Dregg's model states that there are two factors, size of the hazard and the vulnerability of the population. If the magnitude of the hazard is large, such as a magnitude 9 earthquake, but there is little infrastructure of population density near the epicentre, then no one will experience the hazard and the disaster is small and weak. Therefore if an earthquake has a magnitude of 6 but was situated in the middle of a city, this would be a greater disaster than that of a magnitude 9 in the middle of the ocean as more people would be impacted.
