Recent Known Eruption: Undated, but probable Holocene eruption
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].

Potencial Hazard
Ash clouds, ash falls, pyroclastic flows, hot avalanches and lahars are a potential hazard associated with explosive eruptions of this volcano. The volcano poses a potential hazard to international and local airlines passing in the Kuriles region, since the height of its ash emissions can reach 10-15 km above sea level, ash plumes and clouds can drift hundreds and thousands of kilometers from the volcano in different directions.
