IL LANGHIANO-SERRAVALLIANO TRA LE VALLI DEL TANARO E DEL BELBO. CONFRONTI CON I DINTORNI DI GAVI E DI FINALE LIGURE

open access: yesRivista Italiana di Paleontologia e Stratigrafia, 2018
The Langhian-Serravallian sequences cropping out in the southwestern part of the Tertiary Piedmont Basin (NW Italy) are firstly examined. Secondly, comparisons are stated with coeval sequences cropping out in the Gavi region (easternmost Tertiary Piedmont

Repeated occurrence of surface-sediment remobilization along the landward slope of the Japan Trench by great earthquakes

open access: yesEarth, Planets and Space, 2020
Deep-sea turbidites have been utilized to understand the history of past large earthquakes. Surface-sediment remobilization is considered to be a mechanism for the initiation of earthquake-induced turbidity currents, based on the studies on the event ...

Confirmation of the impact origin of the Late Ordovician Tvären impact structure (southeast Sweden) and emplacement of impactites in a marine setting

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract The Tvären structure in southeastern Sweden has been listed as a confirmed marine‐target impact structure for decades. However, to date, no measurements and/or indexed data of planar deformation features in quartz grains from the structure have been published or any other unequivocal evidence of impact.

Heterogeneous Sediment Input at the Nankai Trough Subduction Zone: Implications for Shallow Slow Earthquake Localization

open access: yesGeochemistry, Geophysics, Geosystems, 2021
Subducted sediment plays a key role in modulating pore pressure and seismic behavior at subduction zones. We investigated the seismic character of incoming sediments to test how sediment and basement variations relate to the along‐strike changes within ...

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

open access: yesSedimentology, EarlyView.
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

Submarine Paleoseismology Along Populated Transform Boundaries: The Enriquillo-Plantain-Garden Fault, Canal du Sud, Haiti, and the North Anatolian Fault, Marmara Sea, Turkey [PDF]

open access: yesOceanography, 2014
Continental transform boundaries cross heavily populated regions and are associated with destructive earthquakes worldwide. The devastating 1999 Turkey earthquakes and the offshore 2010 Haiti earthquake emphasized the urgent need to study the submerged ...

The Western Irish Namurian Basin reassessed [PDF]

open access: yes, 2000
Current basin models for the Western Irish Namurian Basin (WINB) envisage an elongate trough along the line of the present-day Shannon Estuary that was infilled with clastic sediments derived from a hinterland that lay to the W or NW.
