Thanks to the dendrochronological and glaciological investigations it has been identified the sequence of cooler and wetter climatic events from the 4-1 millenniums B.C., which has been caused by volcanic eruptions. This paper is a trial of binding one of those events (from 1159-1141 B.C.) with the data observed in the archeological record. The remarkable changes in the cultural image can be observed in the different regions of Central and Southeastern Europe, in the same period (phase HA, or eventual LBA III in the Carpathian Basin). In some of the regions it has come to the complete vanishing of settlement. The spreading of some particular ceramic stylistics streams allows us to reconstruct probable directions of people groups migrations during this event.
