Marmureanu said only small earthquakes of magnitudes higher than six degrees on the Richter scale have occurred in Romania over the past 30 years, and stressed a „catastrophic earthquake” in Vrancea, eastern Romania, means one measuring over seven degrees.
According to Marmureanu, Romania annually faces a large number of small earthquakes of magnitudes below four degrees on Richter scale, which trigger no catastrophic earthquakes. Marmureanu underscored the institute has state-of-the-art equipment that can detect even an earthquake of 0.02 degrees.
The institute reported on its website that nine earthquakes of magnitudes below three degrees on Richter scale have occurred this week in Romania.
The Vrancea area is known for frequent seismic movements and historical analyses show three earthquakes of magnitudes higher than 7.2 occur throughout a century. The most recent high magnitude quakes in Vrancea occurred in 1940, 1977, 1986 and 1990.
