Strong Shaking From Past Cascadia Subduction Zone Earthquakes Encoded in Coastal Landforms

Geophysical Research Letters, Volume 52, Issue 2, 28 January 2025.
Abstract Strong earthquakes along subduction zones are often devastating events, but sparse records along some tectonic margins limit our understanding of seismic hazards. Constraining shaking intensities is critical, especially in subduction zones with infrequent but large‐magnitude earthquakes like the Cascadia Subduction Zone (CSZ), where the lack ...

Quaternary faulting in the central Paris basin: Evidence for coseismic rupture and liquefaction

, 2013
We describe new evidence of Quaternary faulting observable in large outcrop exposures (trenches and carries) near Romilly-sur-Seine in the centre of Paris basin. Coeval normal or reverse faults affect sand, marl and gravel units that also expose liquefaction features.

Modeling the Onset of Earthquake‐Triggered Landslides on Slip Surfaces Governed by Rate‐And‐State Friction

Geophysical Research Letters, Volume 51, Issue 24, 28 December 2024.
Abstract Earthquake‐triggered landslides are a severe hazard and contribute to landscape evolution. To understand their process and controlling factors, we model the onset of seismically‐triggered slip on pre‐existing slip surfaces governed by laboratory‐based rate‐and‐state friction, including wave propagation effects.

Surface-Rupturing Historical Earthquakes in Australia and Their Environmental Effects: New Insights from Re-Analyses of Observational Data

Geosciences, 2019
We digitize surface rupture maps and compile observational data from 67 publications on ten of eleven historical, surface-rupturing earthquakes in Australia in order to analyze the prevailing characteristics of surface ruptures and other environmental ...

The Multi‐Segment Complexity of the 2024 MW ${M}_{W}$ 7.5 Noto Peninsula Earthquake Governs Tsunami Generation

Geophysical Research Letters, Volume 51, Issue 21, 16 November 2024.
Abstract The 1 January 2024, moment magnitude MW $\left({M}_{W}\right)$ 7.5 Noto Peninsula earthquake ruptured in complex ways, challenging analysis of its tsunami generation. We present tsunami models informed by a 6‐subevent centroid moment tensor (CMT) model obtained through Bayesian inversion of teleseismic and strong motion data.

Slip History, Tectonic Evolution, and Fault Zone Structure Along the Southern Alpine Fault, New Zealand

Geochemistry, Geophysics, Geosystems, Volume 25, Issue 11, November 2024.
Abstract The study of active fault zones is fundamental to understanding both long‐term tectonics and short‐term earthquake behavior. Here, we integrate lidar‐enabled geomorphic‐geologic mapping and petrochronological analysis to reveal the slip‐history, tectonic evolution, and structure of the southern Alpine Fault in New Zealand.

Clues to the identification of a seismogenic source from environmental effects: the case of the 1905 Calabria (Southern Italy) earthquake [PDF]

Natural Hazards and Earth System Sciences, 2009
The 8 September 1905 Calabria (Southern Italy) earthquake belongs to a peculiar family of highly destructive (I₀=XI) seismic events, occurred at the dawning of the instrumental seismology, for which the location, geometry and size ...
