Seismicity, Repeating Earthquakes, and Tomographic Imaging of the Blanco Transform Fault System, Northeast Pacific

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract The Blanco transform fault system (BTFS) represents an evolving transform plate boundary in the Northeast Pacific Ocean. Its seismic behavior was captured with a dense network of 54 ocean‐bottom seismometers (OBS) operated for 1 year. We created a high‐resolution earthquake catalog based on different machine‐learning onset pickers.

Rayleigh Waves From OHANA OBSs in the Northeast Pacific Ocean Reveal Low Deep Shear Velocities and Pervasive Azimuthal Anisotropy

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract The 2021–2023 OHANA ocean‐bottom seismometer deployment in the northeast Pacific Ocean provides a rich data set for seismic studies to explore the crust, lithosphere and asthenosphere in a 600 km wide region about 1,500 km northeast of Hawaii, west of the Moonless Mountains. The study area covers mainly 40‐to‐55 Myr‐old Pacific lithosphere.

A Hierarchical Bayesian Model for the Global Holocene Geomagnetic Field

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract We present a hierarchical Bayesian model of the global geomagnetic field for the last 8,000 years. The model is built solely with thermoremanent records, which include archeomagnetic and volcanic data. Building upon previous work, this model includes fewer approximations and treats model hyperparameters as probabilistic variables.

Stress field rotation or block rotation: An example from the Lake Mead fault system [PDF]

open access: yes
The Coulomb criterion, as applied by Anderson (1951), has been widely used as the basis for inferring paleostresses from in situ fault slip data, assuming that faults are optimally oriented relative to the tectonic stress direction.

Coupled surface process and tectonic modelling of extension-inversion tectonics in the Pyrenees

open access: yes, 2014
The research presented in this thesis was conducted at the Department of Earth Science, University of Bergen (Norway), and in parallel at the Institute of Earth Sciences, Joseph Fourier University (Grenoble, France) under the supervision of Prof. Ritske Huismans, Prof. Peter van der Beek and Prof. Haakon Fossen.

Assessing Deposit‐Derived Pyroclastic Flow Hazard at Stromboli (Italy): 1. Reconstruction of the Dynamics of the 11 September 1930 Event

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract Stromboli volcano (Italy) is known for its persistent explosive activity punctuated by more energetic explosions called paroxysms. During paroxysms, pyroclastic density currents, triggered by the gravitational instability of hot pyroclastic deposits, can occur.
