A multivariate event occurs when several hazards affect the same region at the same time.
A spatially compounding event occurs when several impacts occur at the same time but at different locations.
A temporally compounding event occurs when a series of hazards affects the same region, exacerbating the impact of any of the individual events.
A preconditioned compound event occurs when the impact of a hazard is exacerbated by pre-existing conditions.
