Geography Test 1 Revision on, Types of hazards, Characteristics of hazards, Spatial Technology, Preparedness and mitigation

Hazard

occurs when forces of nature combine to become destructive and have potential to damage

Ecological Hazards

A biological or chemical hazard that has the potential to impact adversely on the wellbeing of people or on the environment more generally.

Natural hazards

Atmospheric, hydrological and geomorphic processes and events in our environment that have the potential to affect people adversely.

Atmospheric Hazard

Caused by climatic processes such as tropical cyclone storms and droughts

geomorphic

relating to the formation and shaping of landforms and landscapes by natural processes.

Hydrological Hazard

A risk posed by elements of water e.g. Flooding, Glaciers, Wave action etc.

Prepardness

Planning the interventions required to prevent the effects of a hazard e.g. education in school, early warning system

Mitigation

Implementation of strategies to severity of harm e.g. biulding zones, land use management

Hazard risk management

Process of identifying and controlling hazards that could cause harm to people before, during and after hazards

Spatial technologies

Are any software hardware used to help prevent/identify hazards e.g. remote censoring, GPS, drones

Forms of natural hazards

- Tropical storms

- floods

- landslides

- droughts

- bushfire

- earthquake

Forms of ecological hazards

- infectious diseases

- animal transmitted diseases

- water-borne diseases

- chemical hazards

Spatial

The arrangement of geological phenomen poor activities across earth's surface

Temporal

spread or pattern, a geological phenomenon over time

Frequency

It refers to how often a hazard event in a particular area

Magnitude

Strength of a hazard, or how large it is

Duration

How long has it lasts

Probability

Prediction that a hazard event will occur based on scientific observations.
