An amount of upheaval and its horizontal distribution were measured using topographic maps, aerial photographs, data of levelling and so on. Since 1952, the general increase in the upheaval rate was found, and in some places, its rate exceeded ca. 30 cm/year. Recently, the upheaval rate decreased, and in some place, subsidence was found.
