Define 'frequency' in the context of disaster characteristics.

• A. The geographic spread of the disaster.
• B. The height of the disaster.
• C. How often a disaster occurs.
• D. The duration of the disaster.

Answer: (C)

Frequency is about how often a disaster occurs within a given time frame. In disaster characteristics, it helps us understand the regularity of events—how many times a type of disaster happens per year, decade, etc.—which informs risk planning and preparedness. For example, if floods happen three times in a year, that’s the frequency for that period. This differs from geographic spread, which describes the area affected by the disaster (the extent or reach), and from duration, which describes how long the event lasts. The option about height isn’t a standard metric for disaster characteristics.
