Summary The investigated region covers the territories of Bulgaria, Czechoslovakia, the G.D.R., Hungary, Moldavia, Poland, Romania and the south-western Ukraine and parts of Austria, Greece, and Yugoslavia. Maps of epicentres demonstrate the geographical distribution of activity. Earthquakes occur in several seismogenic belts (provinces) related to neotectonic features of the region. A special phenomenon is the intermediate-depth focus of Vrancea releasing in the region the largest amounts of energy, together with a few crustal foci in Bulgaria.
