Hazards question plans
Impacts: What is most significant
Economic
Cost of rebuilding
Japan 2011 - $112 bn
Pinatubo - $700m
Haiti - $8 bn
Damage to industries
Japanese ports and japan was very exort and import dependent
Tourism suffered in Pinatubo after erruption, cost and lost economic potential = $7bn
Mt St Helens - 185 miles of highway was destroyed, ruined cars and machineary cost the agri industry $100m. Tourism and logging industries were damaged
Why are economic most significant
Lessens their ability to respond post event, if an economy is heavily damaged after an event it will decrease the amout of money a government has to spend on recovery
Infrastrucutre damage destroys long term growth, Haiti has more than 90% of debris uncleared after 10 years and killed FDI
Worse economic development makes social imapcts worse, Japan 2011 forced 15 ports to close and reduced supplies of gas and electricity
Economic impacts are more long term than social
Due to globalisation, economic impacts can have economic impacts in other countries arround the world, Japan 2011 port clossures caused supply chain problems in the automotive and electornic industry
Enviromental
Destruction of the physical enviroment
Pinatubo
Lahars caused errosion of river banks and flooding, causig bridges to collapse.
Ash falls and lahars destroyed 700km2 of forrest and agricultrual land
Mt St Helens
Ice on the top of the volcano melted and caused the water to unstabilise slope, large mudflows and flooding (lahars)
All trees within 30km of the volano were flattened
Lahars got into lakes and killed much of the life, 12 million fish
Why are enviromental most significant
Leads to economic impacts, destruction of farmlands (pinatub)
Leads to social impacts, loss of food soruce (Mt St Helens)
Can be on a larger spacial scale, Pintatubo erruption lead to a change in all global temperatures
Damage to enviroments and ecosystems often takes a long time to rebound and recover
Pollution
Japan 2011 - 5 million tonnes of waste created, mainly plastic, and much ended up getting washed into the ocean
Pinatubo - Ash clouds in the atmosphere lead to global temperatures falling by 0.5 degrees. 20 million tonnes of sulphur dioxoide released into the atmosphere
Social
Displaced people
Haiti - 1.5 million
L'Aquila - 70,000 and 30,00 rehomed in "tent cities"
Japan 2011 - 300,000
Pinatubo - 1.2 million lost their homes and had to migrate to Manilla
Loss of acess to services and essential goods
Deaths, most significant short run impact
Haiti - 220,000
Pinatubo - 850
Japan 2011 - 19,700
Why are social the most significant
Leads to economic impacts, people dies or moving lessens the economic abiliy of a country (Monserrat)
Short run impacts and long run impacts, deaths and loosing homes is short run but PTSD and trauma are long term
Takes a long time to recover
Social perceptions of a place are damaged after an earthquake, fewer tourists, especially bad for countries that depend on tourist, Turkey
Displaced people places additonal strain on services, people moving to Manilla after Pinatubo
Physical factors determine the impacts
Economic development determine the impacts
Economic development determines the mitigation
