Estimates of the Temperature and Melting Conditions of the Carpathian‐Pannonian Upper Mantle From Volcanism and Seismology

Geochemistry, Geophysics, Geosystems, 2020
What drives the formation of basaltic melts beneath intraplate volcanoes not associated with extensive thermal anomalies or lithospheric extension? Detailed constraints on the melting conditions and source region are imperative to resolve this question ...

Glacial rebound causes intraplate volcanism off South Greenland

, 2011
Plate tectonic mechanisms explain most of the dominant types of volcanism. Intraplate volcanism has been attributed to hot spots associated with mantle plumes, though alternative explanations have been proposed for settings not fed by plumes.

The depth geodynamic state and its correlation with the surface geological and geophysical parameters along the sublatitudinal profile of Eurasia

Геодинамика и тектонофизика, 2019
A cross‐sections of longitudinal (P) and transverse (S) wave anomalies (attribute δ(VP/VS)) is constructed along the sublatitudinal profile from the Atlantic Ocean to the Pacific Ocean across the regions of the latest Eurasian volcanism. It is correlated

An Overview of Tsunami Hazards in the Southwest Pacific Ocean

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
The southwest Pacific region is geologically complex and exhibits all the principal causes of tsunami generation. While contemporary events and historical catalogs indicate that trans‐Pacific tsunamis have affected this area (∼18% of tsunamis reported globally), it is unique in that a large part of the tsunami effects over the ∼200‐year historical ...

Earthquake Rate Variability in the Auckland Volcanic Field Within a Long‐Duration Self‐Consistent Earthquake Catalogue

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
Eruptions in the Auckland Volcanic Field in Aotearoa New Zealand have not occurred since seismic monitoring began in Aotearoa New Zealand, but it is generally presumed that future eruptions from the Auckland Volcanic Field will be preceded by elevated rates of seismicity.

Origin of Alkaline Basaltic Intrusive Rocks in an Exhumed Accretionary Complex: Implications for Past Petit‐Spot Volcanism in the Ocean

Geochemistry, Geophysics, Geosystems, 2023
Accreted basaltic rocks are expected to provide information on intraplate volcanism in the oceans. Basaltic rocks, originating from mid‐ocean ridges, plateaus, and seamounts, have been reported from exhumed accretionary complexes. However, basaltic rocks

Hafnium isotopic variations in East Atlantic intraplate volcanism [PDF]

Contributions to Mineralogy and Petrology, 2010
The broad belt of intraplate volcanism in the East Atlantic between 25° and 37° N is proposed to have formed by two adjacent hotspot tracks (the Madeira and Canary tracks) that possess systematically different isotopic signatures reflecting different mantle source compositions.

Pliocene adakite-like accent of andesites and dacites from the Orlov volcanic field (Sakhalin Island)

Геосистемы переходных зон, 2021
Adakite-like geochemical signature (high Sr/Y ratio at a low Y concentration) is recognized in andesites and dacites, associated with intraplate basalts in the Orlov volcanic field of Sakhalin Island.

Mantle xenoliths in young intraplate volcanism: The mantle beneath the Arabian plate

, 2022
Mantle-derived xenoliths occurrence in volcanic rocks provide an opportunity to study deep mantle structures in specific geological settings. As direct samples of the mantle, xenoliths are information carriers of the lithospheric mantle nature at the ...

Aerial and Space‐Borne Seismology on Venus: Viability and Design Implications for Future Missions

Earth and Space Science, Volume 13, Issue 6, June 2026.
Abstract Venus' evolution remains a mystery because of the lack of in situ geophysical data to constrain its interior structure. Recently‐selected planetary missions VERITAS (NASA), DAVINCI+ (NASA), and EnVision (ESA) will investigate the planet's interior, surface, and atmospheric chemistry.
