The Early Evolution of a Young Normal Fault in the Aysén Fjord, Chile

Tectonics, Volume 44, Issue 7, July 2025.
Abstract Seismic reflection data have been used to investigate the evolution of faults in oil and gas basins for decades and typically image deeply buried faults at low resolution, with biostratigraphic age control to date horizons at scales of 10 Myr.

Diachronous Accumulation of Mid‐Pleistocene Gravel Beds Driven by Tectonics Across the Tibetan Plateau

Geophysical Research Letters, Volume 52, Issue 7, 16 April 2025.
Abstract Deciphering how the widespread late Cenozoic conglomerates were formed across the Tibetan Plateau is crucial for understanding the competition between tectonics and climate. Here we target the mid‐Pleistocene conglomerate cap along the northern Saishiteng range (SR), North Tibet. 26Al/10Be burial dating constrains the onset accumulation of the

Paleoseismic and Slip-Rate Observations along the Honey Lake Fault Zone, Northeastern California, USA [PDF]

, 2008
The Honey Lake fault is a major strike-slip fault in northeastern California that accommodates northwest-directed right-lateral shear in the northern Walker Lane.

Late Quaternary activity of the NW Cardrona Fault, Otago, New Zealand

New Zealand Journal of Geology and Geophysics, Volume 68, Issue 1, Page 151-171, March 2025.
ABSTRACT We use new paleoseismic data and lidar to reassess late Quaternary activity of the NW (northwest) Cardrona Fault, a ∼60 km long range‐bounding fault in Otago. Paleoseismic investigations of the NW Cardrona Fault were conducted in the 1980s, but findings were limited by a paucity of materials suitable for dating.

Ultra-thin clay layers facilitate seismic slip in carbonate faults [PDF]

, 2017
Many earthquakes propagate up to the Earth's surface producing surface ruptures. Seismic slip propagation is facilitated by along-fault low dynamic frictional resistance, which is controlled by a number of physico-chemical lubrication mechanisms.

Paleo‐Earthquake Fingerprints and Along‐Strike Slip Variation of the Silent Mt. Morrone Normal Fault (Central Italy): A Structural‐Geochemical Approach

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 2, February 2025.
Abstract This study provides insights into the tectonic evolution of the normal Mt Morrone Fault System (MMFS) in Central Italy and highlights the utility of multidisciplinary approaches in reconstructing the seismic history of dormant fault systems. The MMFS comprises two parallel normal faults that traverse the western slope of Mt.

An integrated Structure-from-Motion and time-lapse technique for quantifying ice-margin dynamics [PDF]

, 2017
Fine resolution topographic data derived from methods such as Structure from Motion (SfM) and Multi-View Stereo (MVS) have the potential to provide detailed observations of geomorphological change, but have thus far been limited by the logistical ...

Shallow Lake, Strong Shake: Record of Seismically Triggered Lacustrine Sedimentation From the 1959 M7.3 Hebgen Lake Earthquake Within Henrys Lake, Idaho

Geophysical Research Letters, Volume 51, Issue 22, 28 November 2024.
Abstract We investigate a shallow lake basin for evidence of a large historic intraplate earthquake in western North America. Henrys Lake, Idaho is an atypical candidate for lacustrine paleoseismic study given its shallow depth (∼7 m) and low relief (≤2° slopes).

The Mesozoic palaeorelief of the northern Tian Shan (China) [PDF]

, 2011
International audienceThe Tian Shan range offers a natural laboratory to study orogenic processes. Most of the previous studies focused on either the Palaeozoic evolution of the range or its Cenozoic intracontinental evolution linked with the India-Asia ...

The 2023 Alaska National Seismic Hazard Model

Earthquake Spectra, Volume 40, Issue 4, Page 2545-2597, November 2024.
US Geological Survey (USGS) National Seismic Hazard Models (NSHMs) are used extensively for seismic design regulations in the United States and earthquake scenario development, as well as risk assessment and mitigation for both buildings and infrastructure.
