Interseismic coupling and seismic potential along the Central Andes subduction zone [PDF]

open access: yes, 2011
We use about two decades of geodetic measurements to characterize interseismic strain build up along the Central Andes subduction zone from Lima, Peru, to Antofagasta, Chile.

High‐Precision Aftershock Distribution Highlights the Complex Fault Geometry of the 2024 Mw 7.5 Noto Peninsula Earthquake

open access: yesGeophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract We deployed 30 temporary seismic stations around the source region of the 2024 Mw 7.5 Noto Peninsula earthquake to investigate the relationship between mainshock rupture and fault geometry. Using machine learning techniques, we detected and precisely located 46,252 aftershocks, revealing several fault planes corresponding to active faults ...

Refined Coseismic Slip and Afterslip Distributions of the 2021 Mw 6.1 Yangbi Earthquake Based on GNSS and InSAR Observations

open access: yesRemote Sensing
On 21 May 2021, an Mw 6.1 earthquake occurred in Yangbi County, Dali Bai Autonomous Prefecture, Yunnan Province, with the epicenter located in an unmapped blind fault approximately 7 km west of the Weixi-Qiaohou fault (WQF) on the southeastern margin of ...

High‐Resolution Satellite Imagery Mapping of the Surface Rupture and Slip Distribution of the Sagaing Fault in the 28 March 2025 Mw 7.7 Earthquake, Myanmar

open access: yesGeophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract On 28 March 2025, a Mw 7.7 earthquake occurred on the Sagaing Fault in Myanmar. Security constraints prevented timely field investigations on its surface rupture, hindering analysis of seismotectonics and rupture dynamics. Using high‐resolution satellite imagery, we mapped a ∼420 km surface rupture and measured 540 dextral offsets, revealing ...

Fault geometry and rupture speed as controls on off-fault deformation in the 2023 Turkey-Syria earthquakes

open access: yesCommunications Earth & Environment
Coseismic off-fault deformation (OFD) measurements provide crucial insight into fault deformation behavior and shallow faulting damage. Although kinematic and dynamic characteristics of the causative faults associated with the 2023 Turkey-Syria ...

Asperities and barriers on the seismogenic zone in North Chile: state-of-the-art after the 2007 Mw 7.7 Tocopilla earthquake inferred by GPS and InSAR data [PDF]

open access: yes, 2010
The Mw 7.7 2007 November 14 earthquake had an epicentre located close to the city of Tocopilla, at the southern end of a known seismic gap in North Chile. Through modelling of Global Positioning System (GPS) and radar interferometry (InSAR) data, we show

Evidence for Anthropogenic Surface Loading as Trigger Mechanism of the 2008 Wenchuan Earthquake

open access: yes, 2011
Two and a half years prior to China's M7.9 Wenchuan earthquake of May 2008, at least 300 million metric tons of water accumulated with additional seasonal water level changes in the Minjiang River Valley at the eastern margin of the Longmen Shan.

Buried shallow fault slip from the South Napa earthquake revealed by near-field geodesy. [PDF]

open access: yes, 2017
Earthquake-related fault slip in the upper hundreds of meters of Earths surface has remained largely unstudied because of challenges measuring deformation in the near field of a fault rupture.

Coseismic and postseismic slip ruptures for 2015 Mw 6.4 Pishan earthquake constrained by static GPS solutions

open access: yesGeodesy and Geodynamics, 2016
On 3 July 2015, a Mw 6.4 earthquake occurred on a blind fault struck Pishan, Xinjiang, China. By combining Crustal Movement Observation Network of China (CMONOC) and other Static Global Positioning System (GPS) sites surrounding Pishan region, it ...

The Sanriku-Oki low-seismicity region on the northern margin of the great 2011 Tohoku-Oki earthquake rupture [PDF]

open access: yes, 2012
We examine a region of the megathrust fault offshore of northeastern Honshu (38.75°–40.25°N, 141.5°–143.25°E) that we designate as the Sanriku-Oki low-seismicity region (SLSR). The SLSR, located near the northern termination of the 2011 Tohoku-Oki (M_w 9.
