Late Quaternary marine terraces are well-developed around the Yelizavety Cape, in northern Sakhalin. There are two levels of Pleistocene terraces (H and M surfaces) and four levels of Holocene terraces (F and L1-3 surfaces). The M surface is either an abrasion platform covered by talus deposits several ten meters thick, or constructional surface of littoral sand and gravel overlain by periglacial deposits less than two meters thick. These observations strongly indicate that the M surface was formed in the Last Interglacial age. The height of the M surface is 11 to 24 m above sea level, so that the average uplift rate since the Last Interglacial age is estimated to 0.1 to 0.2 mm/yr. The Tua fault to the west of the Yelizavety Cape has been inactive during the Late Quaternary, because of the scarcity of tectonic geomorphologic features along the fault. The formation age and the height of the M surface indicate that during the Late Quaternary, the uplift rate around the Yelizavety Cape is comparable with that along the eastern coast of south Sakhalin. The L surfaces are composed of storm-ridge deposits, in which well-sorted sands and granules are intercalated with peaty layers. The landward limit of the backshore of the Li Surface is 5.5 to 7.2 mabove sea level. The L1 surface was formed at Subatlantic Period (1600-520 14C yrBP).
