Restoration Ecology, EarlyView.Abstract Introduction Seismic lines represent one of the most extensive and persistent anthropogenic disturbances in boreal peatlands, limiting forest regeneration and altering key ecosystem functions. Inverted mounding is increasingly applied to elevate planting microsites above shallow water tables, yet evidence on short‐ to medium‐term biophysical ...

Building a Continental‐Scale Geodetic Network: The Plate Boundary Observatory (PBO)
Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.Abstract The Plate Boundary Observatory (PBO) transformed the use of geodesy in North America to study crustal deformation and plate boundary processes by establishing a continental‐scale, standardized, open‐access geodetic network. Built and operated by UNAVCO between 2003 and 2018 as part of the National Science Foundation (NSF)‐funded EarthScope ...

Wavelet‐Based Hurst Exponent Estimation
WIREs Computational Statistics, Volume 18, Issue 3, September 2026.The review explores how wavelet‐based methods for estimating the Hurst parameters have developed from their theoretical roots to real‐world applications in fields like biology, engineering, and telecommunications. The review aims to highlight key techniques, compare their strengths and limitations, and point out challenges that still need to be ...

Earthquake Spectra, Volume 42, Issue 3, August 2026.Fire sprinkler systems are critical for fire safety, but their functionality can be impaired by seismic damage. This study develops new seismic fragility functions for acceleration‐sensitive damage requiring monitoring, maintenance, and repair in code‐compliant fire sprinkler piping systems, using experimental data from full‐scale experimental tests ...

Earthquake Spectra, Volume 42, Issue 3, August 2026.The 1931 Hawke's Bay earthquake (∼MS 7.8) stands as one of New Zealand's most devastating, causing widespread liquefaction and damage across the city of Napier. However, Napier remains underrepresented in liquefaction hazard studies as compared to other regions in the country.

Validation of ShakeMaps Created From Global Navigation Satellite System (GNSS) Velocities
Earthquake Spectra, Volume 42, Issue 3, August 2026.Ground velocity observations generated through a time difference of Global Navigation Satellite Systems (GNSS) phase observables and orbits have been shown to be comparable to seismic recordings without clipping during intense ground motions. Computing GNSS velocities is also computationally scalable and increases the density of ground motion ...

Coarse Sediment Transport in a Near‐Terminus Subglacial Channel
Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.Abstract We present the first large‐sample, spatially resolved measurements of coarse sediment transport within a subglacial meltwater channel. We released 324 radio‐tagged pebbles into a near‐terminus channel of Glacier d’Otemma, Switzerland, and monitored their positions through 10–50 m of ice during the mid to late melt season.

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.Abstract The dynamic slip behavior of faults is strongly influenced by the thermal and hydraulic properties of pore fluids, which control thermal pressurization (TP) during seismic slip. While previous experiments showed significant TP‐induced weakening in DI‐water‐saturated Groningen sandstone gouges, in situ fluids are brine or brine–gas mixtures ...

Nonlinear Response‐History Analyses of Masonry and Mixed Structures With HybriDFEM
Earthquake Engineering &Structural Dynamics, Volume 55, Issue 8, Page 1694-1709, 10 July 2026.ABSTRACT The hybrid discrete‐finite element (HybriDFEM) method, previously developed to perform static and modal analysis in discrete and coupled discrete‐finite element models, is extended to nonlinear response‐history analyses. The equations of motion for the HybriDFEM model are solved through various numerical time‐integration schemes, both explicit
