Which hazards are most threatening?

So which hazards are most threatening to a population?

• It is either scale, surprise or extended period that creates the bigger threats to communities.

• The size of flood or Earthquake or Tsunami

• The lack of warning of the earthquake or landslide or tornado

• The duration of flooding or a of storm or of a drought

• Or the complex nature of the event

All of these can breach the threshold of prepared coping mechanisms

In the short term is has always been the Earthquake within a concentrated area that causes biggest devastation not only to infrastructure but to the population also. The less frequent Tsunami can equally cause high casualties but over a larger limited area of a coastline.
