OBS Data Mining Reveals Seismic Structure and Dynamics of the Oceanic Blanco Transform Fault, Northeast Pacific

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract Deformation along oceanic transform faults is partitioned between seismic and aseismic slip, controlled by lithology, thermal structure, and fluid circulation. We analyze one year of data from a 54‐station ocean bottom seismometer network deployed across the Blanco Transform Fault (BTF), Northeast Pacific.

Hydrological Impact of Earthquakes on Reverse and Normal Faults: Results From Numerical Models

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract I investigate earthquake‐induced hydrological signals related to poroelastic deformation, thermal pressurization, fault‐zone dilatancy and rupture of a pressurized reservoir at depth. This is performed using a two dimensional plane strain model that simulates ruptures on reverse and normal faults governed by rate‐and‐state friction coupled to ...

Multi‐Scale Rate‐ and Roughness‐Dependent Frictional Constitutive Law and Dynamic Earthquake Sequence Simulation

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract The physical mechanisms that govern the multi‐scale source properties of earthquakes, such as fracture energy scaling, where the dynamic energy dissipation of earthquakes scales with fault slip, remain debatable. We introduced the rate‐ and roughness‐dependent friction (RRF) law which accounts for the multi‐scale roughness evolution of the ...

Sensitivity of Soil Chemical Erosion Rate to Climate and Dust Along a 2.8‐km Elevation Transect at San Jacinto Mountain, California

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 6, June 2026.
Abstract Chemical weathering is of wide interest because it breaks down minerals, releases nutrients, weakens rock, and draws down atmospheric CO2. To quantify the sensitivity of soil chemical erosion rate to climate and dust, we measured soil chemical erosion rate, dust deposition rate, and soil climate at 18 ridgetop sites along a ∼2.8‐km elevation ...

Terrestrial Analogs to Titan for Geophysical Research

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas—methane—replacing the Earth's water, leading to an active meteorology with rainfall and surface manifestations ...

Backprojection of the high-frequency radiation released during the Pisagua (Chile) earthquake (01/04/2014, Mw 8.1) and the Iquique aftershock (03/04/2014, Mw 7.6)

, 2014
Northern Chile has recently been struck by the Mw 8.1 Pisagua earthquake, which occurred on 01/04/2014 and partially filled the Iquique seismic gap. The Pisagua earthquake has been preceded by intense foreshock activity which started in July 2013 and ...

Rock Physics of the Critical Zone: Models, Inversion, and Interpretation

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Rock physics models link geophysical measurements with subsurface petrophysical properties, such as porosity, mineral composition, and fluid saturation. While originally developed for hydrocarbon exploration, these models are increasingly applied in the near surface for quantitative interpretation of geophysical data.

Estimation high-frequency energy radiation of the 2013 Lushan Mw6.6 earthquake by envelope inversion

Abstract This study uses the envelope inversion method to investigate the characteristics of high-frequency energy radiation of the 2013 M w 6.6 Lushan earthquake. We selected near field acceleration records from two small earthquakes as empirical Green’s functions and applied the ...

Arc Heat Flow and Magmatic Heat Budgets

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract We evaluate hydrothermal heat loss from 11 volcanic‐arc segments (∼6,000 km of arc length, ∼10% of the global total), motivated by the observation that much magmatic heat ultimately crosses the land surface as heated aqueous fluid. Heat loss takes place by volcanic eruption, geothermal heat conduction to the surface, fumarolic (vapor ...
