On September 24, 2016 at 02:11 local time, the Central Romania region was hit by an earthquake with magnitude 5.3. The epicenter of earthquake was in the Vrancea region, 150 km north of Bucharest in depth 92 km (source of information: romanian seismological service).
Earthquakes in this region are quite often. The Vrancea region is the most active seismic zone in the whole Carpathian arc. Some strong earthquakes with fatal consequences occurred there in the past, causing death of many people (Table). This area is characteristic with deep earthquakes, ranging to depth more than 150 km.

The earthquake from September 24, 2016, is visible also on seismic records from seismic stations of the National Network of Seismic Stations (NNSS) operated by the Earth Science Institute SAS (Fig. 1-2). First automatic localization of the earthquake epicenter and magnitude estimation (Fig. 3.) based on seismic records from NNSS were available several minutes after seismic waves arrival. These first estimations correlate very good with the final earthquake parameters provided by the International Seismological Data Center CSEM-EMSC.
