Earth planets space, 58, 583–593, 2006 vulcanian eruptions with dominant single force components observed during the asama 2004 volcanic activity in japan... The source depths of the single force are shallower than 200 m from the bottom of the summit crater, and the order of magnitude of the single force is 1010–1011N....
238u-230th-226ra-210pb-210po, 232th-228ra, and 235u-231pa constraints on the ages and petrogenesis of vailulu’u and... Maximum eruption ages based on the presence of parent-daughter disequilibria indicate that Vailulu’u is magmatically productive with young lavas (<8 Ka) resurfacing both its summit crater and lower flanks....
Ground deformation sources preceding increase in eruptive activity of sakurajima volcano -minamidake crater in 1999 and showa crater in 2006-We analyzed GPS data during 1998-2006 to make clear process of magma accumulation and movement of Sakurajima volcano prior to eruptive activity at the summit crater in 1999 and eruptive activity at Showa crater resumed in 2006....
Earth planets space, 54, 217–229, 2002 volcanic-related alteration and geochemistry of iwodake volcano,... Inside the summit crater of about 300 m diameter and 50 m depth, volcanic gas with maximum temperature>800◦C is discharged....
