Example of how MYRIAD-HESA operates without a time-lag. This figure shows both hazard pairs and hazard groups. (a) Hazards are a hazard group if all hazards overlap with each other in space and time as a pair. Here, there are two hazard groups, which are referred to as Events. Event 1 is encompassed by the black solid line, while Event 2 is encompassed by the black dashed line. Event 1 consists of three hazard pairs between Hazard 1, 2, and 3. Event 2 consists of one hazard pair between Hazard 3 and 4. (b) A dynamic hazard has to overlap with the other hazards during at least one of the overlapping time-steps. Here, Hazard 1 is a dynamic hazard. Therefore, it’s event polygon can change over time. Hazard 2 and Hazard 3 are not dynamic hazards. Their polygons remain the same between their start time and end time.
