The Emergency Operations Center

The Emergency Operations Center (EOC) serves a critical role in every phase of disaster response. 

It is the information and resource coordination hub, where the Incident Management Team (IMT) can analyze data, plan for impacts, and prepare to help responders conducting Emergency Support Functions (ESFs) to stabilize Community Lifelines.  While on-scene response operations are managed from an Incident Command Post (ICP) in the field, the IMT in the EOC coordinates plans for future operations, gathers the information needed to keep everyone well informed, and obtains the resources needed to support operations in the field.

The EOC is always activated.    

​

The day-to-day operational status for the EM staff is often called “Blue Skies” operations; monitoring for unexpected hazards, training, testing equipment, conducting drills and exercises, teaching classes, and sharing information to make sure everyone is ready for a disaster.  

​

Enhanced operations occur when there is a looming threat, hazardous weather conditions, or a local disaster such as a train wreck occurs – basically anytime EM specialists are monitoring a specific hazard or condition, preparing for potential impacts from a hazard, or planning, coordinating, and providing support for responders on a local incident such as a wildfire.  A wide range of operations take place at this level.  EM specialists frequently find themselves activated to "Level 2."  Most local incidents can be effectively managed, supported, and resolved at this level.    

  • EM personnel perform core EOC IMT functions such as Situational Analysis, Planning, Resource Management, Logistics, and Public Information. 

  • EOC IMT members collect and analyze situational data and plan for contingencies.  The team documents local needs and decisions, the actions partners are taking on their own, and helps coordinate or obtain scarce resources needed by partners so they can continue to operate.

  • The EOC IMT Public Information Officer (PIO) serves as the one official source for incident information shared with the public.  

​​

When a potentially catastrophic emergency is expected or Community Lifelines are or may be significantly disrupted, and the resources needed to stabilize them far exceed local capabilities:  

  • Local government officials can declare a Local State of Emergency (LSE).  The LSE lifts certain purchasing restrictions so that emergency resources can be obtained quickly.  A delegation of authority to the EOC AHIMT typically allows the team to utilize all resources necessary (local government staff, public facilities, equipment, and supplies) to implement protective measures on the jurisdiction's behalf. 

  • Some government offices might be closed and/or some public services may be suspended while departmental resources are helping with the local disaster response.

  • The EOC AHIMT may obtain additional resources through the Statewide Mutual Aid Agreement to run critical emergency response operations that are not, or cannot be, managed by local departments/agencies:  mass care shelters, large scale search and rescue efforts, formal damage assessments, and points of distribution for water and food supplies.

  • Points of Contact for recognized Emergency Support Functions (ESFs) support the EOC AHIMT response by maintaining situational awareness and coordinating or helping to locate resources for unmet needs.  

  • The EOC AHIMT and ESF POCs can continue to analyze the changing situation, plan for "next steps," and support the response operations until the emergency de-escalates and the community is ready to begin its disaster recovery process.  

Emergency management professionals typically break down their responsibilities into four phases, which form a cycle of activities that take place before, during, and after a disaster. 

This cycle applies to residents and businesses, too.

  • Before a disaster strikes, PREPAREDNESS activities (planning, equipping, training, and exercising) get the community and responders ready for all types of hazards.

  • During and immediately following a disaster, RESPONSE actions protect lives and property and stabilize community lifelines.

  • RECOVERY efforts focus on rebuilding after a disaster; that can take days to years, depending on the extent of the damage to the community.  Really big disasters can create unemployment and heighten demand for social services, all while reducing tax revenue for local government.  Successful recoveries depend on well-prepared residents, resilient businesses, and properly insured properties.

  • MITIGATION projects reduce risks and losses from future hazards – they may take place after a disaster during long-term recovery or while preparing for a hazard, but they are always intended to improve conditions and strengthen resilience before the next event.

Lifelines

Each Community Lifeline includes sub-component lifelines. 

During a disaster response, the status of each component is assessed and the EOC IMT identifies ways to quickly bridge any gaps in Community Lifelines by facilitating Emergency Support Functions by coordinating partners and resources.  Specific operations may be conducted by the EOC IMT, like providing safe shelter for displaced people and their pets, supporting the public health and medical systems, ensuring clean drinking water is available, or organizing post-disaster recovery centers after a disaster.  

After the emergency response, local government, private industry, and charitable organizations take over Recovery Support Functions:  removing disaster debris, rebuilding damaged infrastructure, finding transitional housing options for residents in need, and supporting the return of social and economic stability.
