Reactivation of minor faults in a blind active fault area: A case study of the aftershock area of the 2000 Western Tottori Earthquake, Japan

open access: yesJournal of Asian Earth Sciences: X, 2021
The 2000 Western Tottori Earthquake (Mw 6.6, Mjma 7.3) in Japan occurred in an area where no active faults are known to exist. We examined the distribution, occurrence, paleostress field, and K–Ar ages of minor faults in the aftershock region of this ...

From Oblique Thrust to Strike-Slip Fault: Progressive Stages of an Accretionary Wedge Development [PDF]

open access: yesLithosphere
Accretionary wedges of orogenic belts develop differently based on the direction of thrusting, which can be perpendicular to oblique to the belt. In the case of oblique thrusting, stress partitioning occurs, which dissects the accretionary wedge, changes

Structural Controls on Shallow Cenozoic Fluid Flow in the Otago Schist, New Zealand

open access: yesGeofluids, 2020
The Otago Schist in the South Island of New Zealand represents an exhumed Mesozoic accretionary prism. Two coastal areas (Akatore Creek and Bruce Rocks) south of Dunedin preserve structural and geochemical evidence for the development of postmetamorphic ...

Parametric and non-parametric statistical approaches to the determination of paleostress from dilatant fractures: Application to an Early Miocene dike swarm in central Japan [PDF]

open access: yes, 2013
Several methods have been proposed for determining paleostress states from orientations of dilatant fractures such as dikes and veins. Recently a stochastic inversion method was invented to objectively estimate the principal stress axes and the stress ...

Reconciling post-orogenic faulting, paleostress evolution, and structural inheritance in the seismogenic northern Apennines (Italy): insights from the Monti Martani Fault System [PDF]

open access: yesSolid Earth
Structural inheritance plays a significant role in the evolution of fault systems in different tectonic settings. Both positive reactivation of pre-orogenic extensional faults and negative reactivation of synorogenic reverse faults during orogenic cycles

Paleo-stress orientations and magnitudes from triaxial testing and stress inversion analysis in Nankai accretionary prism sediments

open access: yesProgress in Earth and Planetary Science, 2019
Combined knowledge on the magnitude as well as the orientation of paleo-stress is usually not given. Based on drilling investigations and laboratory experiments, we are able to provide both, constraints on paleo-stress magnitude as well as orientation in

Mechanism and Prediction of Geothermal Resources Controlled by Neotectonics in Mountainous Areas: A Case Study of Southeastern Zhangjiakou City, China

open access: yesFrontiers in Earth Science, 2022
The geothermal resources in mountainous areas are usually controlled by neotectonic faults. To minimize the risk in site selection for geothermal drilling, the controlling mechanism must be identified.

Seismotectonic analysis around the Mont Terri rock laboratory (Switzerland): a pilot study [PDF]

open access: yes, 2017
For this pilot study we used recorded seismic events from the SED permanent network and data from a dedicated SNS network to improve the seismotectonic understanding of very weak seismicity in the vicinity of the Mont Terri underground laboratory.

Exhumed fault scarps and drainage modification as proxies of neotectonics at the Abu Dabbab area, Eastern Desert, Egypt [PDF]

open access: yes, 2008
The basement rocks, Neogene sediments and Quaternary alluvial deposits in the Abu Dabbab area, Eastern Desert of Egypt, are deformed by N-S, NE-SW, NW-SE and E-W trending faults.
