Resumen geológico

The 3-km-diameter island of Shirinki is located west of the main Kuril Island arc and ~20 km WSW of Fuss Peak on Paramushir Island. The truncated andesitic cone has a 750-m-wide breached summit crater with multiple peaks around the rim and two lava domes near the headwall of the breached crater. No eruptions have been documented, but the summit domes were considered to be very young by Gorshkov (1970). The remnants of an older edifice on the eastern side of the island are mostly covered by pumiceous pyroclastic-fall deposits.
