Milna volcano is the southernmost active volcano on Simushir Island, Kurile Islands. It is located immediately SE of the truncated remnant (somma) of Goiaschaia volcano's old cone.
Milna volcano has a 3 km wide caldera breached to the south and steep flanks with deep erosion gullies. In the ice age, the caldera contained a glacier. A young cone with an andesitic dome was built inside the caldera during the past 10,000 years and now forms the highest point of the island. Lava flows of unknown age from this vent have reached the sea in 4-5 km distance.

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.
