Small-strain site response of soft soils in the Sacramento-San Joaquin Delta region of California conditioned on VS30 and mHVSR

Earthquake spectra
Sites located in the Sacramento-San Joaquin Delta region of California typically have peaty-organic soils near the ground surface, which are characteristically soft, with shear wave velocities as low as 30 m/s.

A Global Application Programming Interface–Enabled Earthquake Ground Motion Relational Database for Engineering Applications

Earthquake Spectra, Volume 41, Issue 5, Page 4162-4194, December 2025.
We present a application programming interface (API)‐enabled relational database of global earthquake ground motion intensity measures, associated metadata, and processed time‐series data. Raw ground motion records were processed by the authors using either manual or semi‐automated processing procedures, and every processed record has passed a quality ...

Does VS30 reflect seismic amplification? Observations from the West Bohemia Seismic Network

Natural Hazards
The present study addresses verification of average seismic shear-wave velocity from the surface to a depth of 30 m (VS30) as a suitable proxy for a seismic amplification.

Evaluating liquefaction exposure of road networks to support decision‐making

Earthquake Spectra, Volume 41, Issue 5, Page 3337-3364, December 2025.
This article discusses different approaches to evaluate liquefaction exposure across road networks and inform decision‐making processes regarding asset management, emergency preparation and response planning. Using the New Zealand State Highway network, liquefaction exposure is assessed based on ground shaking from two sources: (1) various return ...

Functional recovery time of low‐rise concentrically braced frame buildings: Probabilistic assessment of footing size effects

Earthquake Spectra, Volume 41, Issue 5, Page 3669-3694, December 2025.
A city’s capacity to withstand and recover from seismic events plays a crucial role in safeguarding the well‐being of its residents. While numerous studies have investigated the recovery cost and time of buildings following earthquakes, the effects of soil and foundation have often been overlooked despite their known influence on seismic performance ...

Estimating site amplification variability in Yangon, Myanmar, from a dense nodal seismic array

Earthquake Spectra, Volume 41, Issue 4, Page 3168-3189, November 2025.
We explore a novel acquisition geometry that can be used to estimate the linear component of site amplification using a dense nodal seismic network installed in Yangon, Myanmar’s largest city. The city is surrounded by several seismically active faults, including the Sagaing Fault, which is capable of generating Mw > 7.0 earthquakes.
