What is a natural hazard?
A natural occuring process which has the potential to affect people
1 of 20
What is a natural disater?
A natural hazard actually occuring causing deaths and damages.
2 of 20
What is a natural event?
A natural occuring process which happens un hunhabited areas.
3 of 20
What are the top 6 global killers?
Volcanoe, Hurricane, Earthquake, Flood, Drought, Landslide
4 of 20
when does a hazard become a disater?
when a hazardous geophysical event meets a vulnerable population
5 of 20
What are the vulnerability factors?
Urbanisation, Political change, Economic growth, Globalisation, Technological innovation, Poverty, Climate change, Population change, Land pressure
6 of 20
what is a hydro-meteorlogical hazards?
a hazard that involves water or the weather e.g floods and hurricanes
7 of 20
what is a geophysical hazard?
a hazards cause by earthprocesses either through tectonic or mass movent of rock and land
8 of 20
What is the disater risk equation?
frequency or magnitiude of a hazard x vulnerability/ capacity to cope
9 of 20
Define frequency
how often an event occurs
10 of 20
Define magnitude
the size of an event
11 of 20
what is meant by a 'busy year'
frequent high magnitude disasters
12 of 20
name all 6 disaster risk discs
preparedness, responce, recovery, mitigation, development, adaptaion (to climate change)
13 of 20
give an example of a local geophysical disater
Market risen earthquake, 5.2 magnitude, biggest in 25 years, caused powercuts, epicenter was in linchonshire,19 year old in barnsley crushed by a chimmeny, structural damage
14 of 20
give an example of a local hydro-meteorlogical disaster
sheffield floods 2007, i month rainfall in a week, 2 deaths, m1 closed, medowhall flooded, pople evacuated and air lifted,loss of buisnesses
15 of 20
Name the causes and distribution of draught
Long continous period of little rainfall, late/no monsoon, occur in semi arid areas effecting 40% of land and 70% population
16 of 20
Name the causes and distribution of floods
excessive rainfall, an intense rainfall event, rapid snowmelt- mostly occurs costal areas and those surrounded by rivers, effect 82% population
17 of 20
Name the causes and distribution of landslides
large amounts of rainfall or earthquakes, mainlt located in mountanous areas of certain rock types and permiability- effects 5% of the population
18 of 20
Where are volcanoes and earthquakes mainly distributed
along plate bountries/ fault lines
19 of 20
identify the characteristics of a hazard hotspot
an area at risk of both geophysical and hydro-metorlogical disaster that are vulnerable or have a low capacity to cope
