Emergency Operations Centers frequently have multiple activation levels to allow for:
Response scaled to the incident
Delivery of the exact resources needed
A level of coordination appropriate to the incident
The level of activity within a center often increases as the size, scope, and complexity of the incident grow.
If the incident requires additional support and coordination, the EOC director may activate additional staff to involve more disciplines, mobilize additional resources, inform the public, address media inquiries, involve senior elected and appointed officials, and request outside assistance.
