Hydrothermal Sealing at Turrialba, Poás, and Rincón de la Vieja Volcanoes (Costa Rica) Promotes Phreatic and Phreatomagmatic Eruptions

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 11, November 2026.
Abstract Hydrothermal sealing is a mechanism thought to be responsible for challenging‐to‐forecast phreatic and phreatomagmatic eruptions. To better understand this process, we present a study in which we assessed the textural, mineralogical, and physical properties (porosity, permeability, and tensile strength) of blocks of hydrothermal seal that were

Microeukaryotic Diversity and Habitat Structuring in a Desiccating Alkaline Maar Lake (Central Mexico)

Journal of Eukaryotic Microbiology, Volume 73, Issue 6, November/December 2026.
ABSTRACT Microeukaryotes are important components of microbial food webs in saline and alkaline lakes, yet their diversity and distribution across distinct microhabitats remain poorly understood. We characterized microeukaryotic communities associated with microbialites, microbial mats, hypersaline waters, and sediments in the desiccating maar lake ...

Stranded Assets

Colloquy: Text, Theory, Critique, 2018
The glass viewing platform jutted out over the lip of the crater. Roberta’s hands clenched around the rail as she fought a swirl of vertigo. The massive gouge yawned beneath her, stepped sides dripping with greenery cut through with walking trails.

Sampling genetic diversity in the sympatrically and allopatrically speciating Midas cichlid species complex over a 16 year time series

BMC Evolutionary Biology, 2007
Background Speciation often occurs in complex or uncertain temporal and spatial contexts. Processes such as reinforcement, allopatric divergence, and assortative mating can proceed at different rates and with different strengths as populations diverge ...

Whump, Slosh, Slosh, Slosh—Filling the Crater That Did in the Dinosaurs

AGU Advances, 2020
Drilling into the Chicxulub crater (Yucatan, Mexico) reveals the dramatic aftermath of the dinosaur‐killing meteorite impact. Previous views of this event have mainly come from places well away from Ground Zero, where we see the extinction of ~70% of ...

High‐Resolution Temperature and Precipitation Variability in Northeast Asia Since the Last Glacial Maximum Recorded in an Annually Laminated Maar Lake

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.
Abstract Temperature and precipitation variability in monsoonal Asia is central to understanding regional climate dynamics and global teleconnections. How post‐LGM warming and hydroclimate change unfolded in Northeast Asia, and how they were linked to external forcing, remain poorly constrained.

Shallow Poroelastic Hydrothermal Deformation at Changbaishan Volcano Before the 2020 Unrest Revealed by Sentinel‐1 InSAR Time Series

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Ground deformation of dormant volcanoes provides critical insights into subsurface processes and potential hazards. Here we present Sentinel‐1 Interferometric Synthetic Aperture Radar (InSAR) time series (2015–2020) for Changbaishan volcano, the largest intraplate volcanic system in East Asia. We detect persistent subsidence of up to 3.5 mm/yr
