Seismotectonics of the Explorer region [PDF]

Journal of Geophysical Research: Solid Earth, 2002
The Explorer region offshore western Canada is a tectonically complex area surrounded by the Pacific, North America, and Juan de Fuca plates. Existing tectonic models for the region differ fundamentally. Proposed plate configurations range from multiple independent plate fragments to an Explorer plate now fused to North America along the continental ...

Fluid‐Induced Fault Reactivations in Strike‐Slip Regimes: Temporal Constraints From GNSS and Seismological Analysis in the Peloritani Mts and Aeolian Archipelago (Central Mediterranean)

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 1, January 2026.
Abstract Fluids can modify the mechanical properties of rocks, including shear strength and strain behavior. We investigate the timing and magnitude of seismic events during fault motion in strike–slip systems across the Peloritani Mountains (northeastern Sicily) and Aeolian Archipelago using GNSS and seismological data analysis.

Inelastic Dilatancy as a Mechanism for Coseismic Fluid Depressurization of a Shallow Fault Zone

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract Hydrologic observations and experimental studies indicate that inelastic dilation from coseismic fault damage can cause substantial pore pressure reduction, yet most near‐fault hydromechanical models ignore such inelastic effects. Here, we present a 3‐D groundwater flow model incorporating the effects of inelastic dilation based on an ...

Beachrock formation influenced by co‐seismic deformation and relative sea‐level changes during the Holocene near the Gulf of Saros, Türkiye (NE Aegean Sea)

Boreas, Volume 55, Issue 1, Page 231-257, January 2026.
This is the first proof of beachrock found on the nearshore of the Gulf of Saros. Beachrock generation was influenced by tectonic activity, geomorphological processes, and sedimentation. The Late Holocene beachrock deposits were altered by co‐seismic deformation.

Seismotectonics of Malatya Fault, Eastern Turkey

Open Geosciences, 2019
AbstractTurkey is located in a seismically active region with a complex tectonic history. In order to perform seismic risk assessment precisely, major fault zones (North Anatolian Fault Zone and East Anatolian Fault Zone) that are well defined are monitored continuously.

High‐Density Seismic Network for Improved Tomographic Imaging of the Ecuadorian Forearc: Slip Mode Controlled by In Situ Material Heterogeneity

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract Large subduction earthquakes often occur along the Ecuadorian margin. Following the 2016 Pedernales megathrust earthquake (Mw 7.8), a temporary network of 82 stations recorded its aftershocks. Data from this international response and the permanent network run by IG‐EPN showed that subducted seafloor topography, accreted terranes, and ...

The recent 2007 Portugal earthquake (Mw=6.1) in the seismotectonic context of the SW Atlantic area [PDF]

, 2007
An event of magnitude Mw 6.1(EMSC) occurred on 12/02/2007 at 10:35 UTC off coast of South-Western Portugal. The earthquake had its epicentre in the eastern Horseshoe Abyssal Plain, at 175 km South-West of San Vicente Cape (Figure 1).

Quaternary rupture of a crustal fault beneath Victoria, British Columbia, Canada [PDF]

, 2017
The seismic potential of crustal faults within the forearc of the northern Cascadia subduction zone in British Columbia has remained elusive, despite the recognition of recent seismic activity on nearby fault systems within the Juan de Fuca Strait.

Influence of Structural Maturity on the Rupture Morphology of the Northern Alpine Fault, Aotearoa New Zealand

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract The Alpine Fault (AF) in Aotearoa New Zealand is a fast‐slipping plate boundary fault late in its seismic cycle that presents a major source of seismic hazard. Past earthquakes have created a structural‐geomorphic record of surface ruptures that we map and analyze for the northern AF using 1,000 km2 ${\text{km}}^{2}$ of Light Detection and ...

Review of geological and seismotectonic investigations related to 1998 Mw5.6 and 2004 Mw5.2 earthquakes in Krn Mountains to 1998 Mw5.6 and 2004 Mw5.2 earthquakes in Krn Mountains

Geologija, 2019
A review of geological and seismotectonic investigations conducted in the two decades after the 12 April 1998 earthquake in Krn Mountains, according to its magnitude the strongest earthquake in Slovenia in the 20th century, is given.
