Tephra fall impacts to buildings: the 2017–2018 Manaro Voui eruption, Vanuatu
Frontiers in Earth ScienceBuilding damage from tephra falls can have a substantial impact on exposed communities around erupting volcanoes. There are limited empirical studies of tephra fall impacts on buildings, with none on tephra falls impacting traditional thatched timber ...

Geochemistry, Geophysics, Geosystems, 2018 Aluto is a silicic volcano in central Ethiopia, flanked by two large population centers and home to an expanding geothermal power plant. Here we present data from two lake sediment cores sampled 12 and 25 km from the volcano, which record at least 24 ...

Boreas, EarlyView.The glacierized Valle Frías in Northern Patagonia is one of the best‐studied valleys in South America and includes varved sediments from Lago Frías. We complement this lacustrine record with a high‐resolution documentation of varve counts and their composition.

Earth, Planets and SpaceThe profile of tephra concentration along a volcanic plume (i.e., the tephra segregation profile) is an important source parameter for the simulation of tephra transport and deposition and thus for the tephra sedimentation load.

QuaternaryThe analysis of tephra layers in maar lake sediments of the Eifel shows 14 well-visible tephra during the last glacial cycle from the Holocene to the Eemian (0–130,000 yr b2k).

Sustained Livestock Grazing Enhances Soil Organic Carbon Storage in Sub‐Arctic Grassland
Global Change Biology Communications, Volume 1, Issue 4, December 2026.We studied long‐term effects of grazing cessation on 34 grassland and heathland sites in Iceland. Grazing cessation was associated with lower SOC, nitrogen and root carbon in the top 10 cm of soil providing evidence for enhanced SOC in grazed land, showing that grazing is a climate change mitigation strategy.

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.Abstract Magnetic minerals preserved in marginal‐sea sediments can serve as distinct fingerprints for unraveling paleoenvironmental evolution. However, the forcing mechanisms that govern the transport and accumulation of individual magnetic minerals at orbital timescales remain poorly constrained.

Pre‐Eruptive Volatiles and Magma Storage Depth for the 2018 Eruption at Mount Veniaminof, Alaska
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.Abstract Mount Veniaminof is a frequently active, open‐system arc volcano on the Alaska Peninsula, part of the Alaska‐Aleutian arc. Mount Veniaminof's September–December 2018 eruption began with small lava flows and culminated in a larger explosive event in November that produced a 450 km long continuous ash plume—one of the volcano's most significant ...

Sedimentology, Volume 73, Issue 6, Page 2488-2518, October 2026.ABSTRACT Previous studies have documented genetic divergence within the last few million years between northern and southern populations of terrestrial plants and animals along the Baja California peninsula, with many studies hypothesising that the divergence is due to an ancient seaway that crossed the central peninsula and created a physical barrier ...
