Damage‐informed ground motion and semi‐empirical fragility assessment

Earthquake Engineering &Structural Dynamics, Volume 53, Issue 11, Page 3514-3526, September 2024.
Abstract Calibrating parametric fragility curves via empirical damage data is one of the standard approaches to derive seismic structural vulnerability models. Fragilities based on empirical data require the characterization of the ground motion (GM) intensity at the building sites in the area affected by the earthquake producing the observed damages ...

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.

Surface Rupture of the 2008 Mw 6.6 Nura Earthquake: Triggered Flexural‐Slip Faulting in the Pamir‐Tien Shan Collision Zone

Tectonics, Volume 43, Issue 9, September 2024.
Abstract This study investigates the intricate relationship between earthquake sources and seismogenic surface ruptures in a complex tectonic setting with active faults in the continental collision zone between the southern Tien Shan and the northern Pamir Mountains in Central Asia.

Earthquake scenario development in conjunction with the 2023 USGS National Seismic Hazard Model

Earthquake Spectra, Volume 40, Issue 3, Page 1818-1844, August 2024.
We present earthquake scenarios developed to accompany the release of the 2023 update to the US Geological Survey National Seismic Hazard Model (NSHM). Scenarios can serve a range of local and regional needs, from developing proactive‐targeted mitigation strategies for minimizing impending risk to aiding emergency management planning.

Incorporating Intensity Distance Attenuation Into PLUM Ground‐Motion‐Based Earthquake Early Warning in the United States: The APPLES Configuration

Earth's Future, Volume 12, Issue 2, February 2024.
Abstract We develop Attenuated ProPagation of Local Earthquake Shaking (APPLES), a new configuration for the United States West Coast version of the Propagation of Local Undamped Motion (PLUM) earthquake early warning (EEW) algorithm that incorporates attenuation into its ground‐motion prediction procedures.

Sediment thickness map of United States Atlantic and Gulf Coastal Plain Strata, and their influence on earthquake ground motions

Earthquake Spectra, Volume 40, Issue 1, Page 89-112, February 2024.
With the recent successful accounting of basin depth ground‐motion adjustments in seismic hazard analyses for select areas of the western United States, we move toward implementing similar adjustments in the Atlantic and Gulf Coastal Plains by constructing a sediment thickness model and evaluating multiple relevant site amplification models for central

CyberShake-derived ground-motion prediction models for the Los Angeles region with application to earthquake early warning [PDF]

, 2017
Real-time applications such as earthquake early warning (EEW) typically use empirical ground-motion prediction equations (GMPEs) along with event magnitude and source-to-site distances to estimate expected shaking levels.

Bayesian analysis of ground motion models using chimney fragility curves: 2021, 5.9‐Mw Woods Point intraplate earthquake, Victoria, Australia

Earthquake Spectra, Volume 40, Issue 1, Page 732-759, February 2024.
The 22 September 2021 (AEST) MW 5.9 Woods Point earthquake occurred in an intraplate setting (southeast Australia) approximately 130 km East Northeast of the central business district of Melbourne (pop. ∼5.15 million). A lack of seismic instrumentation and a low population density in the epicentral region resulted in a dearth of near‐source ...
