Natural disasters occur when natural hazards such as floods, hurricanes, earthquakes interact with human and built environments. Hazards become dangerous when they threaten humans or destroy infrastructure. The frequency of earthquakes of different magnitudes follows a general pattern, with smaller quakes occurring more often than very large ones. New Zealand has experienced several significant natural disasters in its history, including landslides, earthquakes, and volcanic eruptions.

2. • A natural disaster is when the earth's creats hazards. These
are like floods, tornados, hurricanes, volcanic
eruptions, earthquakes, heatwaves and landslide. They can
lead to financial, environmental or human losses. If these
disasters continue it would be a great danger for the earth.
This understanding is concentrated in the formula:
"disasters occur when hazards meet vulnerability."

3. • A natural event becomes a hazard when it
threatens humans and the built environment.
Natural events like earthquakes can become a
hazard when builds are destroyed or when
people can be potentially injured.

4. • hurricanes, tornadoes, tsunamis,
typhoons, volcanic eruption,
avalanche,blizzard, drought, earthquake,
heat wave, flood, famine, landslide,
sandstorm, wildfire, an impact of a
meteor, comet etc , limnic eruption

5. • Magnitude Rule of Thumb
• 4.0-4.9 --------- 1 per day
• 5.0-5.9 --------- 2 per month
• 6.0-6.9 --------- 2 per year
• 7.0-7.9 --------- 1 per 3 years
• 8.0 or over ----- 1 per century

6. • 1846 Taupō landslide
• 1855 Wairarapa earthquake
• 1868 Great storm
• 1886 Tarawera eruption
• M 8.2, Wairarapa, January 23 1855

7. • A place can be vulnerable to earth
quakes because they could be between
two tectonic plates. These plates are
moving and can cause earth quakes.
Countries that are quite flat con be
flooded easily as torrential rain may not
be able to drain off as quickly as it came.
