Medieval Irish chronicles reveal persistent volcanic forcing of severe winter cold events, 431–1649 CE

Environmental Research Letters, 2013
Explosive volcanism resulting in stratospheric injection of sulfate aerosol is a major driver of regional to global climatic variability on interannual and longer timescales. However, much of our knowledge of the climatic impact of volcanism derives from

Impacts of Volcanic Emissions on the Global Biogeochemical Mercury Cycle: Insights From Satellite Observations and Chemical Transport Modeling

Geophysical Research Letters, 2023
Volcanism is the largest natural source of mercury (Hg) to the biosphere. However, past Hg emission estimates have varied by three orders of magnitude. Here, we present an updated central estimate and interquartile range (232 Mg a−1; IQR: 170–336 Mg a−1)

An Integrated Geologic Map of the Rembrandt Basin, on Mercury, as a Starting Point for Stratigraphic Analysis

Remote Sensing, 2020
Planetary geologic maps are usually carried out following a morpho-stratigraphic approach where morphology is the dominant character guiding the remote sensing image interpretation.

The Atlas of Morocco: A Plume‐Assisted Orogeny

Geochemistry, Geophysics, Geosystems, 2023
We explore the connections between crustal shortening, volcanism, and mantle dynamics in the Atlas of Morocco. In response to compressional forces and strain localization, this intraplate orogen has evolved far from convergent plate margins.

The Volcanic Landscapes of the Ancient Hunter-Gatherers of the Atacama Desert Through Their Lithic Remains

Frontiers in Earth Science, 2022
Since ancient times Andean societies have formed an intimate relationship with volcanoes, the beginnings of which can be traced right back to the initial peopling of the region.

Late Cenozoic intraplate volcanism as a trigger for hydrothermal venting in the Arctic southwestern Eurasia Basin

Communications Earth & Environment
Intraplate volcanism has occurred for the last 35 million years within Northeast Atlantic and Arctic margins, including the western Barents Sea, Svalbard, and northern Greenland. Earlier studies have suggested that some of this volcanism might be sourced

Distribution and morphology of present-day glaciers on Kamchatka

Лëд и снег, 2020
The current glacierization of the Kamchatka Peninsula includes 643 glaciers with a total area 769.48±48.34 km2. A variety of combinations of macro-relief factors, climate and volcanism caused irregular distribution of glaciers on the Peninsula, as well ...
