Chikurachki

성층화산 · Russia · 1781m

The NW slopes of Chikurachki, the highest volcano on Paramushir Island, rises above the Sea of Okhotsk. Oxidized scoria covering the upper part of the cone result in the distinctive red color. The Tatarinov group of six volcanic centers is located immediately to the south of Chikurachki, forming the ridge to the right. In contrast to the frequently active Chikurachki, the Tatarinov volcanoes are extensively eroded and have a more complex structure.

Chikurachki, the highest volcano on Paramushir Island in the northern Kuriles, is a relatively small cone constructed on a high Pleistocene edifice. Oxidized basaltic-to-andesitic scoria deposits covering the upper part of the cone give it a distinctive red color. Frequent basaltic Plinian eruptions have occurred during the Holocene. Lava flows have reached the sea and formed capes on the NW coast; several young lava flows are also present on the E flank beneath a scoria deposit. The Tatarinov group of six volcanic centers is located immediately to the south, and the Lomonosov cinder cone group, the source of an early Holocene lava flow that reached the saddle between it and Fuss Peak to the west, lies at the southern end of the N-S-trending Chikurachki-Tatarinov complex. The Tatarinov centers are extensively modified by erosion and have a more complex structure. Tephrochronology gives evidence of an eruption around 1690 CE from Tatarinov, although its southern cone contains a sulfur-encrusted crater with fumaroles that were active along the margin of a crater lake until 1959.

영어 요약

Chikurachki is the highest volcano on Paramushir Island in the northern Kuril Islands. It is actually a relatively small volcanic cone constructed on a high Pleistocene volcanic edifice. Oxidized andesitic scoria deposits covering the upper part of the young cone give it a distinctive red color. Lava flows from the 1,816-metre (5,958 ft) high Chikurachki reached the sea and formed capes on the northwest coast; several young lava flows also emerge from beneath the scoria blanket on the eastern flank.
