Natural hazards and emergencies

Tornado hazards

Tornadoes occur infrequently in Auckland but are much smaller than those that occur in the Midwest of the USA. 

They typically have narrow and short tracks about 10m to 30m wide and between 1km and 5km long. 

They are impossible to predict because of their small size, short lifespan and tendency to form offshore so people in a tornado's path are highly vulnerable to injury. 

Most tornado injuries or deaths in Auckland are related to airborne debris or building collapse.

 


Tornado damage

In Auckland, while tornado damage generally is localised, tornadoes have caused damage to:

  • buildings and power lines
  • fences and trees
  • vehicles by overturning or wind or hail damage
  • injuries to people but rarely death.
