Stress Model of California: Fault‐Stress Interactions Across a Complex Plate Boundary System From Focal Mechanisms of Small Earthquakes

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract California, located along the transform boundary between the Pacific and North American plates, hosts a complex fault system, a long history of damaging earthquakes, and frequent small earthquakes. While earthquakes arise from the buildup and release of elastic stress, detailed knowledge of principal stress orientations, absolute stress ...

An adaptive multiscale algorithm for efficient extended waveform inversion

, 2017
Subsurface-offset extended full-waveform inversion (FWI) may converge to kinematically accurate velocity models without the low-frequency data accuracy required for standard data-domain FWI.

From Extension to Strike‐Slip Faulting Along the Western Continuation of the North Anatolian Fault in the Northern Aegean Sea: Structural, Geochronological and Geochemical Constraints

Tectonics, Volume 45, Issue 4, April 2026.
Abstract The Northern Aegean region preserves a complex deformation pattern shaped by Miocene extension driven by retreat of the Hellenic subduction system, later overprinted by Plio–Pleistocene transtension linked to the westward propagation of the North Anatolian Fault (NAF). Although numerous structural, geophysical and geochronological studies have

Paleostress analysis on Paleozoic syn-depositional faults in the eastern Alborz, northern Iran

Journal of Asian Earth Sciences: X
The Alborz Mountains of northern Iran stand out as an exceptional site for studying the Ediacaran-Paleozoic evolution of the northern Gondwana margin. The Alborz forms the inverted continental shelf of the Central Iranian microcontinent that was part of ...

The Magnetic Signature of Stress in Rocks

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Magnetic signatures preserved in rocks have long provided insight into Earth's evolution, revealing processes from plate tectonics to the habitability of Earth. While large impacts are known to impose extreme stresses (>1 GPa) and heat that fundamentally alters magnetic records, lower stresses typical of earthquakes have been considered ...

Stress and Rock Failure Near Salt Bodies: Insights From Field Observations, Kinematic Modeling, and Mechanical Analysis Near Arches National Park, Paradox Basin, Utah

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract Salt's inherent weakness and capacity for ductile deformation create significant mechanical contrasts that locally perturb the stress field in surrounding rocks, often leading to deviations from regional tectonic stresses. Variations in local stress are a critical factor for wellbore stability, seal integrity, and fluid flow in subsurface ...

Tectonic inversion of compressional structures in the Southern portion of the Paramirim Corridor, Bahia, Brazil

Brazilian Journal of Geology
The Paramirim Corridor represents the maximum inversion zone of the Paramirim Aulacogen. Reverse-to-reverse dextral shear zones and various types of folds dominate such corridor. These structures reflect a stress field that is WSW-ENE oriented, developed

Negative inversion, negative concord and sentential negation in the history of English [PDF]

, 2012
It is claimed in van Kemenade (2000: 62) that clauses with initial negative constituents are a context in which subject–verb inversion occurs throughout the history of English.

Evaluating Regional Stress Versus Structural Controls on a Middle Miocene Dike Swarm in the Sanbagawa Metamorphic Complex, Southwest Japan

Island Arc, Volume 35, Issue 1, January/December 2026.
ABSTRACT The Middle Miocene Takaiwa Rhyolite dike swarm in central Shikoku, southwest Japan, provides a key opportunity to evaluate whether arc‐parallel dikes record the regional stress field in a crustal domain with a pervasive ENE–WSW structural grain.
