Inelastic Dilatancy as a Mechanism for Coseismic Fluid Depressurization of a Shallow Fault Zone

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract Hydrologic observations and experimental studies indicate that inelastic dilation from coseismic fault damage can cause substantial pore pressure reduction, yet most near‐fault hydromechanical models ignore such inelastic effects. Here, we present a 3‐D groundwater flow model incorporating the effects of inelastic dilation based on an ...

Ground effects induced by the 2012 seismic sequence in Emilia: implications for seismic hazard assessment in the Po Plain

Annals of Geophysics, 2012
Since May 16, 2012, a seismic sequence has affected a wide portion of the Emilia Region (northern Italy), chiefly for the Modena and Ferrara Provinces. The first mainshock (Ml 5.9; focal depth, ca.

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 ...

Dual-Polarimetric SAR Measurements to Observe Liquefaction Surface Manifestations

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
In this study, a methodology is proposed to use dual-polarimetric synthetic aperture radar (SAR) to identify the spatial distribution of soil liquefaction. The latter is a phenomenon that occurs in conjunction with seismic events of a magnitude generally

Landslides Triggered by the 2016 Mw 7.8 Pedernales, Ecuador Earthquake: Correlations with ESI-07 Intensity, Lithology, Slope and PGA-h

Geosciences, 2019
We provide a dataset of the landslides induced by the 2016 Pedernales megathrust earthquake, Ecuador (Mw 7.8, focal depth of 20 km) and compare their spatial distribution with mapped bedrock lithology, horizontal peak ground acceleration (PGA-h) and the ...

Insights into temporal earthquake clustering from the Settlement Fault, southeastern Otago, Aotearoa New Zealand

New Zealand Journal of Geology and Geophysics, Volume 68, Issue 4, Page 747-772, December 2025.
ABSTRACT We combine previous studies, fieldwork, lidar data, and trenching to examine late Quaternary activity of the SE‐dipping ≥23 km long Settlement Fault in the southeastern South Island. Trenching of a scarp crossing a small alluvial fan exposed a > 3 m thick sequence of folded sandy to silty fan alluvium.

Use of the ESI-2007 scale to evaluate the 2003 Boumerdès earthquake (North Algeria)

Annals of Geophysics, 2016
In this study, we applied the environmental seismic intensity (ESI-2007) scale to a major recent Algerian earthquake. The ESI-2007 scale is an effective tool to assess the seismic hazard and has been applied to onshore earthquakes.

Twenty‐Five Years of Probabilistic Fault Displacement Hazard Assessment

Reviews of Geophysics, Volume 63, Issue 3, September 2025.
Abstract Fault displacement hazard poses significant risks to critical infrastructure such as buildings, roads, and pipelines. While some structures can tolerate a certain degree of surface displacement, others, such as buildings, are far more vulnerable. Probabilistic Fault Displacement Hazard Assessment (PFDHA) quantifies the probability of exceeding
