A theoretical basis of the moment magnitude scale

open access: yesEarth, Planets and Space
To measure the size of an earthquake, we can use two physically different quantities: the radiated seismic energy $$E_{{\text{R}}}$$ E R , from which seismic magnitude scales are defined, and the seismic moment $$M_{0}$$ M 0 .

A review on rockburst prediction and prevention to shape an ontology‐based framework for better decision‐making for underground excavations

open access: yesDeep Underground Science and Engineering, Volume 5, Issue 2, Page 331-349, June 2026.
A scientometric analysis of 2449 journal articles and a comprehensive review of 336 papers were conducted, discussing and identifying challenges and research gaps in rockburst prediction and prevention and proposing an ontology‐based framework for better decision‐making in underground excavations. Abstract With underground engineering projects becoming

Seismic Data, Photographic Images and Physical Modeling of Volcanic Plumes as a Tool for Monitoring the Activity of Nevado del Ruiz Volcano, Colombia

open access: yesFrontiers in Earth Science, 2018
Quantification of volcanic plume parameters is a fundamental task to characterize the behavior of an active volcano. The volcanic plume mass, flow rate and ash injection were determined from seismic data, in addition to photographic images and ...

Interpretable Tree‐Based Models for Predicting Short‐Term Rockburst Risk Considering Multiple Factors

open access: yesEnergy Science &Engineering, Volume 14, Issue 6, Page 2941-2960, June 2026.
Interpretable tree‐based models integrate microseismic, geological, and mining indicators to predict short‐term rockburst risk. SHAP analysis reveals the dominant role of energy‐related features and clarifies nonlinear factor interactions, enabling transparent and reliable early‐warning in deep coal mines.

Laboratory Hydrofractures as Analogs to Tectonic Tremors

open access: yesAGU Advances
The fracture of Earth materials occurs over a wide range of time and length scales. Physical conditions, particularly the stress field and Earth material properties, may condition rupture in a specific fracture regime.

On the modeling of strong motion parameters and correlation with historical macroseismic data: an application to the 1915 Avezzano earthquake

open access: yesAnnals of Geophysics, 1995
This article describes the results of a ground motion modeling study of the 1915 Avezzano earthquake. The goal was to test assuinptions regarding the rupture process of this earthquake by attempting to model the damage to historical monuments and ...

Climatic, lithologic and topographic control on alpine rock fracturing and talus evolution

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 6, June 2026.
Investigating Holocene rockwall–talus systems in an Alpine valley revealed that lithologic and topographic conditions in concert with climatic‐driven stresses and time since deglaciation result in rockwall fracture patterns that control rockfall size, erosion rates and the characteristics and evolution of talus.

The 2021 Mw8.1 Kermadec Megathrust Earthquake: An Event Rupturing the Slab‐Mantle Interface With Up‐Dip High‐Frequency Seismic Energy Radiation

open access: yesGeophysical Research Letters
Megathrust earthquakes often break the slab‐crust interface and radiate high‐frequency seismic waves from the down dip of their coseismic slip. In contrast, we show that the 2021 Mw8.1 Kermadec earthquake deviates from this mode. We resolve the kinematic

Multiple-event analysis of the 2018 ML 6.2 Hualien earthquake using source time functions

open access: yesTerrestrial, Atmospheric and Oceanic Sciences, 2019
Through forward multiple-event analysis of teleseismic P-waves using source time functions (STFs), derived by non-negative time-domain deconvolution, we inferred the rupture features of the 2018 Hualien earthquake.
