Scientific Reports, 2018 The distance-dependent coseismic and postseismic displacements produced by the 2011 MW9.0 Tohoku-Oki megathrust earthquake caused medium weakening and stress perturbation in the crust around the Korean Peninsula, increasing the seismicity with successive

A Seismically Active Shear Zone in the Uppermost Mantle Beneath the Canadian Rockies
Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.Abstract Continental mantle earthquakes are uncommon but hold important clues for understanding lithospheric rheology. Few of these earthquakes (<10) have been documented in western North America, though it is likely more exist owing to difficulties in resolving focal depth for small earthquakes.

Local earthquakes Recorded at Syowa Station, Antarctica
Antarctic Record, 1997 The Japanese Antarctic Station Syowa (69°S, 39°E) is located at the edge of the East Antarctic Shield area. Seismic observations at Syowa Station were started in 1959.

The April 2017 Mw6.5 Botswana Earthquake: An Intraplate Event Triggered by Deep Fluids
Geophysical Research Letters, 2018 Large earthquakes in stable continental regions remain puzzling as; unlike at plate boundaries, they do not result from the local buildup of strain driven by plate tectonics. The 2017 Mw6.5, Bostwana normal faulting earthquake occurred in a region devoid

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.Abstract In 2022–2023, three local‐magnitude (ML) 4.8–5.6 earthquakes shook the Peace River oilsands area of Alberta, Canada. Previous studies statistically linked the seismicity to nearby disposal activities but lacked in‐depth investigation into triggering mechanisms, including subsurface fluid migration and earthquake interaction.

Improving the Knowledge on Seismogenic Sources in the Lower Tagus Valley for Seismic Hazard Purposes [PDF]
, 2012 The Lower Tagus Valley, that includes the metropolitan area of Lisbon, has been struck by several earthquakes which produced significant material damage and loss of lives. Their exact location remains unknown.

Earthquake source mechanisms and plate tectonics [PDF]
, 1979 This review and the accompanying references will be concerned mainly with earthquake source studies pertinent to plate tectonics. Studies on geological problems, lithospheric flexure and mantle convection are discussed in other reviews in this volume.

Ancient Faults Amplify Intraplate Earthquakes
Eos, 2019 A comparison of deformation rates from Canada’s Saint Lawrence Valley offers compelling evidence that strain in the region is concentrated along ancient structures from previous tectonic cycles.

Distinguishing intraplate from megathrust earthquakes using lacustrine turbidites [PDF]
Geology, 2019 Subduction zone seismicity arises from megathrust, crustal, and intraslab earthquakes, and understanding the recurrence patterns of each type is crucial for hazard assessments. Lake sediments can record earthquakes from all three seismogenic sources. Here, we studied the turbidite record of Lo Encanado, an Andean lake located in central Chile.

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.Abstract The structure and properties of mature upper oceanic plates may evolve through mechanisms such as magmatism, hydrothermal circulation, and faulting. However, high‐resolution constraints, especially those involving both P‐ and S‐waves, remain scarce, limiting our ability to detect these processes and assess their impacts on crustal properties ...
