Kinenin

Maar · Russia · 583 m

Kinenin maar is seen in this near-vertical aerial photo, with the lake reaching 1 km in diameter. The maar was named after the Kinenin River seen to the south, and was formed during an explosive eruption about 1,100 years ago. The NE crater wall is significantly higher and coincides with the dominant direction of the tephra dispersal.

Resumen geológico

Kinenin maar lies at the eastern foot of the Sredinny Range, about 80 km NNW of Sheveluch volcano. The 2.5-km-wide, funnel-shaped maar was formed along the Kinenin River, a tributary of the Elovka. It is partially filled by a 1-km-wide lake whose surface is at 400 m elevation. The eastern rim at about 580 m is the high point of the crater. The eruption of Kinenin took place about 1,100 years ago, making it the youngest known maar in Kamchatka. Both silicic pyroclastic flows and mafic pyroclastic ejecta were produced, which were distributed primarily to the ENE. The location is north of the active Kamchatka subduction zone.
