0

Base isolating bearing

Steel/rubber shock absorbers in foundations

1

Building regulations/codes

Laws enforced to prevent unsafe building design

2

Cholera

Bowel infection which can be fatal from contaminated food/water

3

Cross braces

Diagonal steel bars to prevent deformation of walls

4

Dampers

Large weights, controlled to counteract movement

5

Earthquake

Sudden trembling or shaking of the earth

6

Emergency response

Fire, police and ambulance services

7

Epicentre

Location of earthquake at Earth's surface above focus

8

Fault line

Fracture in rock caused by stress

9

Focus

Location of the earthquake within the crust

10

Hazard

Events causing loss of life, injury, disease, economic damage

11

High-tech companies

Research/production of computers/communication system

12

Inertia

Resistance to movement or change

13

Infrastructure

Services; transport, airports, schools, emergency services

14

Intensity

Degree of shaking at ground, measures damage caused

15

Liquefaction

Shockwaves cause water to rise, ground becomes unstable

16

Load capacity

Designed capacity of building to support a given mass

17

Long-term aid

Improve quality of life, providing housing, medical, schools

18

Magnitude

Size of the earthquake using Richter scale

19

Monitoring

Constant measuring of earthquake activity, small/large

20

Preparation

Planning for earthquake; education, emergency services

21

Prevention

Designing buildings/infrastructure from damage

22

Probability mapping

Mark percentage possibility of an area experiencing an earthquake

23

Reconstruction

Long-term rebuilding of houses, infrastructure, industry etc.

24

Recovery

Medium-term; reopen schools, clear roads, shops open etc.

25

Retrofitting

Adding structures to existing buildings to improve structural safety

26

Richter scale

Measures earthquake magnitude, logarithmic scale

27

Seismic

Shaking displacement caused by earthquake

28

Seismic waves

Vibrations caused by earthquake

29

Seismologist

Scientists who measure and research earthquake activity

30

Short term aid

Emergency response; rescue, treat, feed, house etc.

31

Tectonic hazard

Earth hazards (earthquakes/volcanoes) interact with people
