Geological Summary: (Note this is same source from Yufuin as well). A group of lava domes rises above the hot spring resort city of Beppu on Japan's Inland Sea, possibly within an ancient breached caldera. Two large lava domes, Tsurumidake and Yufudake (the highest at 1,584 m), are located at the east and west sides of the complex, respectively. Three smaller lava domes are on the N flank of Tsurumidake, including Garandake. The latest activity at both the andesitic-to-dacitic Tsurumi and Yufu groups postdates the 6,300-year-old Akahoya ash from Kikai volcano. Pyroclastic flows dominated during older eruptions, whereas lava domes and lava flows are most common in more recent eruptions. An eruption about 2,200 years ago from Yufudake began with collapse of the N flank that produced a debris avalanche and was followed by lava dome growth and associated pyroclastic flows. The most recent known eruption was from Tsurumi in 867 CE, when there was explosive activity from the summit area. The colorful hot spring pools and mudpots of Beppu along the coast are a noted thermal area. (Source - Smithsonian Global Volcanism Program)
