Lichenometry dating of coseismic changes to a New Zealand landslide complex

Annals of Geophysics, 2003
Lichenometry is a surface-exposure-dating procedure that complements traditional trench-and-date stratigraphic studies of earthquakes. Lichens on the surficial blocks of a slump in the Seaward Kaikoura Range, South Island, New Zealand provide ...

Empirical Scaling Relationships Between Fault Length and Throw‐Rates Modulated by Fault Interactions in Extensional Regimes

Tectonics, Volume 45, Issue 5, May 2026.
Abstract Throw rates of active faults are expected to scale with fault length because the geometric moment of a fault is directly related to its dimensions. However, empirical data sets commonly display substantial scatter, which limits the use of fault scaling relationships for seismic hazard assessment and for understanding the mechanics of ...

Holocene Normal Faulting in the Southern Rocky Mountain Trench; Orogenic Collapse Modulated by Glacial Unloading?

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract The Southern Rocky Mountain Trench (SRMT) is a conspicuous valley in the eastern Canadian Cordillera. It lies above a sharp change in lithospheric strength and thickness and is occupied by a normal fault thought to have last been active in the Eocene.

Seismic Activity in the Celje Basin (Slovenia) in Roman Times—Archaeoseismological Evidence from Celeia

Quaternary, 2023
Searching for unknown earthquakes in Slovenia in the first millennium, we performed archaeoseismological analysis of Roman settlements. The Mesto pod mestom museum in Celje exhibits a paved Roman road, which suffered severe deformation.

A New Surface Rupture of the 1556 Huaxian M ∼ 8.5 Earthquake Revealed by Rock Surface Luminescence Dating of a Bedrock Fault Scarp and Colluvial Wedges

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Bedrock fault scarps and their associated colluvial wedges provide key evidence for reconstructing paleoearthquakes. We apply rock surface luminescence dating to a bedrock scarp on the Huashan fault in central China, using OSL‐depth profiles (DPs) from multiple heights. Results reveal two coseismic displacements of 6.8 and >1.0 m.

Towards new research strategies: silent seismogenic areas or silent sources?

Annals of Geophysics, 2000
Some earthquakes, particularly the strongest ones, can re-occur within hundreds or thousands of years. Therefore, the areas whose "seismic history" seems to be totally lacking in information are indeed a problem.

Directions in paleoseismology

Eos, Transactions American Geophysical Union, 1988
Paleoseismology is a new, rapidly evolving Earth science discipline that deals with the study of prehistoric earthquakes. It is a hybrid discipline that relies o n techniques and skills from many different Earth science specialities. Paleoseismology has provided new insight into the long‐term history of earthquakes on individual faults, thereby ...

Geolipidomics: Non‐Targeted Analysis of Rapidly Heated Geologic Samples With Gas‐Chromatography‐Mass Spectrometry

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 1, February 2026.
Abstract Lipids are powerful tools for reconstructing paleoenvironments and geologic processes because of their ubiquity and preservation in the rock record. Traditionally, organic geochemistry studies are targeted analyses of known biomarker compounds with known responses to past environmental conditions or geologic processes.

Difference in Slip Patterns Between Two Prehistoric Giant Earthquakes Along the Southern Kuril Trench

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract This study reveals different slip patterns of tsunami sources between two prehistoric giant earthquakes along the southern Kuril Trench, based on an integration of geological data and numerical simulations. The most recent giant earthquake occurred in the 17th century and its predecessor was in the 13th–14th century.

Landscape Signature of Seismogenic Faults in the Off and Onshore Domains of the Noto Peninsula in Japan's Back‐Arc

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract The eastern margin of the Sea of Japan is a zone of great seismic and tsunami hazard due to multiple offshore and nearshore reverse faults as shown by the 2024 Mw ${M}_{\mathrm{w}}$ 7.5 Noto Peninsula Earthquake. Here we compare coseismic deformation of the 2024 Noto Peninsula Earthquake with 4,767 individual marine terraces attributed to 16 ...
