In collaboration with the U.S. Department of Veterans Affairs (VA), the National Strong Motion Project of the U.S. Geological Survey has been installing sophisticated seismic systems that will monitor the structural integrity of VA hospital buildings located in conterminous United States, Alaska and Puerto Rico during earthquake shaking. These monitoring systems, which combine sensitive accelerometers and real-time computer calculations, are capable of determining the structural health of each instrumented structure rapidly after an event, helping to ensure the safety of patients and staff. These efforts in turn will help the U.S. Department of Veterans Affairs safeguard its building inventory from future earthquake losses.

Select a circle on the map to see details at each instrumented structure. Note that some structures have both building arrays and reference sites where “green” and “blue” markers may overlap (you can toggle the layers using the controller in the top right corner of the map).
