| The gently sloping, 1220-m-high Berutarube stratovolcano forms the SW tip of Iturup Island. The flanks of the andesitic-to-dacitic volcano are deeply dissected by wide glacial valleys; a low saddle on the NE side separates Berutarube from the slopes of Lvinaya Past caldera. The only known Holocene activity at Berutarube produced a small pyroclastic cone that was superposed on the intersecting headwalls of U-shaped valleys and cirques on the volcano's broad eroded summit. The hydrothermally altered summit cone was the source of two small lava flows. Berutarube was estimated to have ceased erupting only a few hundred to at most 1000 years ago (Gorshkov, 1970). No confirmed historical eruptions of Berutarube are known, although fumarolic areas on the walls of the summit crater are currently depositing sulfur. | |||
