State the process of a Hurricane:
- Ocean reaches 26c
- Water vapor rises and evaporates
- The water vapor condenses into clouds
- Wind starts blowing circularly and gains clouds.
- Once the winds reach 124mph (200kmph) it is considered a cyclone.
- Cyclone reduces in size when it travels over land.
What is the process of Liquidfaction?
- Due to shaking the soil loosens
- Liquid rises and the soft surfaces act like a liquid.
- CHCH is built on soft land so it had a bigger impact.
What is the process of Subsidence?
What was the impacts?
- Shaking results in the land rising or sinking.
- Ground cracks and creates flood hazards.
- Port Hills had up to 45cm uplift.
- 86% of eastern CHCH sunk
- up to 18cm of sinking.
State the process of an earthquake:
The tectonic plates are always moving. Occasionally the plates catch and build up energy. When the plates finally release shock waves are sent out (An earthquake).
The Blitz Bombing:
- How many deaths?
- How many tons of rubble?
- How many nights of bombing?
- 40,000 deaths
- 750000 tons of rubble

- How many tons of silt?
-1st= Mg 7.1 2nd= Mg 6.3 -185 people -At 12.51pm (city populated), 5km shallow so high peak ground acceleration, on major fault lines (after shock of nov4th) -200,000 tons
