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

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.

Fires following the 2024 Noto Peninsula earthquake: Insights from ignition records, a fire damage survey, and a prospective regional fire risk assessment

Earthquake Spectra, Volume 41, Issue 3, Page 1998-2027, August 2025.
Rupture of an active fault across the Noto Peninsula, Japan, generated a moment magnitude 7.5 earthquake on 1 January 2024 causing multiple cascading hazards with significant impacts on communities. This study focuses on the fire‐following‐earthquake aspects of the 2024 Noto Peninsula earthquake.

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 ...

Seismotectonics and Crustal Structure in the Southern Dominican Republic Offshore Margin: Implications on the Tsunami Potential

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 6, June 2025.
Abstract Many coastal areas of the southern Dominican Republic experience considerable population pressure accompanied by important economic activity. The southern offshore margin is characterized by significant seismicity and active geological processes.

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

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.

Slow Rupture, Long Rise Times, and Multi‐Fault Geometry: The 2020 M6.4 Southwestern Puerto Rico Mainshock

Geophysical Research Letters, Volume 52, Issue 8, 28 April 2025.
Abstract The M6.4 mainshock of the southwestern Puerto Rico seismic sequence on 7 January 2020, was one of the most impactful modern earthquakes in the northeastern Caribbean. Due to its offshore location and complex aftershock distribution, its source kinematics remain poorly constrained.

Softening and Recovery of Near‐Surface Layers During the 2024 M7.6 Noto Earthquake

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 4, April 2025.
Abstract On 1 January 2024, a devastating MJ 7.6 earthquake occurred on the Noto Peninsula in Japan. When such a strong earthquake occurs, affected near‐surface soil layers behave nonlinearly and may undergo some structural changes driven by Flow Liquefaction, Cyclic Mobility, or Slow Dynamics phenomena.
