Analysis of natural neutron flux in a seismically active zone [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2003
In a seismically active zone in the near Almaty area (Kazakhstan) since 1996 observations of variations of a natural neutron flux have been conducted.

Seismic Analysis of Soil-Concrete Structure System in Time Domain by Numerical Modeling of Earthquake Wave Propagation [PDF]

open access: yesپژوهش‌های زیرساخت‌های عمرانی
The behavior of a structure changes when it interacts with underlying soil, which acts as a flexible base, as compared to a rigid base condition. Given the importance of performance-based design, the direct method for soil-structure interaction (SSI ...

Tree growth response and adaptation to climate change and climate extremes: From canopy to stem

open access: yesJournal of Integrative Plant Biology, EarlyView.
This review synthesizes the responses and adaptations of tree growth, including canopy phenology, intra‐annual wood formation dynamics, and annual stem growth, to climate change and climate extremes. It highlights key knowledge gaps for future research to support sustainable forest management and enhance forest carbon storage under ongoing climate ...

New knowledge about shock events that affected the L‐chondrite parent body from two heavily shocked L6 meteorite finds

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract We report new results from a study of shock‐related features in the L6 ordinary chondrites Northwest Africa (NWA) 4672 and NWA 12841. Our observations confirm the occurrence of eight high‐pressure (HP) minerals in each meteorite, namely, ringwoodite, majorite, akimotoite, wadsleyite, albitic jadeite, lingunite, tuite, and xieite.

The Role of Political Actors in Realizing Sustainable European Energy Markets: Insights From the Trinational Upper Rhine Region

open access: yesRegulation &Governance, EarlyView.
ABSTRACT Against the background of the European decarbonization strategy, this study examines the extent to which the expansion of renewable energies can lead to tensions with the social and ecological dimensions of the sustainability concept. The study is based on qualitative interviews with 66 experts conducted in the trinational metropolitan region ...

Variations in precursory slip behavior resulting from frictional heterogeneity

open access: yesProgress in Earth and Planetary Science, 2018
Precursory seismicity is often observed before a large earthquake. Small foreshocks occur within the mainshock rupture area, which cannot be explained by simple models that assume homogeneous friction on the entire fault.

Longwave radiation anomalies associated with seismic activity in the northern Tibetan Plateau

open access: yesFrontiers in Earth Science
Seismically active northern Tibetan Plateau necessitates the application of remote sensing-driven earthquake precursor detection. We applied wavelet transform and power spectrum analysis to outgoing longwave radiation (OLR) from 37 M ≥ 5.0 earthquakes ...

Shear-Wave Radiation Patterns from Explosive and Earthquake Sources in Scattering, Heterogeneous Media

open access: yesSeismica
Distinguishing whether a seismic event is an earthquake or an explosion is a core problem in explosion monitoring. For simplistic models, earthquakes produce a predictable S-wavefield based on their radiation pattern, while an explosion produces no S ...
