Ruruidake [Smirnov]
About Ruruidake [Smirnov]
Ruruidake is a late Pleistocene andesitic-to-dacitic volcanic complex on the NW tip of Kunashir Island in the southern Kuriles, NW of Chachadake [Tiatia} volcano. About 2.5 km SSW of the Ruruidake peak, the gently sloping Smirnov edifice partially retains a constructional form, but the southern side has been heavily eroded by glaciers, exposing its Tertiary basement. A wide glacial trough on the SE flank of Smirnov contains a pyroclastic cone at its head that fed a 4 km lava flow. Another pyroclastic cone is located at the base of the trough near the terminus of the lava flow. Two fresh-looking lava domes of Holocene age also lie within the glacial valley to the north.
