Characteristics of Pyroclastic Flow at Sakurajima Volcano's Showa Crater [PDF]

, 2018
Eruptions at the Showa crater become active since 2008 and are sometimes accompanied with small pyroclastic flows. It is important to understand the mechanism of generation of the pyroclastic flow for volcanic disaster prevention.

Pyroclastic flows related to the collapse of trachytic domes in the Middle Miocene Volcanic Edifice of Jandía (Fuerteventura, Canary Islands)

, 2021
El sector oriental del Edificio Volcánico Mioceno Medio de Jandía está constituido, esencialmente, por una serie de domos sálicos y materiales piroclásticos separados por aglomerados basálticos que marcan importantes eventos de erosión y detención de ...

Fluidization and attrition of pyroclastic granular solids.

, 2004
Pyroclastic flows have been frequently addressed in the recent volcanological literature as far as the depositional mechanisms and the field features of the related deposits are concerned.

Computer simulations of pyroclastic flows from dome collapse

, 1998
We present a method of simulating both the avalanche and surge components of pyroclastic flows generated by lava collapsing from a growing Pelean dome.

Large‐Scale Topographic Changes at Erupting Volcanoes Measured by the TanDEM‐X Digital Change Map

Earth and Space Science
Volcanic eruptions cause large‐scale topographic changes, through the emplacement of lava flows and lava domes, the formation of craters and calderas, and thick ash and pyroclastic deposits.

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 entrance of pyroclastic flows into the sea, II. theoretical considerations on subaqueous emplacement and welding

, 1980
Theoretical models of debris flow emplacement suggest that some types of pyroclastic flow can move into and maintain their integrity underwater. These subaqueous flows can be emplaced at high temperature, cooling only tens of degrees centigrade.

Application of dimensional analysis technique to grading processes in pyroclastic flows

, 1996
The dimensional analysis technique is applied to specific aspects of pyroclastic flow transport and deposition, and particularly to the grading processes of lithic and pumice clasts in moving pyroclastic flows.

Paleomagnetic evidence for high‐temperature emplacement of the 1883 subaqueous pyroclastic flows from Krakatau Volcano, Indonesia

, 1994
The paroxysmal 1883 eruption of Krakatau volcano in Indonesia discharged at least 6.5 km3 (dense rock equivalent) of pyroclastic material into the shallow waters of the Sunda Straits within a 15 km radius of the volcano.
