An Application of the Theory of Fluctuation to Problems in Statistical Seismology

, 1928
The object of this investigation is to introduce the application of the theory of fluctuation to some problems of statistical seismology. We have investigated the fluctuation of the number of earthquakes instrumentally registered in some units of time ...

Common dependence on stress for the two fundamental laws of statistical seismology

, 2009
International audienceTwo of the long-standing relationships of statistical seismology are power laws: the Gutenberg-Richter relation describing the earthquake frequency-magnitude distribution, and the Omori-Utsu law characterizing the temporal decay of ...

The United States Magnetotelluric Array and the National Impedance Map

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract The United States Magnetotelluric Array (USMTArray) data set, collected in the years 2006–2024, consists of more than 1,700 long‐period magnetotelluric stations covering the entirety of the contiguous United States on a quasi‐regular 70 km grid.

Nuevas técnicas de deconvolución dispersa robusta [PDF]

, 2007
La deconvolución dispersa consiste en estimar una señal de reducido número de muestras no nulas a partir de un conjunto de observaciones ruidosas, que se suponen originadas por la convolución entre una señal de aspecto impulsivo y la respuesta al ...

Probabilistic estimation of the source component of seismic hazard in North-Eastern Brazil

Heliyon
Stable continental regions pose unique challenges for conducting Probabilistic Seismic Hazard Analysis because the earthquake activity driving mechanisms are poorly understood.

Aerial and Space‐Borne Seismology on Venus: Viability and Design Implications for Future Missions

Earth and Space Science, Volume 13, Issue 6, June 2026.
Abstract Venus' evolution remains a mystery because of the lack of in situ geophysical data to constrain its interior structure. Recently‐selected planetary missions VERITAS (NASA), DAVINCI+ (NASA), and EnVision (ESA) will investigate the planet's interior, surface, and atmospheric chemistry.

Integrating Olivine Diffusion Chronometry With Monitoring Data to Decipher the Magma Dynamics at the Submarine Fani Maoré Volcano

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract Monitoring data are critical for understanding volcanic unrest and eruption, but they often lack the ability to constrain the pre‐eruptive magma processes. As such, an increasing number of studies couple monitoring data with petrological tools to obtain insights into the causes and durations of magmatic processes. The 2018–2020 eruption of the

Fracture mechanics of volcanic eruptions [PDF]

, 2009
Seismology is a key tool in the forecasting of volcanic eruptions. The onset of an eruption is often preceded and accompanied by an increase in local seismic activity, driven by fracturing within the edifice.

Transient Porosity During Fluid‐Mineral Interaction. Part 1: In Situ 4D Tomography

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract Fluid‐induced mineral replacement reactions play a key role in controlling porosity generation and permeability evolution in geologic systems. However, the dynamic feedback between pore structure development and fluid transport remains poorly quantified. This study investigates the spatiotemporal evolution of reaction‐induced pore space in the

Transient Porosity During Fluid‐Mineral Interaction, Part 2: Reconstruction Using Generative AI

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract Quantifying fluid–rock interactions within the lithosphere is vital for both geological processes and applications such as CO2 ${\text{CO}}_{2}$ storage and geothermal energy development. Mineral replacement reactions generate transient pore networks that enhance fluid flow, yet many pores become isolated once reactions are completed, reducing
