Shallow Tectonic Tremors Reveal the Beginning of the Slab Window at the Chilean Triple Junction

open access: yesGeophysical Research Letters, Volume 52, Issue 14, 28 July 2025.
Abstract The subduction of active spreading centers is an unusual phenomenon along subduction zones. In southern Chile, the Nazca‐Antarctic spreading system (Chile Rise) subducts beneath the South America plate at the Chile Triple Junction (CTJ), forming the Patagonian slab window.

Dispersion of Lamb Waves From the 2022 Hunga Tonga–Hunga Ha'apai Volcanic Eruption Reveals Coupling Between Lower and Upper Atmospheric Layers

open access: yesGeophysical Research Letters, Volume 52, Issue 14, 28 July 2025.
Abstract Atmospheric Lamb waveforms are useful for reconstructing large air events, but the propagation of Lamb waves is significantly affected by varying atmospheric conditions. The detailed dispersion of Lamb waves remains vague due to lack of data, but also to simplifications inherent in existing models.

Rupture Process of the Mw7.0 December 5, 2024 Offshore Cape Mendocino Earthquake

open access: yesGeophysical Research Letters, Volume 52, Issue 14, 28 July 2025.
Abstract The Mw7.0 December 5, 2024 Offshore Cape Mendocino earthquake ruptured a ∼60 ${\sim} 60$ km long portion of the east‐west trending Mendocino fault zone (MFZ). In order to clarify the rupture process, we assemble three‐component seismograms from regional seismic stations, horizontal coseismic displacement vectors derived from Global Navigation ...

Ambient Noise Imaging of Western Europe From Combining Linear SOLA Backus–Gilbert Inference and Non‐Linear Probabilistic Approaches

open access: yesGeophysical Research Letters, Volume 52, Issue 14, 28 July 2025.
Abstract We present a new method for ambient noise tomography, which provides robust velocity images accompanied with meaningful estimates of local resolution and uncertainty. We use the Subtractive Optimally Localized Averages (SOLA) Backus–Gilbert inference method to determine surface wave velocities as local (unbiased) averages of the “true” model ...
