Emergency Operations Centers are one of four NIMS Command and Coordination structures.
ICS is used to manage on-scene, tactical-level response; EOCs are off site locations where staff from multiple agencies come together to:
Address imminent threats and hazards
Provide coordinated support to incident command, on-scene personnel and/or other EOCs
The purpose, authorities, and composition of EOCs vary widely, but EOCs generally perform the following primary functions:
Collecting, analyzing and sharing information
Supporting resource needs and requests, including allocation and tracking
Coordinating plans and determining current and future needs
In some cases providing coordination and policy direction
Some agencies and departments utilize operations centers. EOCs are multidisciplinary and in this aspect are different from operations centers employed by a single organization.
EOCs can be fixed locations, temporary facilities or virtual structures with staff participating remotely.
