What is the difference between a hazard and a disaster?

• A disaster may cause harm; a hazard does cause harm.

• They are two different words for the same thing.

• A hazard has potential to cause harm; a disaster does cause harm.

• Hazards are cause by the atmosphere; disasters are caused by internal processes.

A catastrophe is

• a very large disaster with thousands killed that requires a major emergency response.

• a small hazard that only impacts a couple of people.

• not a big deal.

• the same as a disaster.

A magnitude increases, frequency

• increases

• decreases

• stays the same

The recurrence interval (return period) is

• the absolute time between events.

• completely useless.

• only for landslides.

• the average time between events of a specific size in a specific area
