Abstract:
For seismically active regions of the world, earthquakes are an integral part of the environment (nature) and there is no area of the Earth that is not affected (to a certain degree) by this natural phenomenon. Earthquakes are the expression of the continuing evolution of the Earth planet. The territory of Bulgaria (situated in the eastern part of the Balkan Peninsula) represents a typical example of high seismic risk area. Bulgaria is located, from seismological point of view, in the Alpo-Himalayan seismic belt, which is characterized by high seismic activity. Over the past centuries, Bulgaria has experienced strong earthquakes. Some of the Europe¢s strongest earthquakes occurred in Bulgaria at the beginning of the 20th century (from 1901 to 1928). No such large earthquakes occurred in Bulgaria since 1928. In the present study, the six strongest earthquakes occurred in Bulgaria after 1900 are presented.
