National/International Systems Last-Mile Hazard Warning System

Detection and Modeling

Early Warning Message Relay ICT Networks Community

D&M and EW Systems can work as a closed system but purpose of saving lives is defeated if not connected to the LM-HWS

LM-HWS gets it’s input from the Early Warning Systems, a necessary condition

Without the input from EWS, the LM-HWS cannot provide feedback to the EWS for it to measure its performance and correct the shortcomings; in return D&M System will not get proper feedback for system enhancements

Communities have a self-feedback to ensure ERPs are reliable and effective; Communities can work as standalone closed systems but would require ERPs that can be executed in Zero time; i.e. be able to function without Institutional EWs and depend on tacit knowledge and natural observations

Communities provide feedback to Message Relays to notify receipt of notification; as a result performance of the Message Relay and ICT Networks are measured through the Community feedback

Staff at the HIH monitor hazard events around-the-clock

When an “Event of Interest” is detected, HIH follows a protocol that may result in the issuance of a message to ICT Guardians over multiple modes

ICT-Gs receive messages and acknowledge receipt

If urgent or high-priority alerts, ICT-Gs notify local ERP-Coordinators in the community using locally agreed on methods

In real cases, ICT-Gs and ERP-Cs will await official warnings

In live tests, ERP-Cs activated local ERP and were timed
