... literature for >30 years, although some 3D seismic data-based studies support the constant-length model. Because they make different predictions regarding rift development, and earthquake size and recurrence intervals in areas of continental extension, it is critical to test these models with data from...

.... Here, we constrain rupture directivity of four major induced earthquakes ( M w ≥ 5.0 ) in the central United States that occurred between 2011 and 2016. We utilize the rich pool of broadband and strong‐motion seismic data and select smaller earthquake recordings as empirical Green’s functions (EGFs...

In early 2017, it was decided that to streamline ShakeAlert processing, the remaining algorithms should be merged as the system’s single point‐source algorithm. Because ElarmS historically created more alerts for earthquakes and more accurate...

...Tianxiang Li; T. Y. Yang, M. EERI; Genshu Tong; Dorian P. Tung; Yuanjie Li A fused steel diagrid frame (FSDF) is an innovative earthquake resilient structural system. FSDF combines the steel diagrid structural system with shear links (SLs) and moment connections (MCs) to dissipate earthquake energy...

The geometric mean of the two horizontal components of acceleration or velocity, as used in many ground-motion prediction equations, is typically 0.76 times the magnitude of this vector peak. Accelerations in the top 100 come from earthquakes as small...
