Microgravity Measurements Spanning 2019–2022 Indicate No Change in Magma Supply or Storage During Kīlauea's Reawakening

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract After more than 2 years of quiescence following its major 2018 flank lava effusion and summit caldera collapse, Kīlauea, Hawaiʻi, returned to frequent eruptive activity in late 2020. Microgravity measurements from the summit region in 2019 and 2022 span this reawakening and indicate a gravity increase of up to hundreds of microgals near the ...

Episodic Seismicity Bursts Driven by Magma Intrusion During the 2025 Santorini‐Amorgos Seismic Crisis

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract The 2025 Santorini–Amorgos seismic crisis in Greece had an exceptionally large number and sustained rate of moderate‐sized earthquakes. We used a machine‐learning‐based earthquake monitoring workflow to detect and relocate 66,109 earthquakes and interpret the results in the context of global analogs.

High‐Resolution Body‐Wave Tomography of Kı̄lauea's Summit Magma Storage System From a Dense Passive and Active Source Experiment

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract Imaging magma storage beneath active calderas requires resolving crustal structure at scales comparable to those of individual reservoirs. To identify potential reservoirs beneath Kı̄lauea, Hawai'i, we conducted a hybrid seismic experiment at its summit for 37 days in 2023 that combined more than 1,800 three‐component nodal seismometers with ...

Air–Water Greenhouse Gases Exchange in Surface Waters of Deception Island (South Shetland Archipelago, Antarctica): Assessment of Drivers of Spatial Variability

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 10, October 2026.
Abstract Greenhouse gases (GHGs) such as Carbon Dioxide (CO2), Methane (CH4), and Nitrous Oxide (N2O) play critical roles in global climate change. CO2 dominates due to its high concentration and long atmospheric lifetime, while CH4 and N2O also exert strong heat‐trapping effects despite shorter residence times. Deception Island, in the Southern Ocean,

Magma Channeling and Crustal Structure of a STEP Fault From Integrated Geological and Geophysical Data: The Central Aeolian Volcanoes (Southern Tyrrhenian Sea)

Tectonics, Volume 45, Issue 10, October 2026.
Abstract Arc volcanism is commonly interpreted as the surface expression of subduction‐related magmatism and its spatial organization is often controlled by lithospheric structures. In arc‐back‐arc systems, slab retreat may promote the transition from compression to extension and the development of Subduction‐Transform Edge Propagator (STEP) faults ...

Dispersal, source and glass chemistry of a third tephra unit within Iceland's Settlement Layer

Boreas, Volume 55, Issue 4, Page 1143-1159, October 2026.
Tephra layers may be studied to understand the dynamics and sequence of past explosive volcanism. In Iceland, the distinctive Settlement Layer (AD ~877) underlies almost all archaeological evidence for the Norse Settlement and is preserved in soils across Iceland and as cryptotephra overseas.

Evidence for the continental origin of Pliocene deposits in the central Baja California peninsula, Mexico, and implications for controls on biodiversity

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 ...
