Rare earth geochemistry of Arenig cherts from the Ballantrae Ophiolite and Leadhills Imbricate Zone, southern Scotland: implications for origin and significance to the Caledonian Orongeny [PDF]

open access: yes, 1999
Rare earth element (REE) data from low to mid-Arenig cherts are used to test competing models for the early Ordovician evolution of the Laurentian margin in the northern British Isles.

Mechanical and hydraulic properties of Nankai accretionary prism sediments: Effect of stress path [PDF]

open access: yes, 2012
We have conducted triaxial deformation experiments along different loading paths on prism sediments from the Nankai Trough. Different load paths of isotropic loading, uniaxial strain loading, triaxial compression (at constant confining pressure, Pc ...

Assessing the Risk of Potential Tsunamigenic Earthquakes in the Mentawai Region by Seismic Imaging, Central Sumatra

open access: yesGeochemistry, Geophysics, Geosystems
In the marginal regions along subduction zones, oceanic plates subducting beneath continental plates produce the largest number of earthquakes on Earth and sometimes devastating tsunamis.

TSUNAMIGENIC SOURCE MECHANISM AND EFFICIENCY OF THE MARCH 11, 2011 SANRIKU EARTHQUAKE IN JAPAN [PDF]

open access: yesScience of Tsunami Hazards, 2011
The great Tohoku earthquake of March 11, 2011 generated a very destructive and anomalously high tsunami. To understand its source mechanism, an examination was undertaken of the seismotectonics of the region and of the earthquake’ focal mechanism, energy

Seismic studies of the northern Cascadia accretionary prism: sediment consolidation and gas hydrates [PDF]

open access: yes, 2018
This thesis work was directed at aspects of two related problems: (1) sediment compaction and fluid expulsion processes in a subduction margin accretionary prism, and (2) the nature and concentration of gas hydrates that form bottom-simulating ...

Mud volcanism and fluid seepage at Venere mud volcano in the Calabrian Accretionary Prism (Central Mediterranean) [PDF]

open access: yes, 2017
Cold seeps are the natural expression of the release of gases, liquids, solids, or a combination of components, which are sourced from subsurface sediments and are emitted at temperatures comparable to surface values.

80 Years of research on tsunamigenic earthquakes in the Makran subduction zone (1945–2025): a review- Part A: MSZ features

open access: yesFrontiers in Earth Science
The Makran Subduction Zone (MSZ) gained wide interest following the 1945 tsunamigenic earthquake. This three-part (A, B, and C) review provides a comprehensive and multidisciplinary synthesis of 80 years of research on tsunamigenic earthquakes associated

Seafloor structural observations, Costa Rica accretionary prism [PDF]

open access: yes, 1996
By studying seafloor morphology we can make associations between near surface defornation, fluid flow and the overakk structural framework of accretionary prisms.

Sediment microstructures and deformation at the toe of the Nankai accretionary prism: Effects of accretion and diagenesis, and evolution of the decollement [PDF]

open access: yes, 2004
Sediments incorporated into accretionary prisms experience significant changes in physical properties, grain fabric, and diagenesis. The record of such changes is preserved in sediment microstructures.
