The literature on the structure and behaviour of gravity currents is reviewed, with emphasis
on some recent studies, and with particular attention to turbidity currents, though reference is …

Pyroclastic density currents (PDCs) are dangerous multiphase flows originating from
volcanic eruptions. PDCs cause more than a third of volcanic fatalities globally and …

Submarine sediment density flows are one of the most important processes for moving
sediment across our planet, yet they are extremely difficult to monitor directly. The speed of …

Ignimbrites are vast, landscape-modifying deposits composed mainly of pumice fragments
and ash. They derive from the most. hazardous types of explosive volcanic eruptions and …

The origin of massive sands in turbidite successions has commonly been attributed to the
rapid dum** of sand due to flow unsteadiness in collapsing, single surge‐type, high …

Over the past 25 years, our understanding of the physical processes that drive volcanic
eruptions has increased enormously thanks to major advances in computational and …

The simple physical models which are popularly used to describe deposition from turbidity
currents are based on the notion of unidirectional waning flow, resulting in the familiar …

We propose a mechanism by which massive ignimbrite and layered ignimbrite sequences—
the latter liable to have been previously interpreted as multiple flow units-form by …

High-speed, gravity-driven flows of hot particles and gas are a common and highly
destructive product of explosive volcanism. They range widely in nature from expanded …
