Suppression of Sub‐Salt Folding in Cover Sequences by Lateral Flow of Evaporites

Basin Research, Volume 38, Issue 5, September‐October 2026.
Schematic tectonic evolution of the Northern Levant from the Messinian: (A) after an initial folding phase and during deposition of the Messinian evaporites, (B) the terminus of the Messinian and deposition of the Nahr Me, and (C) a second folding phase during the Pliocene‐Pleistocene, inducing evaporite flow.

Earthquake Seismicity Reveals the Location and Significance of the Shona Mantle Plume in the South Atlantic Ocean

Geophysical Research Letters
The South Atlantic Ocean hosts several well‐studied volcanic ridges and seamount chains, but the origin of their associated mantle plumes is debated.

An Inflating Upper Mantle Magma Reservoir Beneath the Tip of the Condor Seamount, Azores Revealed by Rapid‐Response Ocean‐Bottom‐Seismometer Data

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Condor Seamount is among the most seismically active regions on the Azores Plateau. In December 2019, an earthquake crisis occurred at the tip of the seamount, which was strongly felt on nearby islands. Two months after the peak of the crisis, we deployed a local network of five ocean‐bottom seismometers around the seamount, recording ...

Mid‐Ocean Ridge (MOR) Ash Dispersal on Axial Seamount, Juan de Fuca Ridge

Geochemistry, Geophysics, Geosystems
Rare eruption of primitive normal mid‐ocean ridge basalt (N‐MORB) magma (∼9.5 wt% MgO) on the summit of Axial Seamount generated abundant ash that was dispersed for several km.

Dike‐Induced Earthquakes as Probes of the Local Stress Field Prior to the 1998 Eruption of the Piton de la Fournaise Volcano, La Réunion

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Volcano‐tectonic (VT) earthquakes generated during dike propagation provide useful constraints on stress changes in volcanic systems. During the 1998 pre‐eruptive unrest at Piton de la Fournaise, ∼600 VT earthquakes were recorded. Using manually picked first‐motion polarities and corrected station metadata, we calculated more than 400 high ...

Post Eruption inflation of the East Pacific Rise at 9°50′ N

Geochemistry, Geophysics, Geosystems, 2014
In June 2008, we installed a geodetic network at 9°50′ N on the East Pacific Rise to track the long‐term movement of magma following the 2005/6 eruption. This network consists of 10 concrete benchmarks stretching from the ridge to 9 km off‐axis.

The geodynamics of plume-influenced mid-ocean ridges: insights from the Foundation Segment of the Pacific-Antarctic Ridge

Frontiers in Earth Science
The intersection of the Foundation Plume with the Pacific-Antarctic Ridge is a key location in global geodynamics where a mantle plume is approached by and interacting with a fast-spreading mid-ocean ridge.
