Geodetic Observations and Seismogenic Structures of the 2025 Mw 7.0 Dingri Earthquake: The Largest Normal Faulting Event in the Southern Tibet Rift

Remote Sensing
The Mw 7.0 Dingri earthquake, which occurred on 7 January 2025, occurred at the southern end of the Xainza-Dinggyê Fault Zone within the South Tibet Rift (STR) system, in the Dengmecuo graben.

Fault activity studies in the Lower Tagus valley and Lisbon region using geophysical data [PDF]

, 2018
he Metropolitan Area of Lisbon and the Lower Tagus Valley (LTV) region are located in central Portugal and inhabited by nearly 4 million people. The region has suffered throughout its history the effect of destructive earthquakes caused by hidden faults,

Subparallel thrust and normal faulting in Albania and the roles of gravitational potential energy and rheology contrasts in mountain belts [PDF]

, 2009
The active tectonics of Albania and surrounding regions, on the eastern margin of the Adriatic Sea, is characterized by subparallel thrust and normal faulting which, we suggest, is likely to be related to gravitational potential energy contrasts between ...

Retrospective earthquake spatial forecasting: magnetotelluric insights into fluid-driven intraplate seismicity in northern Thailand from 1994 to 2024

Earth, Planets and Space
This study investigates the role of crustal fluids in the seismogenesis of three significant intraplate earthquakes in northern Thailand: the 1994 Phan, 2014 Mae Lao, and the unexpected 2019 Wang Nuea events, which occurred after a decade of seismic ...

Role of Intraplate Strike-Slip Earthquakes in Accommodating Convergence Across the Eastern Himalayan Plate Boundary System [PDF]

Lithosphere
North-East India, at the eastern extremity of the Himalaya, is one of the most rapidly deforming intraplate regions. The tectonics of this region is shaped by oblique convergence between two nearly perpendicular plate boundaries of the Eastern Himalaya ...

The 2001 M_w 7.6 Bhuj earthquake, low fault friction, and the crustal support of plate driving forces in India [PDF]

, 2011
We present a source model for the 2001 M_w 7.6 Bhuj earthquake of northwest India. The slip distribution suggests a high stress drop (~35 MPa) and, together with the depth distribution of aftershocks, that the entire crust is seismogenic. We suggest that

Imaging the Low Dip Onset of the Gibraltar Arc Subduction in the Gulf of Cádiz Using OBS Receiver Functions

Geophysical Research Letters, Volume 52, Issue 23, 16 December 2025.
Abstract Using P and S‐wave receiver function analysis we investigate the lithospheric structure in the Gulf of Cádiz through a combination of ocean‐bottom seismometers and onshore seismic stations located in southwest Iberia and northwest Africa. By applying common conversion point migration with custom earth models accounting for the marine sediment ...

Intraplate seismicity in Canada: a graph theoretic approach to data analysis and interpretation [PDF]

Nonlinear Processes in Geophysics, 2010
Intraplate seismicity occurs in central and northern Canada, but the underlying origin and dynamics remain poorly understood. Here, we apply a graph theoretic approach to characterize the statistical structure of spatiotemporal clustering exhibited by ...

Scaling differences between large interplate and intraplate earthquakes [PDF]

, 1986
A study of large intraplate earthquakes with well-determined source parameters shows that these earthquakes obey a scaling law similar to large interplate earthquakes, in which M_0 ∝ L^2 or u = αL, where L is rupture length and u is slip.

Thick Underplating and Buoyancy of the Bermuda Swell

Geophysical Research Letters, Volume 52, Issue 23, 16 December 2025.
Abstract Bermuda is an intraplate ocean swell that does not conform to traditional mantle plume theory. Unlike other prominent bathymetric swells, such as Hawaii, it lacks age‐progressive volcanism, a deeply rooted mantle plume, and modern volcanism. High‐frequency receiver‐function imaging of the shallow lithosphere beneath the Bermuda swell reveals ...
