Basal Force Probability Distributions in Thin‐Layer Granular Flows

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 8, August 2026.
Abstract Extreme geophysical flows, such as granular and debris flows, can significantly shape the landscape in steep lands and generate seismic signals that can be recorded over long distances. However, direct field measurements needed to constrain the granular physics remain difficult due to the damage potential of those flows.

Hybrid turbidite–contourite systems in the modern Tarakan Basin: seismic sedimentology and analogue for subsurface storage

Frontiers in Earth Science
Hybrid turbidite–contourite systems are present where gravity-driven and bottom-current processes interact. Although recent studies have advanced our understanding, deciphering the relative roles of downslope and alongslope processes in shaping the deep ...

A review of the supercritical state of eruption‐fed volcanic density currents in subaerial and subaqueous settings

Sedimentology, Volume 73, Issue 5, Page 1331-1351, August 2026.
ABSTRACT Subaerial Pyroclastic Density Currents (PDCs) and Subaqueous Eruption‐Fed Density Currents (SEFDCs) produced during volcanic eruptions can present major hazards to surrounding communities and ecosystems. The bedforms deposited by these volcanic density currents can provide insights into the nature of transport and depositional processes, which

The Seismic Expression of Core Complex‐Style Extensional Detachment Faults in Rifted Margins

Terra Nova, Volume 38, Issue 4, Page 251-258, August 2026.
ABSTRACT The identification of core complex‐style extensional detachment faults (CCDFs) in rifted margins is crucial for accurately restoring their stratigraphic and thermal histories. Yet recognising CCDFs in seismic reflection images is challenging due to their faint topographic expression; the lack of associated abrupt offset in seismic reflections;
