Seismic monitoring systems provide valuable data and information on the behavior of buildings leading to improved understanding and better design codes. For these reasons, many municipalities (require seismic instrumentation or offer benefits such as reduced inspection time as part of a building occupancy resumption program.

The main purpose of this policy is to gather information about building response to earthquake, to enable rapid evaluation of potential damage. By monitoring the ground movement only, nothing will be learnt about the building response during a seismic event. If a single accelerograph is to be installed in a building, highly recommend that this instrument be located at the top of the building. Monitoring the ground will only provide us with input motion information, which will be very similar over large areas with similar soil profiles, so top-of-building motion relative to ground motion recorded at a nearby location would give a better measure of structural response.

Ground motion is useful as the input to engineering models that theoretically predict the response of the building, but recording building motion would provide actual structural response data, and it would be of most use when used in conjunction with synchronised ground motion recording.
