Yali is the uppermost part of a submerged caldera and is part of the Nisyros volcanic field. The SW part of the 4-5 km island is composed of the Lower and Upper Pumice deposits, and the NE area consists of lave domes, seen in this December 2019 Planet Labs satellite image monthly mosaic (N is at the top). The pumice quarry in the SW exposes pumice deposits in 60-100 m thick sections.
