Seismic experiment spreads across Poland

The Trans-European Suite Zone (TESZ), is probably the most important geologic boundary in Europe, north of the Alpine orogenic belt. The TESZ bounds the western edge of the Precambrian East European Craton, which forms a platform in eastern Poland and is the product of complex plate convergence that led to the formation of Pangea and thus continental Europe as we know it today. In Poland, a large seismic experiment was conducted in May of 1997 to target the deep structure of the TESZ and the complex series of upper crustal features associated with it. The experiment is perhaps the largest entirely land-based lithospheric seismic experiment ever under-taken with about 600 instruments deployed to record 63 shots along five profiles with a combined length of about 2000 km.
