Which statement correctly matches the first two steps with their channels?

• A. Initial Report via Horizontal Communications; Information Dissemination via Vertical Communications
• B. Initial Report via National Command Center; Information Dissemination via Horizontal Communications
• C. Initial Report via Vertical Communications; Information Dissemination via National Command Center
• D. Initial Report via Vertical Communications; Information Dissemination via Horizontal Communications

Answer: (D)

Information flows during an incident follow a clear pattern: report up the chain to the person in command (vertical communication) to ensure leadership has the alert and can initiate the response, then share information across peers at the same level (horizontal communication) so all teams stay coordinated and informed. The initial report needs to move upward to establish command and accountability, while dissemination spreads laterally to synchronize actions among units that operate at the same level. Therefore, pairing Initial Report with vertical communications and Information Dissemination with horizontal communications correctly reflects how these two steps are typically handled.
