Details for: Chachadake [Tiatia]
The SE flanks of 1819-m-high Tiatia volcano, one of the most impressive of the Kuril Islands, rise above the Pacific Ocean at the NE tip of Kunashir Island. A beautifully symmetrical cone (center) rises above the low snow-covered rim of an erosionally furrowed, 2.1 x 2.4 km caldera. A major explosive eruption in 1973 was the first since Tiatia's initial historical eruption in 1812.
