The Seismic Expression of Core Complex‐Style Extensional Detachment Faults in Rifted Margins

open access: yesTerra Nova, EarlyView.
ABSTRACT The identification of core complex‐style extensional detachment faults (CCDFs) in rifted margins is crucial for accurately restoring their stratigraphic and thermal histories. Yet recognising CCDFs in seismic reflection images is challenging due to their faint topographic expression; the lack of associated abrupt offset in seismic reflections;

Building a Continental‐Scale Geodetic Network: The Plate Boundary Observatory (PBO)

open access: yesPerspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract The Plate Boundary Observatory (PBO) transformed the use of geodesy in North America to study crustal deformation and plate boundary processes by establishing a continental‐scale, standardized, open‐access geodetic network. Built and operated by UNAVCO between 2003 and 2018 as part of the National Science Foundation (NSF)‐funded EarthScope ...

Seismic Performance Spectra

Advanced Materials Research, 2010
The seismic performance spectrum is a new kind of the response spectra which is formed according to the designated performance objectives. The performance objectives are changed according to the performance objective level and period of structure, and are different in the acceleration sensitive, velocity sensitive and displacement sensitive range in ...

Enhancing Performance-Based Bridge Seismic Design with Seismic Performance Testing

Transportation Research Record: Journal of the Transportation Research Board, 2005
Introducing performance-based criteria to bridge seismic design increases the demand for seismic performance testing results that can be compared with each other to provide critical information used in the design. The current practice of seismic performance testing of bridge piers employs diverse testing conditions.

Seismic demand on non‐structural elements for quantifying seismic performance factors

Earthquake Engineering & Structural Dynamics, 2022
AbstractThe quantification of non‐structural seismic performance factors is a crucial step to improve the seismic performance of non‐structural elements (NSEs). Non‐structural seismic performance factors currently included in modern seismic design provisions are mainly based on engineering judgment and have not been calibrated to meet specific ...
