BackgroundThe Aluchin volcanoes belong to an intraplate hot-spot volcanic province in Siberia which also comprise several volcanoes including the beautiful extinct Anyuy volcano.
The younger Aluchin group contains 4 young cinder cones, which were named Alpha-1, Alpha-2, Beta and Gamma.
Alpha-1 and -2 at the western foot of Alpha-1 are in the Bolotnaya river valley, 1.5. km west of Aluchin river. Alpha-1 is a 70 m high and over 800 m wide cone, and has a crater which is 580 m wide and 25 m deep.
Beta is in the Aluchin river valley 5 km SE of the Alpha-1 and -2 group. It is a 50 m high and 740 m wide cone and has a 200-270 m crater.
Gamma is 1.3 km SW of Beta and is a 40 m high and 440 m wide cone with a 90 m wide crater.
A 2-8 km wide basaltic lava flow north of Beta and Gamma extends over 85 km length.
