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.
