This seminar presents IFAS, a novel low-damage seismic system developed through a multi-university NSF NHERI project led by the University of Arizona. Validated via large-scale shake table and lab tests at UCSD and Lehigh, IFAS uses deformable connections and self-centering walls to reduce seismic and wind demands.

Earthquake recordings are of great benefit to support site-specific seismic hazard assessments for critical infrastructure but can also bring broader benefits when the seismometer installations are integrated into the wider national seismic monitoring network.  This presentation describes the planning, deployment and operation of a string of seismic sensors in a single borehole at the proposed Bradwell B nuclear power station site in November 2018 and how the data captured has been used to enhance earthquake detection as part of the BGS national seismic network and for site characterisation for a probabilistic seismic hazard analysis (PSHA) undertaken by Jacobs.
