Tri Sestry
"Tri Sestry, located on the shore of the Sea of Okhotsk in central Urup Island, is an eroded andesitic stratovolcano whose flanks are cut by deep ravines. A summit lava dome on Tri Sestry ("Three Sisters") was active during either the late Pleistocene or early Holocene (Gorshkov, 1970). Hot springs along the coast mark its latest activity."  -Smithsonian Volcano Archive
