Biodegradable, Biologically Safe Nanogenerators for Self‐Powered Bio‐Integrated Systems
Small Structures, Volume 7, Issue 8, August 2026.Biodegradable TENGs, PENGs, and hybrid systems convert biomechanical motions into electrical signals while safely degrading after use. This review highlights their working mechanisms, biodegradable material platforms, and wearable and implantable bio‐integrated applications, including motion and respiration monitoring, biosignal detection, electrical ...

Pressurization of Shallow Magma Reservoir Preceding Basaltic Eruptions at an Open‐Vent Volcano
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.Abstract Open‐vent volcanoes are characterized by the persistent activity of outgassing, lava effusion and mild explosions, which is, however, occasionally interrupted by more violent explosive activity (paroxysm), for example, Stromboli (Italy). In spite of the different (two orders of magnitude) explosive intensities and different petrological magma ...

3D elastic time-frequency full-waveform inversion
, 2015 In this work I present the theory and implementation of a 3D elastic full waveform inversion. The implementation is based on the adjoint-state method using a time-frequency approach. Synthetic applications in transmission acquisition geometry show the ability of the method to reconstruct elastic parameters of different 3D subsurface structures ...

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.Abstract Seismic attenuation provides sensitivity to fracture density, fluid saturation, and pore geometry that complements velocity, enabling quantitative imaging of fracture architecture and associated fluid‐pathways in near‐surface bedrock. Yet high‐resolution attenuation models remain rare in refraction studies due to amplitude‐fidelity and ...

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.Abstract Fault slip occurs in both seismic and aseismic styles with spatial variability across scales, yet non‐unique source inference limits our ability to resolve slip complexity and dynamics. Here we evaluate the effect of spatial smoothing regularization in Bayesian frameworks by comparing an unregularized (BUR) approach that samples distributed ...

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.Abstract We develop a sensitivity‐guided, surrogate‐assisted Bayesian framework to infer fracture network parameters from elastic waves. Synthetic fracture networks characterized by power‐law length exponent a $a$, fracture density d $d$, and percolation parameter p $p$ are constructed.

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.Abstract The diverse volcanic activity in the Alaska Peninsula section of the Alaska‐Aleutian subduction zone is presumably caused by substantial variations in mantle wedge melting or trans‐crustal processes beneath the arc. In this study, we investigate sub‐arc melting beneath the Alaska Peninsula by measuring P‐wave attenuation, as attenuation is ...

Sedimentology, Volume 73, Issue 5, Page 1378-1402, August 2026.ABSTRACT Tsunami deposits serve as geological records of past events and are essential for understanding the occurrence and dynamics of tsunamis. However, conventional research has largely focused on sandy and boulder deposits, leaving gravel‐dominated tsunami deposits comparatively underexplored; furthermore, their characteristics and formation ...

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.Abstract Long‐term SO2 emission rate time series are critical for deciphering the subsurface processes regulating open‐vent volcanoes, yet extracting cyclical drivers from continuous degassing records remains challenging. We analyze a 14‐year (2006–2020) SO2 emission rate data set from Whakaari/White Island, New Zealand, identifying five chronological ...

Linking Interseismic Locking to Coseismic Rupture: The 2025 Mw 8.8 Kamchatka Earthquake
Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.Abstract We investigate interseismic locking on the Kamchatka megathrust, source of the 2025 Mw 8.8 earthquake, using a data‐driven probabilistic framework. Horizontal GNSS velocities constrain a boundary element model on a triangulated megathrust geometry, while an algorithmic sampling strategy estimates the locking probability for fault elements ...
