Possible Problems of Evaluation of Spatial-Temporal Features of Earthquake Catalog Representativity: Case Study for the Kamchatka Catalog of Geophysical Survey of RAS

Вестник Камчатской региональной ассоциации "Учебно-научный центр". Серия: Науки о Земле, 2019
The completeness of the catalog, understood as the magnitude threshold from which earthquakes are recorded without gaps, is usually determined by the linear part of the magnitude-frequency relationship in accordance with the Gutenberg-Richter law.

Characteristics of foreshock activity inferred from the JMA earthquake catalog

Earth, Planets and Space, 2018
We investigated the foreshock activity characteristics using the Japan Meteorological Agency Unified Earthquake Catalog for the last 20 years. Using the nearest-neighbor distance approach, we systematically and objectively classified the earthquakes into

The earth's rotation-dominated seismicity preceding the 2023 MW7.8 Gaziantep, Türkiye, earthquake

Geodesy and Geodynamics
For earthquakes (M ≥ 4.0) occurring along and around the East Anatolian fault zone and the Dead Sea fault zone within ten years immediately before the MW7.8 Gaziantep earthquake, Türkiye, of February 6, 2023, we explored the correlation between ...

A test on methods for Mc estimation and spatial-temporal distribution of b-value in the eastern Tibetan Plateau

Frontiers in Earth Science
Seismic b-value is one of the most important parameters for seismological research and seismic hazards assessment, while the accuracy of the b-value largely depended on the completeness of seismic catalog.

Spatial–temporal variations of b-values prior to medium-to-large earthquakes in Taiwan and the feasibility of real-time precursor monitoring

Earth, Planets and Space
This study explores the b-value variations prior to M ≥ 6.0 earthquakes in Taiwan, examining their potential as earthquake precursors. Focusing on the 2018 Hualien earthquake and others between 1999 and 2021, we found that many large earthquakes occurred

Study on damage and fracture characteristics of wood based on acoustic emission b-value and seismic magnitude difference entropy

Journal of Wood Science
To assess the damage and fracture behavior of wood under load, a wood damage assessment method was proposed based on acoustic emission (AE) b-values and seismic magnitude difference entropy. First, AE signals from Pinus sylvestris var.

2024年云南永胜ML5.1震群发震断层和成因探讨

Dizhen xuebao
基于云南省区域数字化地震监测台网宽频带地震波形与区域速度模型，综合运用双差重定位方法和 CAP 方法对2024年云南省丽江市永胜县ML5.1震群进行重定位及震源机制解反演，并结合流体扩散模型、衰减参数p值、b 值及区域构造背景对震群的特征及成因进行综合分析。结果显示：该震群在空间上沿 NW 和 NE 走向形成了长约 27 km、宽约 10 km 的长方形条带，震源深度主要集中于8—14 km；受区域 NNW 向主压应力的作用，震源机制以左旋走滑为主（节面Ⅱ的走向为28°±2°，滑动角为−13°±5 ...
