarry blast contamination, the analysis of the
crustal seismicity was restricted to events that occurred between 20 km and 60 km,
considering sub-crustal events as all those that occurred at depths larger than
60 km. The completeness magnitude was estimated between 2.3 and 2.5 for the
crustal seismicity and between 2.9 and 3.1 for the sub-crustal one. The
Gutenberg-Richter b-values show clear differences between crustal and
sub-crustal seismicity, with values around 0.9 and 1.3–1.4, respectively. The
analysis performed in this study represents a preliminary issue for the
seismic hazard assessment of surrounding regions like Moldova, for which the
earthquakes generated in Vrancea represent an important threat. |
