To the NE, there are several other lava domes which are less than 10,000 years old. Their formation modified the shore of a former lake at the northern side of the caldera to extremely sinuous shape.The forested andesitic Tebenkov volcano is located immediately NE of the Grozny dome complex. Machekh is a crater immediately south of Tebenkov and has strong fumarolic activity.
