- W1636944531 abstract "Preliminary experimental investigations of the fragmentation of dome lava from Unzen volcano, Kyushu Island (Japan), have indicated that fragmentation is influenced by density. Two field campaigns (2000 and 2001) have been conducted to obtain extensive density information on the pyroclastic flow deposits of the 1990 to 1995 eruption. This allows the characterisation of the pre-collapse dome density. Such density data enable us to evaluate the effect and influence of transport processes on the density distribution inside the deposits. Experiments have been performed to determine the fragmentation threshold of hot, pressurised rock cylinders (60 x 26 mm) due to rapid decompression. The cylinders are pressurised using argon gas. The fragmentation bomb simulates the conditions for volcanic fragmentation induced by rapid decompression. At 850 ◦C dense dacite with an open porosity of 3.76 % requires an initial pressure difference of 22.5 MPa to overcome the threshold. The threshold value decreases steeply with increasing porosity. At porosities greater than 12 % the rate of decrease of threshold value is reduced. The results presented here correlate with those obtained from Merapi, Montserrat and Mt. St. Helens (Spieler, 2001). Natural pyroclastics and pyroclastics generated experimentally have been compared using a laser particle size analyzer to correlate our experimental trends with data from natural products." @default.
