Making Mining Licit: Gold, Commodification, and the Everyday Performance of Law in Colombia

American Anthropologist, Volume 128, Issue 3, Page 480-493, September 2026.
ABSTRACT Ethnographies of resource‐making have shown that the extraction of resource value from objects is premised on obviating the emplaced lifeworlds that surrounded objects before they traveled to consumer markets. Much of this literature looks at such supply‐chain disentanglement from the viewpoint of corporate and formal regulatory practices ...

Small‐scale adaptation to geothermal soil heating in a perennial herb revealed by combining crosses and transplantations

New Phytologist, Volume 251, Issue 5, Page 3008-3020, September 2026.
Path diagrams showing the results of piecewise structural equation models examining how fitness (total number of seeds in flowering individuals) of Cerastium fontanum depended on temperature at planting site, temperature difference, mating type, and flowering time (FFD, first flowering date) in each of the two study years.

Mount St. Helens Retrospective: Lessons Learned Since 1980 and Remaining Challenges

Frontiers in Earth Science, 2018
Since awakening from a 123-year repose in 1980, Mount St. Helens has provided an opportunity to study changes in crustal magma storage at an active arc volcano—a process of fundamental importance to eruption forecasting and hazards mitigation.

Deep Seismic Tremors in the 2025 Santorini Seismo‐Volcanic Crisis Highlight Magmatic Feeding From a Mid‐Crustal Reservoir

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract An intense seismic swarm started on 27 January 2025 in the Santorini‐Amorgos region and lasted for approximately 45 days. A widely observed seismic tremor on 14 February 2025 suggested a volcanic origin for the 2025 Santorini crisis. Here we present an in‐depth combined seismological analysis of the earthquakes and tremors that occurred during

An Inflating Upper Mantle Magma Reservoir Beneath the Tip of the Condor Seamount, Azores Revealed by Rapid‐Response Ocean‐Bottom‐Seismometer Data

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Condor Seamount is among the most seismically active regions on the Azores Plateau. In December 2019, an earthquake crisis occurred at the tip of the seamount, which was strongly felt on nearby islands. Two months after the peak of the crisis, we deployed a local network of five ocean‐bottom seismometers around the seamount, recording ...

Lower crustal magmatic processes and andesite genesis at Shiveluch Volcano

Volcanica
The silicic melts that eventually erupt at arc volcanoes are produced in the lower crust, yet, the storage conditions of magma in the lower crust have not been the topic of extensive study.

High Melt Fraction Induced by the Dehydration Melting Near the 410‐km Discontinuity

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract The water‐rich mantle transition zone, coupled with the low water storage capacity of the upper mantle, suggests that dehydration melting occurs just above the mantle transition zone near the 410‐km discontinuity. However, the melt fraction produced by the dehydration melting process remains poorly constrained.

Global Evidence for Off‐Axis Flexural Modification of Abyssal Hill Faults at Mid‐Ocean Ridges

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Young oceanic lithosphere flexes as axial topography decays across mid‐ocean ridge shoulders, yet this deformation has been quantified at only a few segments, leaving its global expression poorly constrained. We analyzed 50 across‐axis bathymetric profiles from 21 regions spanning slow to fast spreading rates, identified 1,201 abyssal‐hill ...

Magmatic Storage and Volatile Fluxes of the 2021 La Palma Eruption

Geochemistry, Geophysics, Geosystems
The 2021 La Palma eruption (Tajogaite) was unprecedented in magnitude, duration, and degree of monitoring compared to historical volcanism on La Palma.

An interdisciplinary approach to the pre- and syn-eruptive magma dynamics during the Tajogaite monogenetic eruption (La Palma, 2021)

Frontiers in Earth Science
The 2021 Tajogaite eruption (La Palma, Canary Islands) provides a unique opportunity to investigate magma dynamics in magmatic systems where developed and monogenetic volcanoes coexist.
