An electrochemical hypothesis of earthquakes exploring a theoretical link between radiated seismic energy and Pourbaix potential [PDF]
Scientific ReportsEarthquakes are measured using well-defined seismic parameters such as seismic moment ( $$M_o$$ ), moment magnitude ( $$M_w$$ ), and released elastic energy (E).

Terrestrial, Atmospheric and Oceanic Sciences, 2022 Key points logEs is proportional to 2.0ML for the Shoufeng earthquake sequence in Taiwan. A crossover magnitude detected at ML = 4.0 divides the MW–ML relation into two parts. For ML > 4.0, logM0 ∝ 0.67ML and MW ∝ ML; for ML

Seismo-acoustic energy partitioning of a powder snow avalanche [PDF]
Earth Surface Dynamics, 2020 While flowing downhill, a snow avalanche radiates seismic waves in the ground and infrasonic waves in the atmosphere. Seismic energy is radiated by the dense basal layer flowing above the ground, while infrasound energy is likely radiated by the powder ...

Quantitative assessment of energy changes in underground coal excavations using numerical approach
Geohazard Mechanics, 2023 Coal burst is caused by a dynamic and unstable release of energy within the overstressed rock mass/coal during the mining process. Although the occurrence of coal burst is a result of the complex impacts of many factors, a major component of coal burst ...

Single-block rockfall dynamics inferred from seismic signal analysis [PDF]
Earth Surface Dynamics, 2017 Seismic monitoring of mass movements can significantly help to mitigate the associated hazards; however, the link between event dynamics and the seismic signals generated is not completely understood.

Dizhen xuebao, 2021 根据地震波衰减特性，采用一维速度模型开展了快速测定辐射能量ES和能量震级Me的方法研究。利用全球地震台网和国家数字测震台网提供的宽频带资料，测定了2014—2019年间MW≥6.0的115次浅源地震的辐射能量和能量震级，将计算结果与其它机构的结果进行对比。结果表明：利用本文方法可在得到地震数据半小时内计算出稳定的Me，且本文的测定结果与美国地震学研究联合会的结果基本一致。地震造成的灾害与能量震级的大小密切相关，当Me＞MW时，地震灾害较为严重；在所有的地震类型中，发震断层类型为走滑型时 ...
