Q

What are disaster risks? What are its cause?

A
  • potential damage to properties, injuries, loss of lives in (given period of time)

cause: interaction btwn tectonic hazard, vulnerability of ppl, exposure to hazard

LINK
factors determining how bad the risk is
1. type of tectonic hazard
2. vulnerability of ppl
3. exposure

given period of time, disaster dosent just disappear. Will have ash fallout, may trigger floods, may trigger fires lahars e.g.

A
  1. type of tectonic hazard
  2. vulnerability of ppl
  3. exposure

e.g. Tohuku
Possible disaster risk: coastline

Type of tectonic hazard: tsunami
Vulnerability of ppl: Moderate, people taught how to evacuate tsunami
Exposure: Sendai coastline, very high as buildings near coastline

Q

environmental consequences of disaster risks that happen (vague example)

A

landslide
- debris bury huge areas, forest
- flooding, kill aquatic life

disaster risks VS tectonic hazards
Tectonic Hazards + Vulnerability + Exposure = Disaster Risks

Explanation
Disaster Risks is what may happen during and after a disaster.

Reduced risk from disaster risk managment

Increased risk when ppl are more vulnerable (unprepared) and more exposed(e.g. Sendai is near Coast ppl hit badly in tsunami)

Q

social consequences of disaster risk that happen

A

landslides (debris, floods)

debris
- fast-moving -> injuries, deaths
- destroy houses, homeless -> temporary housing -> lack sanitation, bad QoL

debris -> block river -> floods
- contaminate clean, drinking water
- psychological trauma -> lose homes, loved ones, threat of physical harm, losing lives

Q

how is development of countries hindered by tectonic risks that happen?

A
  • govt. spend money repair facilities -> less development -> less invest education, healthcare, poverty reduction -> less economic growth (tourism, infastructure damage)
  • developing countries worst affect
  • ppl poorer, standard of living drop (no jobs, social services, faciltiies)

LINK
Tourists don’t come because of unforseen circumstances
- natural disasters (dangerous, infastructure DMG)

nature of hazard

A

i.e. duration of shaking, time of shaking

IS NOT:

Q

exposure earthquake vs volcanic eruption

A

earthquake
- population density
- distance from epicentre

volcanic eruption
- presence -> infastructure, ppl

21
Q

nature of hazard (earthquake)

how duration of shaking -> disaster risks -> damage done?

A

longer ground shaking -> more disaster risks -> more likely building collapse, ppl trapped

earthquake
- duration, time of shaking

22
Q

nature of hazard (earthquake)

how does time of shaking -> disaster risks -> damage done?

A

time of day, activities carried out diff. -> night, sleeping (disaster risk) -> unable evacuate quick -> ppl trapped

earthquake
- duration, time of shaking

23
Q

v__ conditions (earthquake)

how does q__, b__ d__ -> d__ r__ -> v__ c___

A

quality, building design -> disaster risks -> vulnerable conditions
- poorer quality design (disaster risk) -> more vulnerable collapse

  • ppl trap -> injuries, deaths

earthquake
- quality, building design
- soil, rock properties

24
Q

v__ conditions (earthquake)

3 characteristics of poor quality building design

A
  • poorly built, rigid low quality materials
  • dont follow building codes
  • lack earthquake-resistant features (i.e. cross bracing)
25
Q

building codes are set by…?

A

authorities

26
Q

what does it cause? s__ l__ and a__ s__ w__

how does s__, r__ p__ contribute to extent of disaster risks?

A

soil, rock properties
- worsen/cause, earthquake hazards

soil liquefaction
- buildings tip over, sink liquefied soil -> ppl trapped -> injuries, deaths

seismic waves hard rock -> soft soil, slow down, amplified
- more intense shaking -> more building collapse
- compact solid rock -> less intense shaking

Port-Au Prince, Haiti Earthquake

clarify
saturated soil = soil w/ lots of water content

27
Q

softer the soil, ___ the disaster risk

A

softer the soil,
higher the disaster risk

28
Q

exposure (earthquake)

how does p__ d___ affect exposure of people, belongings, infastructure

A
  • number of ppl/unit of area
  • higher population density, more exposed
  • more injuries, deaths

earthquake
- population density
- distance from epicentre

Papua New Guinea vs Great Sichuan Earthquake

29
Q

exposure (earthquake)

how does d__ f__ e__ affect exposure of people, belonging infastructure

A
  • nearer to city, greater no. exposed
  • city nearer = less energy of seismic waves absorbed -> rocks b4 reach city
  • violent shaking, building collapse, injuries, deaths

Port Au Prince vs Papua New Guinea

earthquake
- population density
- distance from epicentre

30
Q

nature of hazard (volcano)

how does c__ c__ of m__ affect volcanic eruption

A
  • chem. composition -> viscosity -> effusive/explosive eruption

Kiluea VS Merapi

volcano
chemical comp. of magma

31
Q

vulnerability of hazard (volcano)

how does a__ of s__, g___ affect vulnerability?

A
  • greater availibility groundwater -> lahars
  • vulnerability people, properties increased
  • injuries, deaths
32
Q

sources of large quantities of water that cause lahars

A

rapid melting, snow, ice (volcano summit)
groundwater released -> cracks, lines of weaknesses
rivers, lakes
heavy rainfall

Mt Pinatubo

33
Q

how p__ w__ c__ affect vulnerability to volcanic eruption?

A
  • distribution of ashfall, tephra
  • larger area ashfall, more vulnerability
  • heavier, larger particles deposited near volcano
  • finer ash particles -> thousands km away

i.e.

Human settlements Volcano Forest

Prevailing wind: Left = human settlements most affected
Prevailing wind: Right = wildlife most affected

Mt Pinatubo

34
Q

how does the d__ of f__ a__ p__ a__ p__?

A
  • people -> health, respiratory problem

  • destroy farmland

  • availibility of groundwater -> lahars
  • prevailing wind conditions -> tephra travel further

Mt Pinatubo

35
Q

exposure (volcano)

how does p__ -> i___, p__ affect disaster risks

A

presence -> infastructure ppl

Q

how does l__ u__ p__ reduce e___

A

rough idea
- control, minimise development -> high-risk area
- less potential deaths

how achieve
- hazard maps, past earthquake data -> risk areas -> suggest lvls of risk (likelihood/extent disaster occurence)
- strict guidelines
