Chirip volcanChirip volcano is a twin volcano forming the Chirip peninsula which streches NW into the Okhotsk Sea from central Iturup Island, Kurile Island, 230 km north of Hokkaido, Japan.
The 2 stratovolcanoes are Chirip volcano in the N and Bogdan Khmelnitskii to the S. They overly an older volcanic edifice. The lavas erupted from both volcanoes are dominantly basaltic, which is unusual for subduction zone volcanoes.
Only 2 historic eruptions are known. The last eruption in 1860 occurred from a vent SE of the summit of Bogdan Khmelnitskii volcano.
Introduction:Lava flows from Chirip and Bogdan Khmelnitskii volcanoes are cut by a large, 4-km-wide depression on the west side.
Chirip volcano has a shallow summit crater, partially filled by a small lake, that has fed lava flows down all sides. Flank cones are located on the northern flank of Chirip.
Lava flows from Bogdan Khmelnitskii (also known as Minami-Chirippu or South Chirippu) reach the coast on both the east and west sides.
