The epicenter was located in the northeastern part of the Vrancea Mountains (45.9 N 26.9 E), at a depth of 89 km. The earthquake had a magnitude of GR 6.7 or w 6.9, the intensity in the epicentral area being of VIII degrees on the Mercalli intensity scale, and VII degrees in Bucharest. On the morning of 31 May 1990, at 3:17 (local hour), occurred the second mainshock, at a depth of 79–86 km, having the magnitude GR 6.1 or w 6.3. The event was felt in the epicentral area with an intensity of VII degrees on the Mercalli intensity scale, and VI degrees in Bucharest; likewise, the quake was felt strong enough in Dobruja. In the USGS EXPO-CAT database it is estimated that during this earthquake 355,000 people were exposed to intensity VII, of which around 61% were in rural areas. Aftershocks The first mainshock was followed by several aftershocks with magnitudes ranging between 3–4.5 degrees on the Richter scale, reported in the afternoon and evening of 30 May. On the morning of 31 May 1990, continued the replicas of the two mainshocks. Thus, at 7:48 (local hour) occurred a replica of magnitude 4.7, felt in Bucharest with an intensity of IV degrees on the Mercalli intensity scale. Other replicas of lower magnitudes continued to occur in Vrancea until the end of June 1990, in the depth floor of 70–90 km. Secondary seismic movements, at the same depth, were recorded and later, until October 1990.
