“…The basin formed at the intersection of the Eger Rift ( Kopecký, 1979 ) and the Regensburg–Leipzig–Rostock fault zone ( Bankwitz et al, 2003b ; Geissler et al, 2004 ) where four Quaternary volcanoes existed ( Mrlina et al, 2009 ; Rohrmüller et al, 2018 ). The western Eger Rift has been well studied regarding structure of the lithosphere, seismic activity, sedimentology, and fault characteristics ( Dobeš et al, 1986 ; Bucha, et al, 1990 ; Špičáková et al, 2000 ; Bankwitz et al, 2003a ; Kämpf et al, 2005 , 2007 , 2013 ; Flechsig et al, 2008 ; Fischer et al, 2014 ; Nickschick et al, 2015 ; Bussert et al, 2017 ). The seismic activity in this area occurs as “earthquake swarms,” which are typically numerous small earthquakes at upper crustal depths that cluster in time and space ( Fischer et al, 2014 ).…”
