Abstract

From the earthquakes taking place in the Pannonian Basin from 1763 till 1984, seismic maps were constructed by means of a computer. The maps with lines of equal epicentral density and magnitude density are particularly closely related to the tectonic units of the basin striking WSW-ENE. Maxima in the afore-said seismic maps are linked with minima in the map of the temperature at a depth of 2 km. The distribution of the epicentral and magnitude density maxima also exhibits a relationship with the heat flow minima and, to a somewhat lesser extent, with the maxima of the horizontal geothermal gradient and with the positive regional Bouguer anomalies.
