An earthquake with magnitude of 4.1 degrees on the Richter scale occurred on Wednesday, at 5:10 am, in the seismic region of Vrancea, with the epicentre in Buzau County, according to the National Institute of Earth Physics (INFP), Realitatea TV announced.
The seism occurred at a depth of 145 kilometres.
The closest cities to the epicentre are: Covasna (36 km), Valenii de Munte (47 km), Sacele (50 km), Targu Secuiesc (52 km) and Sfantu Gheorghe (55 km).
Another earthquake, ranging 4.1 degrees on the Richter scale, occurred on Monday, in Vrancea County, at a depth of 17 kilometres. Mircea Radulian, the scientific director of the National Institute of Earth Physics (INFP) declared for Mediafax that the seism was at the surface and that this kind of earthquake is usually followed by several replies, yet these are of reduced amplitude and are not supposed to be over 3.1 degrees.
On Tuesday, in Vrancea, there were two more earthquakes of over 2.5 degrees on the Richter scale, respectively of 3.2 and 2.8 degrees.
In January, in the seismic region of Vrancea other seven earthquakes were registered previously, ranging from 3.2 to 4.3 degrees on the Richter scale, and the strongest of them, with its epicentre in Buzau County, was registered on January 4.
On November 22, 2014, an earthquake of 5.7 degrees occurred in Vrancea and was registered as the one with the greatest amplitude in Romania for the last ten years. The earthquake was felt in Bucharest as well and was followed by several replies that never went beyond 3.3 degrees. Due to the earthquake, electricity supplying was affected in several localities of Galati County. The ambulance services in Vrancea received numerous phone calls reporting panic attacks and the functioning of mobile telephony services was temporarily affected.
Also, in Vrancea, on October 6, 2013, there was an earthquake of 5.5 degrees on the Richter scale, acknowledged at that time as the strongest for the last four years.
World Earthquakes estimates that the year 2015 will be difficult for Romania
The World Earthquakes organization, which releases predictions based on statistic data regarding earthquakes, has announced that they expect an earthquake ranging over 6.5 degrees to occur in Romania during 2013 – 2017, and the critical year is more likely to be 2015, according to descopera.ro.
Experts of World Earthquakes declared that the accurate prediction of the moment, location and range of an earthquake is impossible due to present limits of technology and explained that their predictions are based on statistical databases (considering all the earthquakes that occurred and occur in various countries) with the help of very complex mathematic algorithms.
Therefore, these are statistical estimations regarding the likelihood of massive earthquakes, which is why the organization advises caution in the interpretation of the predictions, even if the used algorithms are internationally acknowledged for their precision.
According to these estimations, there is a significant likelihood that an earthquake over 6.5 degrees could occur in Romania during 2013 – 2017. 2015 was declared “critical year”.
