Avalanche
A mass of snow, ice and rocks falling rapidly down a mountainside
1 of 27
Capacity to Cope
A combination of all the strengths and resources available within a community that can reduce the risk or the effects of a disaster
2 of 27
Chronic Hazard
Such as global warming, and El Nino/La Nina, that may increase the threat of other environmental hazards such as increased sea level rise leads to flood risk
3 of 27
Context Hazard
Widespread (global) threat due to environmental factors such as climate change or the eruption of a supervolcano
4 of 27
Convection Current
The transfer of heat by the mass movement of heated particles into an area of cooler fluid
5 of 27
Crust
The outer layer of the Earth between the surface and the mantle, between 0-60km thick
6 of 27
Cyclone
A large scale atmospheric wind and pressure system characterised by low pressure at its center and by circular wind motion, counter clockwise in the N. Hemisphere and clockwise in the S. Hemisphere
7 of 27
Disaster
A hazard becoming a reality in an event that causes deaths and damage to goods/property and the environment
8 of 27
Drought
A long period of abnormally low rainfall, especially one that adversely affects growing or living conditions
9 of 27
Earthquake
A sudden movement of the Earth's crust caused by the release of pressure accumulated along geologic faults
10 of 27
Flood
An overflow of a large amount of water, beyond it's normal limits, especially over what is normally dry land
11 of 27
Geophysical Hazard
A hazard formed by tectonic processes, e.g. volcanoes, earthquakes, landslides, avalanches
12 of 27
Global Warming
A rise in the average surface temperature of the planet
13 of 27
Greenhouse Gas
A gas that contributes to the greenhouse effect by absorbing infrared radiation
14 of 27
Hazard
An event that is perceived to be a threat to people, property and nature
15 of 27
Hydro-Meteorological Hazard
A hazard formed by hydrological and atmospheric processes, e.g. cyclones, droughts, floods
16 of 27
Landslide
A collapse of a mass of earth of rock from a mountain or cliff
17 of 27
Lava
Hot molten or semi-fluid rock erupted from a volcano or fissure, or solid rock resulting from cooling of this
18 of 27
Lithosphere
The crust of the earth around 80-90km thick
19 of 27
Low pressure system
A whirling mass of warm moist air that generally brings stormy weather with strong winds
20 of 27
Magma
Molten material that rises towards the Earth's surface when hotspots within the asthenosphere generate convection currents
21 of 27
Mantle
Portion of the Earth between the crust and the core made up of magma around 2900km thick
22 of 27
Physical Risk
The likelihood of a given physical hazard
23 of 27
Disaster Risk Equation
The risk of disaster increases as the frequency or severity of hazards increases, people's vulnerability increases and people's capacity to cope decreases
24 of 27
Tectonic Plate
Massive, irregularly shaped slab of solid rock, composed of continental and/or oceanic lithosphere, that moves slowly across the asthenosphere
25 of 27
Volcano
A typically conical mountain or hill that has a crater or vent through which lava, rock, vapour and gas erupt from the Earth's crust
26 of 27
Vulnerability
A high risk combined with an inability of individuals and communities to cope
