New Results of High Resolution Seismic Measurements at Lake Balaton

Investigations of Lake Balaton by the Geological Institute of Hungary started in 1981. Between 1987 and 1989 within the framework of Cuban–Hungarian cooperation a total of 373 km boomer seismic section was registered covering the entire lake in a quasi uniform network. As a result of the profiles’ evaluation a picture was drown up about the spatial distribution of lacustrine sediments, the mud structure as well as the variable morphology and geological setting, till 30 m depth from the lake bottom. During 2003 and 2004, in the cooperation of Geophysical and Geological Institutes the original thermo-paper records were digitally archived, re-evaluated and the recent records were integrated as well. The re-evaluation gave the opportunity for a more detailed spatial determination of the geological structure of the bed (layers, faults). This gave an opportunity to plan the research of Pleistocene sediments, deposited before the lake formation.
