Lecture # 2 Hazards Of Geo

Front 1

why is it hard to maintain databases for diaster events?

Back 1

1. disasters can co-occur eg hurricane causes floods

2. mortality can be hard to count

3. general lack of census if developing countries

Front 2

4 things for defining a disaster

Back 2

1. 10 or more deaths per event

2. 100 or more ppl affected injured or homeless

3. government declaration of a diasaster

4. plea for international assistance

Front 3

what are two exceptions for the CRED diaster threshold?

Back 3

1. for drought or famines at least 2000 persons affects

2. for tech diasasters 5 or more deaths per event

Front 4

what is absolute data?

Back 4

# of casualties, billions of dollars in damag etc

Front 5

t or f? stats must be placed in a community and regional context?

Back 5

true 10 deaths in a city of 200 is differnt from 10 deaths in a city of 200 000.

Front 6

4 things the media tends to concnetrate on?

Back 6

1. human interest

2. visual impact

3. evtns close to home

4. NA perspective

Front 7

t or f? earthquaks tend to cuase more death and flods affect more people for homelessness but have fewer casualties ?

Back 7

true

Front 8

t or f? drough lead only to economic losses from agriculture in developed countries but lead to famine in developing countries?

Back 8

true

Front 9

4 things that cause most disaster impacts to have increased over time?

Back 9

1. property damage

2. economic losses

3. persons affected

4. deaths globally

Front 10

where did the Haiti earthquake occur?

Back 10

along a transform fault, side by side movement.

Front 11

did co-diasters occur in Haiti?

Back 11

yes landslides affected many pepole in the slums

Front 12

2 reasons why the land impacted Haiti greatly with the earthquke / landslides?

Back 12

1 land pressure , 1 biollion people lie on degraded land worldwide

2. poverty and lack of land availabulity leads to unsustainable farming practices such as soil erosion, clear cutting monoculture

Front 13

human foot print?

Back 13

moving from rural to urban areas, slums are quickly growing around the cities and some areas people are building in increase risk zones

Front 14

difference between resiliency and reliability?

Back 14

resiliency? rate of recovery from the occruance of an event, Haiti has very poor resiliency

realiability: frew with which protective devices against diasasters are able to withdatnd the diasaster.

both of these are lower in developing countries.

Front 15

risk?

Back 15

invovles estimating the likelihood that a particular event will harm human health

Front 16

risk management?

Back 16

deciding wheather or how to reduce a particular risk and at what cost

Front 17

risk is viewed by people as?

Back 17

subjective

Front 18

stats analysis formula for risk?

Back 18

R = prob x loss (economic or health)

Front 19

property loss 0 , 10 000, 50 000 and 100 000.

prob = 0.95 .030 .015 and .005

what is the total overall property loss risk?

Back 19

1500

0 x .95 = 0

.03 x 10000 = 300

etc

Front 20

can we do the same for death risks?

Back 20

yes we can

Front 21

how do we use risk analysis for event trees?

Back 21

we multiple all the proabilities together to get our final answer

Front 22

what aer the two factors for overall realiability of a technological system?

Back 22

system reliability = technology reliability x human reliability

Front 23

nuclear power plant has 95 % tech relaibility and 75% human what is the over system realiability?

Back 23

.71 or only 71%.

Front 24

why is the greatest risk factor leading to a reduction in life expectancy ____? and it is linked to what 4 things?

Back 24

poverty and it is linked too

1. malnutrition

2. increased suseptibility to fatal diseases

3. lack of access to health care

4. contaiminated water supplies

Front 25

what are 3 indirect benefits of reducing poverty?

Back 25

1. stimulates economic growth

2. reduced environment degradation

3. improves human rights

Front 26

are risk perceptions received well by people?

Back 26

nope 1 in 2 premature death from smoking, 1 in 60 for motorbike accident yet people are worried about getting west nile which is 1 in a million or a plane crash which is 1 in 9 million

Front 27

3 ways in wich we can become better at perceiving risks?

Back 27

1. carefully evaluate media

2. compare risks

3. cocn n the most serious risk to your own health and dont worry about risks you do not have control over

Front 28

t or f? there has been a shift in the nature of risks; shift from infectious diseases towards chronic degenerative dieases

Back 28

true

Front 29

hi

Back 29
