Abstract:Web-based interactive dashboards are an emerging technology and are useful in many sectors, majorly for decision-making through understanding the situation or the scenario in a composed view. Dashboards are commonly used in business for information management and to view the performance of the organization. The use of Dashboards in the field of Disaster management is still in the growing phase. Disasters are common, and they affect the community directly by impacting the lives or through Critical infrastructure (CI) service failures. Multiple Infrastructures are considered critical based on the country. These are affected directly or indirectly due to the hazards that occur in that area. The indirect impact on the CI is often not visible, and the delay in responding to them may cause heavy damage to the community residing in that area. The damage of one CI leads to the damage of another CI, resulting in cascading effects. The CI are the country's backbone, and any disruptions to them will disturb the normal state of the community. Knowledge about CI service failures and the underlying impacts is crucial to improve the resilience of the community. Risk assessment and community participation in building a resilient neighborhood contribute to the development of the risk management sector of a country. Emerging technologies like web Dashboards using open-source software in risk assessment are widely used as it integrates the spatial data with related non-spatial data to understand the situation and aim to foster the communication through visualization. This study deals with designing, developing, and evaluating the risk assessment Dashboard for visualizing the cascading effects on the CI due to natural hazards like floods and landslides for a neighborhood in Medellin, Villatina. This study follows Human-Centered Design incorporated into Feature Driven Development (FDD) agile methodology. It illustrates quantification of impacts linked with the spatial impact of cascading effect on CI services due to the natural hazards using an open-source web dashboard.
