The Structural Extreme Events Reconnaissance (StEER) Network is pleased to release our Preliminary Virtual Reconnaissance Report (PVRR) in response to the M 6.4 and M 7.1 Ridgecrest, CA Earthquakes that occurred July 4 and 5, 2019. This report overviews the hazard characteristics of the earthquakes, the regulatory context and emergency response, the impacts of these earthquakes on the built environment, and current conditions by collocating publicly-reported information and was prepared in collaboration with EERI’s Virtual Earthquake Reconnaissance Team (VERT). As the DOI for the report curated at DesignSafe is still pending, those interested can immediately access the report at: https://aub.ie/steer_eq_prj2444.
As structural damage due to seismic loading was minimal, StEER will not deploy a Field Assessment Structural Team (FAST) at this time but will continue to support local collaborators already conducting structural assessments on the ground. Should significant structural damage be revealed through ongoing local investigations or due to subsequent aftershocks, StEER may deploy a FAST.
