Dynamical weakening of pyroclastic flows by mechanical vibrations [PDF]
EPJ Web of Conferences, 2017 Dynamical weakening of dense granular flows plays a critical role on diverse geological events such as seismic faulting and landslides. A common feature of these processes is the development of fluid-solid relative flows that could lead to fluidization ...

Permian Large Igneous Provinces and Their Paleoenvironmental Effects
Geophysical Monograph Series, Page 417-434., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Fluidization in pyroclastic flows
Powder TechnologyPyroclastic flows are mixtures of gas and particles generated by gravitational collapse of lava domes or fall-back of eruption columns during explosive eruptions. They are major natural hazards because they can propagate far away from the source at speeds that largely exceed those of most natural or anthropogenic granular flows.

Pyroclastic deposits and volcanic history of Mayor Island [PDF]
, 1981 The emergent summit of Mayor Island, Bay of Plenty, New Zealand, is a peralkaline rhyolite volcano constructed by: a sequence of lava flows, the Tutaretare Rhyolite Formation(new); and pyroclastic deposits, the Oira Pyroclastite Formation (new).

Experimental study of dense pyroclastic density currents using sustained, gas-fluidized granular flows [PDF]
, 2014 International audienceWe present the results of laboratory experiments on the behaviour of sustained, dense granular flows in a horizontal flume, in which high-gas pore pressure was maintained throughout the flow duration by continuous injection of gas ...
