- Types of Hazard
- Geophysical
- Earthquakes
- build up of tension between the tectonic plates
- releases energy
- measured on the richter scale, logarithmic
- can happen at all plate boundaries
- can cause tsunamis
- can happen at all plate boundaries
- measured on the richter scale, logarithmic
- releases energy
- build up of tension between the tectonic plates
- Landslides
- movement of soil or rock controlled by gravity
- heavy rain, soil erosion, earth tremors
- includes downward and outward movement
- associated with tropical storms, local storms, river floods
- includes downward and outward movement
- heavy rain, soil erosion, earth tremors
- movement of soil or rock controlled by gravity
- Tsunamis
- caused by earthquakes, tectonic movement
- series of waves
- also caused by volcanic activity and mass movement
- series of waves
- caused by earthquakes, tectonic movement
- Volcanic Activity
- happens at all plate boundaries except for conservative
- shield and composite volcanoes
- energy builds up in the magma chamber
- pyroclastic flows and what not
- volcanic winter
- pyroclastic flows and what not
- energy builds up in the magma chamber
- shield and composite volcanoes
- happens at all plate boundaries except for conservative
- Caused mostly by tectonic movements
- Earthquakes
- Hydrological
- Floods
- general floods can be predicted in advance except for flash floods
- often damage to property is the main impact
- floodline, website
- armed forces
- emergency services respond almost immediately
- local or nationwide media coverage depending on severity
- emergency services respond almost immediately
- armed forces
- floodline, website
- often damage to property is the main impact
- general floods can be predicted in advance except for flash floods
- Avalanches
- mechanical failure in a snowpack
- flowing snow and air
- can be due to melting snow
- engulfs anyone in its path
- can be due to melting snow
- flowing snow and air
- mechanical failure in a snowpack
- Tropical Storms
- cyclone, hurricane or typhoon
- water temp >27C
- can be predicted several days in advance
- wind walls
- calm eye
- clockwise in the southern hemisphere, anti-clockwise in the northern hemisphere
- calm eye
- wind walls
- can be predicted several days in advance
- water temp >27C
- cyclone, hurricane or typhoon
- Caused by water movements, water energy, precipitation, etc
- Floods
- Atmospheric
- Wildfires
- dry air
- high pressure
- hot hot hot
- low pressure can cause it to spread quicker
- hot hot hot
- high pressure
- dry air
- Drought
- destroys an area over time
- can last for many years
- affects agriculture and water supplies
- can lead to food insecurities, famine, malnutrition, epidemics and population displacement
- desertificatioo-nnnnnn
- can lead to food insecurities, famine, malnutrition, epidemics and population displacement
- affects agriculture and water supplies
- can last for many years
- destroys an area over time
- Tornadoes
- rotating column of air
- mostly in contact with the surface and a comulonimbu-s cloud
- rotating column of air
- Caused mostly by wind movements and the climate
- Wildfires
