It can be divided into five areas, the biggest being the Eastern Alps, which constitute 62% of the nation's total area. The Austrian foothills at the base of the Alps and the Carpathians account for around 12% and the foothills in the east and areas surrounding the periphery of the Pannoni low country amount to about 12% of the total landmass. The second greater mountain area (much lower than the Alps) is situated in the north. Known as the Austrian granite plateau, it is located in the central area of the Bohemian Mass and accounts for 10% of Austria. The Austrian portion of the Vienna basin makes up the remaining 4%.
