Under which phase of the disaster do the three proposed interventions fall? Explain why you chose that phase.

The three proposed interventions fall under the preparedness phase of the disaster. Preparedness is defined as activities and measures taken in advance to be ready for a potential disaster or emergency event. These three interventions are designed to help mitigate damage from an unknown, potential disaster by getting citizens and organizations adequately prepared for whatever could come their way.

The first intervention focuses on educating people about the resources available to them during a crisis. This part of preparedness requires individuals to have knowledge of what they can do when faced with any kind of emergency so that they are aware and capable enough to respond accordingly. The second intervention emphasizes testing response plans ahead of time, which ensures that both citizens and organizations have a clear idea on how to react in unpredictable scenarios while minimizing disruption caused by an emergency situation. Lastly, the third intervention suggests coordinated exercises between different entities such as local governments, agencies, private-sector companies etc., which helps maintain continuity in operations if something unexpected arises as well as helping all parties involved become better equipped for more extreme events.

Overall, these three interventions are focused on preparing citizens and corporations for any potential disasters before it even happens; thus making them proactive rather than reactive during a crisis situation. As a result, this makes them fall under the preparedness phase of the disaster management cycle where prevention is prioritized over reaction.
