Estimating Ice Cover on the Great Lakes Using Seismic Ambient Noise
Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.Abstract Lake ice impacts seismic noise on nearby seismometers, and therefore seismic observations can be used to monitor ice changes. However, the transfer function describing how lake‐microseism noise covaries with ice cover has not been quantified.

Automatic Classification of Microseismic Signals Based on MFCC and GMM-HMM in Underground Mines
Shock and Vibration, 2019 In order to mitigate economic and safety risks during mine life, a microseismic monitoring system is installed in a number of underground mines. The basic step for successfully analyzing those microseismic data is the correct detection of various event ...

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.Abstract We use recently compiled GNSS velocities across the Zemuhe‐Daliangshan fault zone, part of the central Xianshuihe‐Xiaojiang fault system, to reconcile a long‐standing mismatch between geodetic and geologic slip‐rate estimates. We show that conventional elastic dislocation models yield slip rates and locking depths that conflict with seismic ...

The von Neumann Stability Analysis of the Fixed‐Stress Schemes in Poroelastodynamics
International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 4, Page 1939-1951, March 2026.ABSTRACT We investigate splitting schemes based on the fixed‐stress sequential approach for poroelastodynamic problems. To assess numerical stability, we perform the von Neumann stability analysis on several fixed‐stress schemes for poroelastodynamics, including staggered, stabilized, and iterative methods. Our analysis reveals that while the staggered

Deglitching Martian Seismic Data: Application to Marsquake Detection
Earth and Space Science, Volume 13, Issue 3, March 2026.Abstract NASA's InSight mission investigates the interior structure of Mars. The data is characterized by multiple non‐seismic signals with varying attributes, including high‐energy instrumental noise, known as glitches, which frequently exhibit large linear polarization.

Four Phenomena Observed on Microseismic Data
, 2013 Passive seismic data recorded in observation wellbores for hydraulic fracture monitoring are usually used to detect P- and S-wave arrivals from induced microseismic events. The time arrivals for these events are used to compute source locations to build a fracture location map.
