arrays of accelerometers installed in buildings and other structures provide strong-motion data for rapid post-event assessments and long-term performance studies. In the United States, the U.S. Geological Survey's National Strong-Motion Project (NSMP) operates structural arrays and distributes building and structural records via the Center for Engineering Strong Motion Data (CESMD).

Instrumentation and data-quality practices for building vibration measurements are guided by international standards. ISO 4866 provides principles for measuring
