The Robert A. Millikan Library is a reinforced concrete building located on the campus of the California Institute for Technology in Pasadena, USA. The building has been studied by earthquake engineers since it was first instrumented in the late 1960s. Continuous measurements at 200 Hz are made by 19-bit real-time seismometers on each of the 10 floors and in the basement. These seismometers measure the response of the library in the north-south direction and in the east-west direction.
