Schematic of Atwood array and boreholes
The Advanced National Seismic System (ANSS) structural monitoring system in the 20- story Atwood Building is one of the most sophisticated systems in the country. Sensors are deployed on the parking and street levels, the electrical and mechanical levels, the roof level, and the 2nd, 7th, 8th, 13th, 14th, and 19th floors.

Delaney Park Borehole Array
The Robert Atwood building sensors are complemented by the Delaney Park borehole array. This array of buried, three-component sensors in six boreholes ranging in depth from 15 to 200 feet (5–60 meters), with a seventh sensor at the surface.
