The main features are 2 large domes called Tsurumi (1374 m) and Yufu (1584 m) on the east and west end of the complex. Only a single eruption, from Tsurumi in 867 AD, is known in historical time. The colorful hot spring pools and mudpots of Beppu along the coast form one of Japan's most noted thermal areas. Introduction:3 smaller lava domes are located on the north flank of the Tsurumi dome. The latest activity at both the andesitic-to-dacitic Tsurumi and Yufu groups postdates the 6300-years-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 2200 years ago from Yufu-dake volcano began with collapse of the northern flank that produced a debris avalanche and was followed by lava dome growth and associated pyroclastic flows. --- Source: Smithsonian / GVP volcano information |
