What does the facility seismic zone rating mean?
Seismic zone ratings are classified geographically by risk level from Zone 4 (IV) being the highest risk to Zone 0 indicating no risk from seismic activity. Facilities considered essential, such as government, police, medical, or fire facilities, must be rated seismically. Some data center facilities are seismically rated for customer assurance that risks are minimized based on the seismic zone rating for the geographic location. Building infrastructure, generators, floor composition, equipment racks, etc must be adequately rated to be in full compliance with the geographic zone rating.
