- Hazards
- Types
- Meterological (Weather)
- Storms
- Drought
- Floods
- Geo-morphological (Changing shape of the earth)
- Landslides
- Avalanche
- Wildfires
- Geological (Rocks)
- Earthquakes
- Volcanoes
- Meterological (Weather)
- Risk
- To people
- Death, injury,disease, stress
- To goods
- Economic loss, infrastructure damage, property damage
- To the enviroment
- Pollution, loss of flora, fauna and amenty
- To people
- Classification
- Hydro meteorological
- Geophysical
- El Nino
- Changes in the circulation of cold and warm waters
- Human factors
- Rapid population growth
- Pressure on land
- Growing number of extra vulnerable people, e.g. the elderly
- Deforestation/land degradation
- Causes flooding, desertification and soil erosion
- Destruction of natural defenses, e.g. mangroves
- Urbanisation
- Development of squatter settlements (at risk of flooding and landslides)
- Poverty
- Higher death toll
- LEDC's are unable to afford to prepare
- Poor education - unable to have access to tehnology
- Inability to get aid to remote areas due to poor infrastructure
- Politics
- Corrupt governments may misuse resources, or prevent the use of internation aid
- Rapid population growth
- Trends
- Analyisis
- Can be disrupted by mega disasters
- Number of reported disasters are increasing
- A more globalised world means access to an improved IT
- Increasing population means an increase in vulnerable people
- Analyisis
- Case studies
- California
- Impacted by the El Nino Southern Oscillation
- The most hazardous zone is concentrated along the San Andreas fault
- Example - Earthquakes
- Causes - Network of active faults lie under Los Angles and San Fransico
- Impacts - Soft basin sediments in LA lead to rapid shaking. 5 major earthquakes were recorded in the last 100 years.
- Causes - Network of active faults lie under Los Angles and San Fransico
- Philippines
- Lies in a belt of tropical cyclones
- Near an active plate boundary
- Oceanic Philippines plate is being subducted beneath the Eurasian plate
- Tropical monsoon climate
- Population density of 240 people per km2
- Average of 10 typhoons a season
- Example - Tropical storm Thelma
- Impacts - Killed a total 35,983, injuring a further 29,178, leaving 6.25 million homeless with $9,018,574 worth of damage
- UK
- One of the mist hazard-free parts of the world
- Example - Shropshire, UK
- Tenbury Wells - Flash flooding, 2007
- North Shropshire - Great droughts in 1959, 1976, 2003
- Shrewsbury - Earthquake, 1896, 1995
- California
- Types
- Inability to get aid to remote areas due to poor infrastructure
- Corrupt governments may misuse resources, or prevent the use of internation aid
