Concept Development

Final concept

The final concept is based upon the pre-existing technology of emergency buttons on college campuses. These emergency buttons, placed all over the island of Puerto Rico, will provide communication between residents and call centers. These terminals will be coordinated by a central hub in San Juan, the capital. Terminals will be staffed by workers responsible for allocating resources post-disaster. Terminals will be built off the current 911 call centers in Puerto Rico. Emergency buttons will be placed outside of public buildings such as high schools, hospitals, and police stations. The terminals and central hub will be connected via an underground system of fiber optic cables. Each terminal has a power system independent of the current Puerto Rican power grid. Solar panels added to the emergency buttons serve as a redundant power source.

Risk Assessment
