Real-time Finite Fault Rupture Detector (FinDer) for large earthquakes [PDF]

, 2012
To provide rapid estimates of fault rupture extent during large earthquakes, we have developed the Finite Fault Rupture Detector algorithm, ‘FinDer’. FinDer uses image recognition techniques to detect automatically surface-projected fault ruptures in ...

Observational Seismic Fragility Models for Unreinforced Masonry Buildings Based on Building‐by‐Building Damage Data From the 2012 Emilia Earthquakes

Earthquake Engineering &Structural Dynamics, Volume 54, Issue 11, Page 2927-2946, September 2025.
ABSTRACT Over recent decades, Italy has been affected by multiple earthquakes, revealing the significant vulnerability of existing structures. These seismic events have resulted in notable human and economic losses, emphasising the importance of evaluating the impact of one or more seismic events on various building types.

Uncertainty in Ground-Motion-to-Intensity Conversions Significantly Affects Earthquake Early Warning Alert Regions

The Seismic Record
We examine how the choice of ground-motion-to-intensity conversion equations (GMICEs) in earthquake early warning (EEW) systems affects resulting alert regions. We find that existing GMICEs can underestimate observed shaking at short rupture distances or

Did They Feel It? Legacy Macroseismic Data Illuminates an Engimatic 20th Century Earthquake

Earth and Space Science, Volume 12, Issue 9, September 2025.
Abstract The challenges and the importance of preserving legacy instrumental records of earthquakes are now well‐recognized (e.g., Richards & Hellweg, 2020, https://doi.org/10.1785/0220200053). Seismologists may not be aware of parallel challenges and opportunities with legacy macroseismic data for earthquakes in the United States. For much of the 20th

An open‐access simulated earthquake ground‐motion database for an M7 Hayward Fault earthquake in the San Francisco Bay Region

Earthquake Spectra, Volume 41, Issue 3, Page 2560-2597, August 2025.
Comprehensive understanding of earthquake ground motions, particularly in the near‐fault region of large‐magnitude events, is limited by gaps in strong‐motion data. This challenge is prominent in areas with high seismic hazard but infrequent large earthquakes where data is sparse and difficult to interpret.

Evaluating desktop methods for assessing liquefaction-induced damage to infrastructure for the insurance sector [PDF]

, 2015
The current method used by insurance catastrophe models to account for liquefaction simply applies a factor to shaking-induced losses based on liquefaction susceptibility.

Evaluating Simplified Methods for Liquefaction Assessment for Loss Estimation [PDF]

, 2016
Currently, some catastrophe models used by the insurance industry account for liquefaction by applying a simple factor to shaking-induced losses. The factor is based only on local liquefaction susceptibility and this highlights the need for a more ...

Shallow Fault Zone Structure Affects Rupture Dynamics and Ground Motions of the 2019 Ridgecrest Sequence to Regional Distances

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 6, June 2025.
Abstract Seismic faults are surrounded by damaged rocks with reduced rigidity and enhanced attenuation. These damaged fault zone structures can amplify seismic waves and affect earthquake dynamics, yet they are typically omitted in physics‐based regional ground motion simulations.
