A Numerical Study of the Effects of Density Contrast on Flow, Turbulence, and Mixing at the Negro/Solimoes Confluence, Brazil

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract Eddy‐resolving numerical simulations are conducted to investigate the effects of density contrast between the confluent flows on hydrodynamics, coherent structures and mixing downstream of the confluence between the Negro and Solimões Rivers, Brazil, which is characterized by both a large discharge (>100,000 m3/s) and a large aspect‐ratio (W/D

High Temperature Friction and Strength of Felsite and Basalt: Implications for Supercritical EGS at Krafla, Iceland

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract One promising potential site for extracting supercritical geothermal fluids is the Krafla volcano, Iceland, into which a borehole was drilled very close to a shallow rhyolite magma chamber at about 2 km depth. Besides the technical challenge to drill in this setting, the extreme temperature conditions of T > 900°C close to the magma body may ...

Automated Three‐Dimensional Reflection Traveltime Modelling to Extract 3D Dipping Layer Geometries

Geophysical Prospecting, Volume 74, Issue 4, May 2026.
ABSTRACT Steep geological structures are critical for improved understanding of tectonic processes and fluid circulation, particularly in crystalline settings. However, accurately determining their geometry at depth remains a challenge for conventional 2D surveys.

Online Jump and Kink Detection in Segmented Linear Regression: Statistical Optimality Meets Computational Efficiency

Journal of Time Series Analysis, Volume 47, Issue 3, Page 727-748, May 2026.
ABSTRACT We consider the problem of sequential (online) estimation of a single change point in a piecewise linear regression model under a Gaussian setup. We demonstrate that certain CUSUM‐type statistics attain the minimax optimal rates for localizing the change point.

Asperity‐Driven Cascading Rupture of a Mw 1.6 Induced Microearthquake

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Studies of small earthquake (M < 2) rupture processes traditionally rely on simplified models that assume symmetric slip or point sources. Using an exceptionally dense seismic network and empirical Green's function (EGF) analysis, we investigate the complex rupture of a Mw 1.6 microearthquake induced by hydraulic fracturing.
