Abstract
From earthquakes that occurred between 1763 and 1964 in the Pannonian Basin, maps were prepared by means of a computer. These maps show the epicentral density, the magnitude density and the densities of the epicentral intensities and of the seismic energy in form of isolines. In the energy map, individual events are overemphasized. The other seismic maps show a close relationship with tectonics.A low temperature at a depth of 1 km is very closely correlated with an increased occurence of earthquakes: a main chain of anomalies extends along the Transdanubian Central Range up to the Bükk Mountains. It is intersected by a chain Komárom-Esztergom-Budapest-Kecskemét-Hódmezövásárhely. Induvidual anomalies are found at the mouth of the Mura river near Pecs. Two tectonic hypotheses on the formation of the Pannonian Basin are dicussed.
