The aim of this report is to present the first iteration of the use cases for business and critical infrastructure stakeholders, looking at Earthquake Early Warning (EEW) and Operational Earthquake Forecasting (OEF). It also provides an initial assessment of their potential use as part of an organisation’s internal Rapid Response to Earthquakes (RRE). RRE refers here to an organization’s internal disaster management, business continuity and resilience planning. This deliverable does not look at the wider community (e.g. citizens and first-responders), which has been covered in D1.3. The use-cases are intended to inform the development of the TURNkey FWCR (Forecasting, Early Warning, Consequence prediction, Response) platform. To this end the report: Presents the background and context to the TURNkey project; Describes the use-case development process, including its relationship to the participatory action research programme; Describes a fieldwork scenario used with the business and critical infrastructure stakeholder groups to identify the user requirements of the use-cases; Presents initial use-cases for EEW and OEF systems (including an initial assessment of the potential of their use as part of an organisations internal RRE, that is, their internal disaster management, business continuity and resilience planning). Identify the potential drivers and barriers to the implementation of EEW and OEF systems; Outline the next stages in the development of the use-cases; and Summarises the key issues that need to be considered by the TURNkey project partners as they develop and validate the prototype FWRC platform.

The review presented in the report should be considered a DRAFT work in progress.
