Aftershock Spatiotemporal Activity and Coseismic Slip Model of the 2022 Mw 6.7 Luding Earthquake: Fault Geometry Structures and Complex Rupture Characteristics

Remote Sensing
On 5 September 2022, the moment magnitude (Mw) 6.7 Luding earthquake struck in the Xianshuihe Fault system on the eastern edge of the Tibet Plateau, illuminating the seismic gap in the Moxi segment.

The 2018 Hokkaido Eastern Iburi earthquake (M JMA = 6.7) was triggered by a strike-slip faulting in a stepover segment: insights from the aftershock distribution and the focal mechanism solution of the main shock

Earth, Planets and Space, 2019
The Hokkaido Eastern Iburi earthquake (M JMA = 6.7) occurred on September 6, 2018, in the Hokkaido corner region where the Kurile and northeastern Japan island arcs meet.

Deep ductile shear localization facilitates near-orthogonal strike-slip faulting in a thin brittle lithosphere [PDF]

, 2020
Some active fault systems comprise near-orthogonal conjugate strike-slip faults, as highlighted by the 2019 Ridgecrest and the 2012 Indian Ocean earthquake sequences.

Intraplate Triggered Earthquakes: Observations and Interpretation

Bulletin of the Seismological Society of America, 2003
We present evidence that at least two of the three 1811-1812 New Madrid, central United States, mainshocks and the 1886 Charleston, South Carolina, earthquake triggered earthquakes at regional distances. In addition to previously pub- lished evidence for triggered earthquakes in the northern Kentucky/southern Ohio region in 1812, we present evidence ...

Use of Macroseismic Intensity Data to Validate a Regionally Adjustable Ground Motion Prediction Model

Geosciences, 2019
In low-to-moderate seismicity (intraplate) regions where locally recorded strong motion data are too scare for conventional regression analysis, stochastic simulations based on seismological modelling have often been used to predict ground motions of ...

Selection of earthquake ground motion accelerograms for the continental margin of Southeastern Brazil

Dyna, 2021
Brazil is in an intraplate area of low to moderate seismicity, this means that few or no records of strong ground motions are available. Part of the site response analysis and seismic design of structures require the use of acceleration time-histories ...

Elevated Asthenospheric Temperature Driving the Partial Melting of Enriched Lithospheric Mantle Feeding the DM‐EM1 Mixing‐Type Magmatism of the Jingpohu Volcano in Eastern NE China: Evidence From Teleseismic P‐Wave Attenuation

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract The origin of a binary‐mixing of DM and EM1 sources for the Cenozoic intraplate volcanism in eastern Northeast China is yet unclear. Seismic attenuation imaging is a tool that can shed light on this question. Here we present the first map of teleseismic P‐wave attenuation across Northeast China.

The 2016 Kumamoto Earthquakes: Cascading Geological Hazards and Compounding Risks

Frontiers in Built Environment, 2016
A sequence of two strike-slip earthquakes occurred on 14 and 16 April 2016 in the intraplate region of Kyushu Island, Japan, apart from subduction zones, and caused significant damage and disruption to the Kumamoto region.

Geomorphic signal of active faulting at the northern edge of Lut Block. Insights on the kinematic scenario of Central Iran [PDF]

, 2016
Recent works documented Neogene to Quaternary dextral strike-slip tectonics along the Kuh-e-Sarhangi and Kuh-e-Faghan intraplate strike-slip faults at the northern edge of the Lut Block of Central Iran, previously thought to be dominated by sinistral ...
