1. avoid, delay or prevent hazard events

2. 1.3 million

3. 110,000 troops deployed
bank of japan offered $183 billion to keep economy up
japan accepted aid from 20 countries

4. 60% of fishing fleet destroyed

5. 39K

6.
Secondary impacts result from the earthquake

Liquefaction occurs when surface rocks become more liquid during movement, buildings can sink

Landslides and avalanches are caused by ground shaking

Tsunamis can form from underwater earthquakes displacing a large column of sea water

Aftershocks are When the plates re adjust to their new positions small earthquakes may occur causing additional damage.

7. economic development led to rapid urbanisation and high population density
the poor live in coastal regions

8.
continental
oceanic

9. 7, shallow focus of 13km, epicentre only 24km from capital port au prince

10.
newly formed oceanic plates sink as they become denser

11.
movement of earth's surface

12. 19,000

13.
areas or countries which are exposed to numerous hazard, both hydro meteorological and tectonic eg Philippines

14. satellite image
GIS hazard mapping
early warning systems

15. plates move side by side

16.
seismometers

small earthquakes

changing volcano shape

pressure inside volcano

17.
heat produced by decay in core heat the lower mantle creating convection currents in the asthenosphere which act as a lubricant to the plates above

18. 101 million

19.
fractures in earth's surface by which ash, lava and gases erupt, either shield volcanoes, formed at constructive boundaries, or composite volcanoes., formed at destructive boundaries

More than 500 million are at risk of hazards from volcanoes

Since 1800, 260,000 people have died from eruptions

1900 volcanoes are considered active

20. in the carribean, with a volcano at its centre

21. tsunami which was responsible for the deaths and the destroyed nuclear power plant

22. education for people to be less vulnerable

23.
at destructive boundaries, the denser plate subducts underneath the less dense plate at the subduction zone causing earthquakes at the benioff zone

24.
the second waves, transverse, travel through solids, 60% slower than primary

25.
in the middle of plates where plumes erupt on the ocean floor forming a chain of volcanoes as the plate moves eg Hawaii
