|The truncated andesitic cone is of Holocene age and rises to a height of 761 m. The walls of the 750-m-wide breached summit crater extend to the southern coast. Two lava domes were constructed near the headwall of the breached crater. No historical eruptions are known from Shirinki, but the summit domes are very young and possibly formed in historical time [Gorshkov, 1970].
