Its coasts are generally rocky or pebbled, but there are also a few sandy beaches. The volcano is currently active (but not erupting), and fumaroles are found at the craters. The latest eruptive activity was a steam explosion in 1888. A great depression, Rammos and Lakki, is located east of the center of the island. It is steep sided and its bottom is about 100m above sea level. At the far end of the valley is a small explosion sink named Stefanos (in the postcard), with about 300m in diameter and 25 m deep.
