Question

Why are hurricanes considered more damaging than tornadoes when tornadoes have stronger winds

Answer 1

-- A tornado follows a path that's a few miles wide, for a few hours.
   Then it's all over.

-- A hurricane follows a path that's several hundred miles wide,
   for a week or two, before it's over.
   Then comes the rain, continuing on the same path, for another week.

Answer 2

Hurricanes are larger and slower and cause damage by flooding and wind damage
