A prototype-based rockburst types and risk prediction algorithm considering intra-class variance and inter-class distance of microseismic data

Frontiers in Earth Science
The prediction and classification of rockburst risk based on microseismic data is the premise of preventing rockbursts during deep mine excavation. By reviewing previous studies, this paper finds two problems that hinder the rockburst prediction: 1 ...

Space Correlation Constrained Physics Informed Neural Network for Seismic Tomography

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 2, April 2026.
Abstract Physics‐informed neural networks (PINNs) integrate physical constraints with neural architectures and leverage their nonlinear fitting capabilities to solve complex inverse problems. Tomography serves as a classic example, aiming to reconstruct subsurface velocity models to improve seismic exploration.

Oblique Convergence in the Himalayas of Western Nepal Deduced from Preliminary Results of GPS Measurements [PDF]

, 1999
A GPS network consisting of 29 sites was installed in central and western Nepal, with measurements taken in 1995 and partial remeasurements in 1997. Data suggest 15 +/−5 mm/yr of N180° convergence between the Higher Himalayas and India, a result that is ...

An Effective Physics‐Informed Neural Operator Framework for Predicting Wavefields

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 2, April 2026.
Abstract Solving the wave equation is fundamental for many geophysical applications. However, numerical solutions of the Helmholtz equation face significant computational and memory challenges. Therefore, we introduce a physics‐informed convolutional neural operator (CNO) (PICNO) to solve the Helmholtz equation efficiently.

Injection Induced Seismicity in Complex Fault Zone Architecture

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Modeling of injection‐induced seismicity plays a significant role in understanding the seismic risks associated with different anthropogenic activities including sub‐surface energy harvesting and CO2 ${\text{CO}}_{2}$ sequestration. Here we investigate multi‐cycle modeling of induced seismicity in a complex fault zone hosting a primary fault ...

Observations of the seasonality of the Antarctic microseismic signal, and its association to sea ice variability [PDF]

, 2011
International audienceSeismic noise spectra at all seismic stations display two peaks in the 1-20 s period band, called primary and secondary microseisms. They are caused by the coupling of ocean waves into Rayleigh waves. At most locations, microseismic

Distinct Crustal Structure Across the Alpine Fault, New Zealand: Seismic Imaging of a Through‐Going Vertical Fault Beneath Its Central Section

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract The Alpine Fault (Aotearoa New Zealand) is a major plate boundary transform fault, that quasi‐periodically hosts large (M7‐8) to great (M8+) earthquakes. The fault is thought to be segmented with sections rupturing both individually and in combination.
