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.

La Zona de Falla del Bajo Segura: cabalgamiento activo “ciego” en la Cordillera Bética oriental [PDF]

, 2012
The Bajo Segura Fault Zone, located at the NE end of the Eastern Betic Shear Zone, has been the site of some of the most intense seismic activity on the Iberian Peninsula in the historical and instrumental time periods.

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.

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 ...

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 ...

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.

Long-period surface motion of the multi-patch Mw9.0 Tohoku-Oki earthquake [PDF]

, 2014
We show that it is possible to capture the oscillatory ground motion induced by the Tohoku-Oki event for periods ranging from 3 to 100s using Precise Point Positioning (PPP).
