Model‐Predicted Shear‐Wave‐Splitting Parameters in NE Japan: Comparison With Observations

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract We model olivine crystal preferred orientation (CPO) and shear wave splitting (SWS) in the mantle wedge, using the results of a 3‐D numerical thermomechanical model for the NE Japan subduction zone. The model predicts a quasi‐2‐D trench‐normal (E‐W) mantle wedge flow pattern beneath Tohoku, given the trench‐normal subduction, but a more ...

Citizen Seismology Without Seismologists? Lessons Learned From Mayotte Leading to Improved Collaboration

Frontiers in Communication, 2020
Starting the 10th May 2018, a series of earthquakes has hit Mayotte, a French island in the Indian Ocean. Facing a lack of seismic data, scientific information and communication from the authorities, the inhabitants took advantage of social media to ...

Fifty Years Later: Revisiting Viking 2 Seismic Signals Through InSight

AGU Advances, Volume 7, Issue 7, October 2026.
Abstract For nearly 50 years, the origin of the candidate seismic signals recorded by Viking 2 remained unresolved because of limited instrumental sensitivity, onboard observation, data compression, and the absence of Martian seismic context. Here we reconstruct the Viking seismic workflow and reinterpret the two Viking candidate events, recorded on ...

Full‐Waveform Seismic Tomography of the Upper Mantle Beneath the Arabia‐Eurasia Collision Zone

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Despite being one of the most recent major orogenic events, the timing of the Arabia‐Eurasia collision is still debated. Much of the discrepancy arises due to uncertainties over the amount of continental subduction of the Arabian passive margin and the timing of a hard collision of cratonic Arabian lithosphere with Eurasia.

Mantle Transition Zone Constraints on Slab Penetration and Slab‐Edge Mantle Flow Beneath the Kamchatka Peninsula

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Numerous seismic studies have reported the absence of a resolvable subducted slab beneath parts of northern Kamchatka, though the mechanism for this anomaly remains debated. We utilize 1,696 P‐to‐S receiver functions to image the mantle transition zone (MTZ) beneath the Kamchatka Peninsula and surrounding areas. Beneath southwestern Kamchatka,

Analytical models of volcanic ellipsoidal expansion sources

Annals of Geophysics, 2013
Modeling non-double-couple earthquakes and surficial deformation in volcanic and geothermal areas usually involves expansion sources. Given an ensemble of ellipsoidal or tensile expansion sources and double-couple ones, it is straightforward to obtain ...

Seismic characterization of pyroclastic flow activity at Soufrier Hills Volcano, Montserrat, 8 January 2007 [PDF]

, 2007
A partial dome collapse with concurrent pyroclastic flow (PF) activity occurred at Soufrière Hills Volcano (SHV), Montserrat on 8 January 2007. Pyroclastic density currents were observed to propagate from the Northwest and West sectors of the summit dome

Key Parameters for the Ionospheric Detection of Tsunamis From the 29 July 2025 Kamchatka Event

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract It has been demonstrated that tsunamis generate internal gravity waves (GWs) detectable in the ionosphere within 20–60 min after their generation at the ocean surface. Despite numerous simulation and observation studies on ionospheric signatures of tsunamis, the detection of Co‐tsunamic Ionospheric Disturbances (CTIDs) and distinguishing them ...
