Depositional and stratigraphic evolution of a Permian megalake system: Implications for seiche‐influenced models

open access: yesThe Depositional Record, Volume 12, Issue 2, April 2026.
During the Late Permian, the rise of the Gondwanides Belt trapped marine waters, giving birth to a vast megalake. This lake shifted between overfilled, balanced‐fill and underfilled stages that are recorded by high‐frequency accommodation changes, while meteorological seiches shaped the sedimentary dynamic and produced heterolithic beds.

Art Adds Value to Ecological Field Courses: A Multi‐Year Case Study in Higher Education

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
This study presents Earth Projects, an interdisciplinary, place‐based field course that merges ecology and ecological art (eco‐art) to foster deeper engagement with environmental learning. Pre‐ and post‐survey comparisons show that incorporating eco‐art can strengthen students' emotional connections to their identities, disciplines, and place.

Seismic Design of Concrete Dams: An Integrated Risk‐Informed Performance‐Based (RIPB) Framework

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 5, Page 1019-1049, 25 April 2026.
ABSTRACT This paper advances the integration of risk‐informed principles into the seismic design of dams—a domain long guided by standards‐based, largely deterministic approaches. While performance‐based earthquake engineering is well established for buildings and bridges, its systematic adoption in dam engineering remains limited. We first address two

Fighting Through Community Participation Based on Vegetative Conservation Approach of Wonogiri Reservoir Sedimentation in Sub - Watershed of Keduang [PDF]

open access: yes, 2012
Humans are the main trigger factors causes of sedimentation. It’s happened because of the farming and cultivation system that is not based on the principles of sustainable development. These human activities causes in damage to the environment in the

A Parallelized 3D Geomechanical Solver for Fluid‐Induced Fault Slip in Poroelastic Media

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 5, Page 2570-2586, 10 April 2026.
ABSTRACT We present a fully implicit formulation of coupled fluid flow and geomechanics for fluid injection/withdrawal in fractured reservoirs in the context of CO2$\textrm {CO}_2$ storage. Utilizing a Galerkin finite‐element approach, both flow and poroelasticity equations are discretized on a shared three‐dimensional mesh.

Monitoring of water volume in a porous reservoir using seismic data: Validation of a numerical model with a field experiment

open access: yesNear Surface Geophysics, Volume 24, Issue 2, Page 110-127, April 2026.
Abstract As global groundwater levels continue to decline rapidly, there is a growing need for advanced techniques to monitor and manage aquifers effectively. This study focuses on validating a numerical model using seismic data from a small‐scale experimental setup designed to estimate water volume in a porous reservoir.

Global Primary and Secondary Microseism Multi‐Decade Geographic Variation, Secular Intensification, and Period Lengthening

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Earth's long period background seismic wavefield is dominated by two distinct processes that couple ocean wave energy to a global microseism wavefield. We assess global microseism intensity in the secondary (4–10 s) and primary (14–20 s) bands, and across eight 2 s‐wide period bands between 4 and 20 s.

Fault Friction, Plate Rheology, and Mantle Torques From a Global Dynamic Model of Neotectonics

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Improvements in software, parallel computing, global data sets, and laboratory flow‐laws help to develop the global Earth5 thin‐shell finite‐element model of Bird et al. (2008, https://doi.org/10.1029/2007jb005460) into a benchmark study. All experiments confirm that modeled faults (other than megathrusts) have low effective friction of 0.085 ±

From Hurricane Irma to the Grindavík eruptions: volatility premiums in disaster governance

open access: yesDisasters, Volume 50, Issue 2, April 2026.
Abstract Environmental volatility can inflate property values even as it destroys them. To show how, this article pairs a postcolonial micro‐state in the Caribbean (Sint Maarten after Hurricane Irma) with a Nordic welfare town (Grindavík in Iceland following volcanic eruptions) because they occupy the opposite ends of the governance capacity spectrum ...

Recent Observations of Thwaites Glacier, West Antarctica Are Consistent With High Rates of Loss in Next 50 Years

open access: yesGeophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Thwaites Glacier has experienced accelerating mass loss, with rates increasing over fivefold since the 1990s. We apply transient calibration to two independent ice‐sheet models (STREAMICE and ISSM) using time‐varying velocity and surface elevation data from 2004 to 2017 to project future mass loss through 2067.
