The b $b$‐Value Tomography of the Calabrian Arc
Earth and Space ScienceAbstractIn the Calabrian Arc subduction zone, the notable lack of seismicity at depths near 100 km strongly suggests the presence of slab detachment. Contrary to typical patterns, where ‐values decrease with depth, our b‐value mapping reveals unexpectedly high ‐values at these depths.

The Mean Ratio Set for $ax + b$ Valued Cocycles
Publications of the Research Institute for Mathematical Sciences, 1996 Let X=\prod^∞_{\iota =1} Z_{l(\iota)} be acted upon by the group Γ=\bigoplus^∞_{\iota =1}Z_{l(\iota)} of changes in finitely many coordinates and

Optimum b value for resolving crossing fibers: a study with standard clinical b value using 1.5-T MR [PDF]
Neuroradiology, 2010 We sought to investigate the optimum b value for resolving crossing fiber using high-angular resolution diffusion imaging (HARDI)-based multi-tensor tractography. The study tested the standard b values that are commonly used in the routine clinical setting.Ten normal volunteers (five men and five women) with a mean age of 26.3 years (range, 22-32 years)

Earth, Planets and Space, 2022 We propose a statistical analysis method to identify common features of seismic activity that are indistinguishable from most other seismicity, and to find anomalous activity that differs from these common features.

Are volcanic seismic b -values high, and if so when? [PDF]
Journal of Volcanology and Geothermal Research, 2015 Abstract The Gutenberg–Richter exponent b is a measure of the relative proportion of large and small earthquakes. It is commonly used to infer material properties such as heterogeneity, or mechanical properties such as the state of stress from earthquake populations.

2021年江苏天宁MS4.2地震前后b值与视应力时空变化特征研究
Dizhen xuebao本文以 （29°N—37°N，117°E—124°E）为研究区，基于该区域 2014—2023 年的地震目录与波形数据，通过分析江苏天宁 MS4.2 地震前后的 b 值与差视应力变化，探究该地震前震源区是否存在应力累积过程。结果表明：2019 年4月至2020 年 2 月，天宁MS4.2地震周边区域b值呈上升趋势；2020 年 2 月后 b 值转为下降，且该趋势持续至地震发生；差视应力则呈现三阶段变化：2019 年12 月前呈下降趋势，2020 年1月至2021年7月转为上升后再次下降。天宁地震发生前 ...

b-Values Observations in Taiwan: A Review
Terrestrial, Atmospheric and Oceanic Sciences, 2015 High seismicity with spatial heterogeneity in Taiwan makes this region one of the best natural laboratories for seismological researches. Numerous seismicity studies, including the b-value, have been performed for more than one century. One of the possible ways to mitigate seismic risk is predicting an impending earthquake through various kinds of ...
