Debris Flow and Pyroclastic Flow at Unzen Volcano
JAPANESE JOURNAL OF MULTIPHASE FLOW, 1993 Unzen Volcano began to erupt in November 1990 after 198 years of dormancy and has remained active. Continuous growth of a lava dome and falls of lava rocks have resulted in frequent pyroclastic flows. Since a great volume of volcanic material has been deposited and scattered by the pyroclastic flows, debris flows have frequently occurred along the ...

The fluidization behaviour of ignimbrite at high temperature and with mechanical agitation [PDF]
, 2004 Experiments were carried out to study the fluidization behaviour of ignimbrite at high temperature and while being mechanically agitated. Geldart group C behaviour occurs up to 565 degreesC when the material is subjected to increasing gas flow ( without ...

Eruptive Stratigraphy And The Transport And Deposition Of Pyroclastic Material From The Caldera-Forming Eruption Of Volcan Ceboruco, Nayarit, Mexico [PDF]
, 2001 Thesis (M.S.) University of Alaska Fairbanks, 2001The ~1000 A.D. eruption of Volcan Ceboruco produced 3--4 km3 of rhyodacitic to dacitic magma erupted as the Jala Pumice, forming a 3.7-km-wide caldera.
