Basin Research, Volume 38, Issue 3, May–June 2026.2D seismic and well data reveal multi‐phase basin filling in the Whatcom Sub‐Basin shaped by syn‐depositional tectonism. An Eocene transition from forearc basin to forearc depression corresponds to decreasing normal‐fault density and throw, both upsection and eastward. Paleogene–Neogene strata are the best CO2 storage targets.

Bridging the gap between low-frequency and very-low-frequency earthquakes
Earth, Planets and Space, 2020 Slow earthquakes that are observed in the > 1 Hz frequency band are called tectonic tremor or low-frequency earthquakes (LFEs) and those in the 0.01–0.10 Hz band are called very-low-frequency earthquakes (VLFEs).

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract Understanding the cause of spatial variations in seismicity is crucial for comprehending the physics governing earthquake activity. Off Iwate, in the northern Japan Trench subduction zone, the plate boundary can be divided into three distinct zones based on depth‐dependent slip regimes: the slow earthquake, asperity, and stable creeping zones.

A stochastic approach to reconstruction of faults in elastic half space [PDF]
, 2018 We introduce in this study an algorithm for the imaging of faults and of slip fields on those faults. The physics of this problem are modeled using the equations of linear elasticity.

Shallow Creep in the Leaky Stress Shadow of Locked Zones of Subduction Megathrust
Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract In some subduction zones such as Nankai, creeping of the shallow part of the megathrust in the stress shadow of deeper locked zones is detected by seafloor geodetic measurements and/or reflected by slow earthquakes (SEQs). Here we explain that shallow creep occurs in the stress shadow for two reasons: (a) prolonged afterslip and (b) a leaky ...

Seismic risk management of existing reinforced concrete buildings in the Cascadia subduction zone [PDF]
, 2017 Through evolution of building design codes in active seismic regions, life safety performance limit state has been met. Unacceptably high economic loss during the 1994 Northridge and 1995 Kobe earthquakes, however, has brought forward a new design ...

The Detection of Transient Subduction Zone Interface Properties Using Teleseismic Data
Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract The physical properties of subduction zone interfaces govern the transition between stable aseismic slip, episodic slow slip events (SSEs), and large earthquakes. Ultraslow velocity layers (USVLs) along the megathrust are commonly interpreted as indicators of elevated pore‐fluid pressures that promote slow slip, but their temporal variability ...

Shoreline crossing Moho geometry of the Cascadia slab: CascadiaMoho1.0
SeismicaAccurate characterization of subducting slab geometry is fundamental to understanding the distribution of earthquakes, the dynamics of arc volcanism, and the assessment of seismic hazards.
