Background
Sinarka has a complex structure: A small, 2-km-wide depression open to the NW has been largely filled and overtopped by an andesitic postglacial central cone that itself contains a lava dome that forms the 934 m high point of the island. Another lava dome, Zheltokamennaya Mountain, lies 1.5 km to the SW along the buried SW rim of the caldera, and a smaller dome lies along the northern caldera rim.(Source: GVP)

Remark:
Our list of volcanic eruptions closely follows the database of eruptions of the Smithsonian's Global Volcanism Project (GVP), the internationally most recognized data source for volcanic eruptions, but also includes significant eruptive episodes or related volcano events. "Volcanic eruptions" are usually to be understood as sequences of individual eruptive episodes that can follow each other, or even overlap (if several vents are involved), and can last many years, decades or even longer. For example, the current activity of Stromboli volcano is understood as a single eruption that has been ongoing since 1934.

Sinarka Volcano FAQ
+When was the last eruption of Sinarka volcano?
The last confirmed eruption of Sinarka occurred during 1872 - 1878.
+How often does Sinarka volcano erupt?
Since 1725, Sinarka volcano has had at least 4 historically documented eruptions. This means that it erupts on average every 75 years.
Many eruptions of Sinarka have lasted more than one year. In total, the volcano has been in eruption during 10 out of 300 years until now. In other words, Sinarka has been active at least one in 30 years on average. Note that this value is likely an underestimate, because the known history of eruptions from Sinarka is likely incomplete, especially further back in time.
+When was the largest eruption of Sinarka volcano?
The largest eruption of Sinarka volcano in historic times occurred during 1872 - 1878. It ranks as a sub-plinian eruption with a magnitude 4 on the VEI (Volcanic Explosivity Index) scale.
