Abstract
Uplifted Pleistocene marine sediments, submerged ancient ruins and rai sed beaches confirm earlier views that the asymmetry of the relief of Amorgos Island (southern Aegean) testifies to a fault-bounded block up lifted and tilted along a SW-NE trending horizontal axis; the uplifted coast corresponds to a high-gradient slope controlled by an oblique m aster normal fault. Furthermore, geomorphic and biological evidence, r adiometric data and comparison of aerial photographs indicates that th e 1956 earthquake (M(s) = 7.4) uplifted the footwall of this normal fa ult by about 30 cm.
