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

Identification, prediction and mitigation of sinkhole hazards in evaporite karst areas [PDF]

, 2008
Sinkholes usually have a higher probability of occurrence and a greater genetic diversity in evaporite terrains than in carbonate karst areas. This is because evaporites have a higher solubility, and commonly a lower mechanical strength.

A New Approach to Imaging Deep Crustal Structures: Implications for the Crustal Architecture of Southeast Australia's Passive Margin

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 4, April 2025.
Abstract In the passive margin of southeast Australia, a mosaic of tectonic structures of the Otway Basin records the protracted Cretaceous to Eocene break‐up evolution of Australia and Antarctica. Here, we use an innovative approach that combines Euler deconvolution and DBSCAN clustering of global magnetic data and drill‐hole‐constrained ...

Fault specific GIS based seismic hazard maps for the Attica Region, Greece [PDF]

, 2018
Traditional seismic hazard assessment methods are based on the historical seismic records for the calculation of an annual probability of exceedance for a particular ground motion level. A new fault specific seismic hazard assessment method is presented,

Comparison of Paleoearthquake Elapsed‐Times and Mean Interevent‐Times for a Global Data Set of Active Faults: Implications for Future Earthquakes and Seismic Hazard

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 4, April 2025.
Abstract The timing and size of successive prehistoric earthquakes on individual active faults are key for understanding seismic processes and time‐dependent seismic hazards. Here, we analyze interevent and elapsed times for 890 large prehistoric and historic earthquakes on 210 normal, reverse and strike‐slip faults from five active tectonic regions ...

Compilation of parameterized seismogenic sources in Iberia for the SHARE European-scale seismic source model. [PDF]

, 2010
: SHARE (Seismic Hazard Harmonization in Europe) is an EC-funded project (FP7) that aims to evaluate European seismic hazards using an integrated, standardized approach.

Australian paleoseismology: towards a better basis for seismic hazard estimation

Annals of Geophysics, 2003
Probabilistic seismic hazard analyses in Australia rely fundamentally on the assumption that earthquakes recorded in the past are indicative of where earthquakes will occur in the future.

On a flawed conclusion that the 1255 A.D. earthquake ruptured 800 km of the Himalayan Frontal Thrust east of Kathmandu

Geophysical Research Letters, 2016
A reexamination of the observations and analysis recently reported to conclude that an 800 km section of the Himalayan Frontal Thrust ruptured in 1255 A.D. shows that the conclusion is flawed and without merit because of misinterpretations of trench logs

Application of Tree-Ring Analysis to Paleoseismology [PDF]

Reviews of Geophysics, 1997
Knowledge of a region's seismicity is one of the keys to estimating earthquake hazards. Unfortunately, historical records are generally inadequate for evaluations of seismicity. Paleoseismology addresses this problem using various techniques for dating earthquake‐disturbed materials.
