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

Seismic vulnerability and fragility of steel buildings
, 2008 The main goal of this article is to evaluate the structural behavior of steel buildings. The seismic performance ofa specific steel building located in the campus of the National University of Colombia in Manizales is assessed.The seismic demand is characterized by a peak effective acceleration of 0.25 g.

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