Flow chart illustrating how a requirement for long-term hazards is created in the context of best-practice recommendations of VOBP3. In this and subsequent flow charts, ovals are starting points and major outcomes (which, in the case of probabilistic forecasting also includes processes such as expert elicitation and even-tree analysis), squares are processes, diamonds are major decisions and the cylinder represents a database. Solid boundaries indicate observatory-based processes, dashed boundaries are partner-organization-based processes (understanding that some observatories lie within university organizations and that in some processes are shared, as indicated by solid and dashed lines)
