Volcanic process in block’s crust

open access: yesЛитосфера, 2015
Within the author's rotational concept a brief review of geodynamic movements of the block rotating nonlinear geomedium is done. Such geodynamic movements appear to be consistent with the volcanic process. It is shown that the magma chambers that fed the

Rift Development, Tectonic Forcings, and Magmatic Feedbacks at Santorini and Kolumbo Volcanoes Constrained by Scientific Drilling and Core‐Seismic Integration

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract Volcanism in continental rifts, rifted volcanic arcs, and back‐arc basins is fundamentally coupled with crustal extension. However, the precise geometry and timing of the fault systems that facilitate magma transport and accommodate extension remain poorly constrained.

The Zitácuaro Volcanic Complex, Michoacán, Mexico: magmatic and eruptive history of a resurgent caldera

open access: yesGeofísica Internacional, 1997
The Zitácuaro Volcanic Complex (ZVC) rises on a basement of metamorphic rocks of Late Jurassic-Early Cretaceous age, and volcanic rocks, limestones, and red beds of Cretaceous age.

The Decline of a Caldera‐Filling Glacier at Volcán Sollipulli, Chile

open access: yesJournal of Geophysical Research: Earth Surface, Volume 131, Issue 6, June 2026.
Abstract Southern Andean glaciers have undergone fast retreat in recent decades. This results in reduced freshwater storage, contribution to sea‐level rise, and locally to the formation of glacial lakes, that may pose the risk of glacial lake outburst floods (GLOFs).

Terrestrial Analogs to Titan for Geophysical Research

open access: yesReviews 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 ...

Arc Heat Flow and Magmatic Heat Budgets

open access: yesReviews 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 ...

Risk Assessment of Introduced Fish Species as a Biodiversity Mitigation Effort in Lake Toba, North Sumatra, Indonesia

open access: yesZoodiversity
Lake Toba's environment and ichthyofauna are degrading due to human activities and the introduction of invasive fish species. Studies are needed to identify species, distribution patterns, densities and risks of introduced fish species, and these studies

Basement Geometry and Cover‐Basement Relationships in the Central‐Western Jaca‐Pamplona Basin (Southern Pyrenees): Along‐Strike Variations and Role of Structural Inheritance

open access: yesTectonics, Volume 45, Issue 6, June 2026.
Abstract This study presents a detailed, geometrical characterization of the central‐western domain of the Jaca‐Pamplona Basin based on a combined interpretation of seismic and surface data and the construction of four serial cross‐sections. For the studied portion of the basin, our results highlight that the basement is notably folded and faulted and ...

A Machine Learning Approach for Volcanic Eruption Mass Estimation

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.
Abstract Estimation of total volcanic erupted mass—the primary metric of eruption magnitude—is typically performed post‐eruption relying on dense monitoring of ground‐based seismology, gravity and deformation instrumentation, and therefore exists for only ∼100 of ∼1280 volcanoes worldwide.

A Spatially Explicit Distribution Model to Support Conservation Strategies for Isolated Small‐Ranged Species: A Case Study From Galápagos

open access: yesDiversity and Distributions, Volume 32, Issue 6, June 2026.
ABSTRACT Aim This study aimed to test the effectiveness of a hierarchical, spatially explicit, Bayesian modelling framework combining Integrated Nested Laplace Approximation (INLA) with Stochastic Partial Differential Equation (SPDE) as an alternative to traditional Species Distribution Models (SDMs), particularly in cases where standard assumptions ...
