Veer

Kerucut piroklastik · Russia · 520 m

Flow ridges are visible on the surface of a sparsely vegetated lava flow originating from the Veer scoria cone to the right, in the Levaya Avacha river valley. Veer is one of a number of cones scattered throughout the Avacha river basin. This eruption took place 1,600-1,700 years Before Present (BP).

Ringkasan geologi

Cinder cones along the Levaya Avacha River about 60 km N of Petropavlovsk-Kamchatskiy erupted lavas over young river terraces. The basaltic Veer cone, located on the W side of the river, produced a lava flow with prominent ridges that descended into the valley. Although Krijanovsky (1934) listed an 1856 eruption, stratigraphic studies have shown that the eruption occurred sometime between the 1,500 years before present (BP) eruption from Barany Amphitheater of Opala volcano and a 1,630 BP eruption from Avachinsky (Dirksen, 1999 pers. comm.). Nearby andesitic Pravy volcano is also of postglacial age.
