The Atwood building is instrumented from the basement to the roof with a total of 32 accelerometer sensors. The building is located just two blocks north of the Delaney Park downhole array. Together the form a richly instrumented system that records local ground motions and building response.

The complete instrumentation details are illustrated by this diagram (courtesy of the USGS).
