A Confidence-Based Assessment Method for Distinguishing Pyroclastic Density Current Deposits From Other Volcaniclastic Units

open access: yesFrontiers in Earth Science, 2020
Pyroclastic density currents (PDCs) are a destructive volcanic hazard. Quantifying the types, frequency and magnitudes of PDC events is essential for effective risk management, but since historical records at best extend a few hundred years this usually ...

IMEX_SfloW2D 1.0: a depth-averaged numerical flow model for pyroclastic avalanches [PDF]

open access: yesGeoscientific Model Development, 2019
Pyroclastic avalanches are a type of granular flow generated at active volcanoes by different mechanisms, including the collapse of steep pyroclastic deposits (e.g., scoria and ash cones), fountaining during moderately explosive eruptions, and crumbling ...

Analysis of Optical Satellite Images and Pyroclastic Flow Inundation Model for Monitoring of Pyroclastic Flow Deposit Area [PDF]

open access: yesKorean Journal of Remote Sensing, 2014
Field survey research on damages caused by volcanic activities has plenty of difficulties due to human resources, safety and costs issues. Remote sensing application using satellite image is one of very useful tools to overcome those issues. In this study, we monitored the volcanic activities of Sinabung volcano in 2010, which is located in Sumatra ...

Dynamics of pyroclastic density currents : : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Earth Sciences at Massey University, Palmerston North, New Zealand [PDF]

open access: yes, 2016
Listed in 2016 Dean's List of Exceptional ThesesPyroclastic density currents (PDCs) are the most dangerous mass flows on Earth. Yet they remain poorly understood because internal measurements and observations are hitherto non-existent.

Rifting and arc-related early Paleozoic volcanism along the North Gondwana margin: geochemical and geological evidence from Sardinia (Italy) [PDF]

open access: yes, 2012
Three series of volcanic rocks accumulated during the Cambrian to Silurian in the metasediment-dominated Variscan basement of Sardinia. They provide a record of the changing geodynamic setting of the North Gondwana margin between Upper Cambrian and ...

Floristic Composition of Groundcover Vegetation after the 2010 Pyroclastic Fire on Mount Merapi

open access: yesJurnal Manajemen Hutan Tropika, 2013
Mount Merapi with its Merapi-type pyroclastic flows provides burnt and unburnt areas which are excellent to study establishment events of pioneer plant species. Using site comparison approach, floristic composition was studied, and thus an area that was

Landslides in sensitive soils, Tauranga, New Zealand. [PDF]

open access: yes, 2013
In the Tauranga region sensitive soil failures commonly occur after heavy rainfall events, causing considerable infrastructure damage. Several notable landslides include a large failure at Bramley Drive, Omokoroa in 1979, the Ruahihi Canal collapse in ...
