Deggs model states that a disaster will only occur if a vulnerable population is exposed to a natural hazard
Hazard risk equation - risk = (vulnerability x hazard)/ resillience
vulnerability = ability to anticipate, cope with and recover from a hazard
resilience = the ability to protect from destruction
disasters occur when there is significantdamage to SEEP factors
the relationship between resilience and vulnerabilty is important as it determines the risk and the capacity to cope
Richter Scale - absolute scale meaning wherever the EQ is recorded it will measure the same on the Richter Scale. Logarithmic = increase of an index means that the EQ is ten times a powerful.
Mercalli - measures the experienced impacts of an EQ - askspeople how much they felt the shaking and uses key indicators e.g., how much furniture was shaking. Relative scale as people experience different amounts of shaking
MMS - describes EQ in terms of energy released. Calculated from the amount of slip on the fault and the area impacted. - more modern than the Richter scale
VEI - relative measure of explosiveness. Calculated from ejecta, height of the eruption and qualitative observations. Logarithmic scale
MMS - measures seismic moments
Richter Scale measures amplitude of wave
