hazard
(noun) A threat (whether natural or human) that has the potential to cause loss of life, injury, property damage, socio-economic disruption or environmental degradation.
hazard event
(noun) The occurrence (realisation) of a hazard, the effects of which change demographic, economic and/or environmental change and/or environmental conditions.
geophysics
(noun) the study of the rocks and other substances that make up the earth and the physical processes happening on, in, and above the earth
natural hazard
(noun) An extreme geophysical process which can occur naturally in any part of the world and which has the potential to cause loss of life, damage to infrastructure and disruption to human activity.
tectonic hazard
(noun) A natural hazard created when the Earth’s crust moves (e.g. tectonic plates collide into each other). This includes earthquakes, volcanic eruptions and tsunamis.
geomorphological hazard
(noun) A natural hazard originated at or near Earth’s surface. This includes river and coastal flooding, landslides and avalanches.
atmospheric hazard
(noun) A natural hazard associated with Earth’s atmosphere, such as tropical cyclones, severe storms, tornadoes, wildfires and drought.
biological hazard
(noun) A natural hazard driven by biological processes. This includes various types of disease, including infectious diseases
Subsidence
(noun) the process by which land or buildings sink to a lower level
natural process
(noun) a process existing in or produced by nature (rather than by the intent of human beings)
natural disaster
(noun) A major hazard event that causes widespread disruption to a community or region, with significant demographic, economic and/or environmental losses, and which the affected community is unable to deal with adequately without outside help.
unprecedented
(adjective) never before known or seen, without having happened previously
inundation
(noun) a flood, or the fact of being flooded with water
infrastructure
(noun) the fundamental structure and facilities that an area needs, such as roads, electricity, buildings
magnitude
(noun) the size of a geophysical hazard event and is measured by the amount of energy or the amount of material produced by the event
volcanologist
(noun) a scientist who studies volcanoes
Saffir-Simpson Scale
(noun) A scale that classifies hurricanes according to wind speed, air pressure in the center, and potential for property damage.
aftermath
(noun) the period that follows an unpleasant event or accident, and the effects that it causes
frequency
(noun) the number of hazardous events of a certain magnitude that occur over a given period of time
fluctuations
a change, or the process of changing, especially continuously between one level or thing and another
fault
(noun) a crack in the earth’s surface where the rock has divided into two parts that move against each other:
likelihood
(noun) probability, chance that something will happen
human vulnerability
(noun) the degree to which people are susceptible to loss, damage, suffering and death, in the event of a disaster
exposure
(noun, in the context of human vulnerability) the nature of the area in which people live - how hazardous it is
