Christ Church New Zealand and aftershock Physical:• The earthquake struck on 4th September 2010• 7.1 on the Richter scale• 22nd February 2011 and after shock struck Christ
Church registering 6.3 on the Richter scale• The aftershock was 5km in depth of focus• It happened at12:51pm causing more deaths
Social:• Nobody died in the first instance• 181 people died as a result of the aftershock
Environmental:• Canterbury plains are made up of alluvial sediments
have a large water storage units so the earthquake caused significant liquefaction

million of which in Port Au Prince• 60,000 people migrated from the capitol of Port Au Prince• ¼ of civil servants dead• Environmental• 20 million m³ of rubble on the ground less than 5% has been
cleared
Economical• $5.8 billion dollars’ worth of damage• A lot of corruption and lack of knowledge of which
people own land meaning no new houses can be built
• Port au prince is a very vulnerable capitol as building regulations are inadequate and it is over crowded
• 4000 schools were damaged• 1/5 of jobs were lost due to the earthquake• The international airport was unusable as power
controls were damaged• Management• In September 2011 one million people living in
temporary housing• 87% of homeless people are still in the temporary
housing• Within 24 hours a medical team from Iceland had
landed• 50 Chinese people followed to act as another
medical team• British search and rescue teams reached Haiti 5
days after the earthquake
Volcanic Examples• Evacuation>>5,000 residents of Montserrat were evacuated 3 times
between December 1995-August 1996 (63% of the population)• Hazard resistance design>>People in Hawaii have timber houses• In Iceland during the Heimaey(1973) they used 6 million cubic metres of
water to spray on the lava to avoid shutting the harbourExtrusive activity:• Geyser>>Strokkur geyser, Iceland• Hot Spring>>Beppu Japan• Fumaroles>>Four peaked Volcanoes Alaska• Boiling Muds>>Fountain paint pots (Yellowstone National Park)America

Montserrat volcano Background:• LEDC• Part of the British Colony• Caribbean tourist hotspot
Physical:• Early activity like ash emissions, steam explosions and numerous
earthquakes• The steam and ash reached heights of 2500m• March 1996 huge ash cloud and pyroclastic flow happened• The climax occurred on the 25th June 1996 4.5 million m³ of ash
erupted from the volcano• 11th February 2009 40 million m³ of rubble from the north eastern
portion of the lava dome collapsed
Social:• A lot of post-traumatic stress disorder• The pyroclastic flow killed 19 people• Between 1995-1999 the population decreased from 10,000 -3,000
growing back to 5,000 after 2006• Silicosis a lung disease effected a lot of people
Environmental:• Only 40km² out of 100km² was safe to live on• The southern island was completely destroyed• The eruption in 1995 effected 63km around the island• 1/3 of the tropical rainforests were damaged• The soil was enriched with volcanic ash• Feral farm animals like cows have caused problems in the exclusions
zones destroying native species
Economical• Plymouth was eventually buried in over 10m of ash and mud
and the airport and docking facilities were destroyed• The construction a new airport cost £11 million known as
Gerald’s 2005• 1,500 people flocked to the island looking for jobs as they
were construction workers• Enrolment in all schools dropped from 2,672-620 between
1996-1998• 300 fulltime farmers lost their land as a result of the
explosions• Montserrat is now dependant on food imports• In 1997 annual tourists were at 4,000 when they should have
been 15,000• 400 students left the medical school (American University of
the Caribbean)• Money has also been invested into attracting new sets of
tourists to the Caribbean like families or travellers not just newlyweds or nearly deads
Management• They set up temporary shelters to the North• 7,000/01,000 inhabitants left for the UK or Antigua• A new observatory centre has been set up in Montserrat• UK government spent £100 million assisting migration• Stations with infra-red sensors which detect air pressure
which are set of as a result of eruptions have been set up• 2004 a 5 million grant from the UK was given by a
organisation called international development to build more hotels to boost the tourist industry again
• 2,000 new homes built as most of the population is still in temporary accommodation
Mount Etna Background:• Europe’s largest volcano• The mountain was 2368m high• One of the most active volcanoes in the world• Calderas surrounds Etna• Collision of the African and Eurasian >continental platesPhysical:• Eruption 14th December 1991
Environmental:• Effusive lava flows lasted 473 days• Lava destroyed the springs which provided the water supply for Zafferana
Economical:• Insurance claims ran into millions• Vineyards and chestnuts orchards were destroyed• Only one house was destroyed• Tourist industry boomed once the volcano was safe to visit• 25% of the population lived on the slopes of Mount Etna meaning they had to move• Ski station at Piano Provenzana was destroyed by lava flows
Management:• They constricted earth barriers perpendicular to the flow direction diverting 30% of the lava flow they did by using
concrete blocks to halt lava flow and then managed to dig a diversion channel• They sourced explosives to disrupt the lava flows away from Zafferana• The earth barrier built in 1992 was 400m long and 20m high managed to contain the lava for a month• US Marines operated the explosives
Mount Pinatubo Physical:• Typhoons created Lahars and flooding • 1991• Massive tropical storm of Yunya caused the
lahars
Economical:• 1,000,000+ farm animals died, many
through starvation. • 650,000 workers lost their jobs.
Social:• Disease spread quickly, Malaria, Chicken Pox
and diarrhoea. Also heavy treatment for respiratory and stomach disorders.
• 700 deaths: 6 as a direct result, 600+ from disease and 70 from drowning in lahars. 94% of the deaths were from the Aeta tribe. There were unaccustomed to being surrounded by modern day diseases and food. It was mainly children that died as a result of disease (Eg. Measles)
Environmental:• Ash cloud and sulphur compounds shielded
the Earth from the sun’s rays; the global temperature was reduced by 0.5Vc.
Management:• Some Indigenous Aeta tribe displaced. 58,000
people evacuated. • Philippine Institute of volcanology and seismology
(PHIVOLCS) was alerted when small steam eruptions were seen. Also USGS (United States Geological Survey) were called in to monitor the eruption and attempt to predict the activities.
• 7 seismic stations set up surrounding the volcano by May. (They were linked back to the Pinatubo Volcano Observatory (PVO) which had been set up on Clark Air Base).
• SO levels monitored every day. Closer to eruption, շup to 5000 tonnes were emitted every day. Measured by a COSEC machine.
• Deposit samples taken from previous eruptions. Tree remnants found showing only a previous 4/5 eruption in 2000 years. (Few eruptions usually mean they are more violent when they do happen).
• Alert Level 1 Small scale evacuations, villages within 10km of summit were evacuated. Expensive equipment removed from Clark Air Base.
• Alert Level 3 Predicted within 24 hours. 120,000 people evacuated from a 10 mile radius. By 10th June, nearly all of Clark Air Base was evacuated. Evacuation radius now extended 30km.
Nyiragongo Background:• Located in the Virunga mountains within Democratic
Republic of Congo.• Associated with the African rift valley.• 20km north Goma, just West of the Rwandan border.• 2002Physical:• Beneath Nyiragongo, the African plate is splitting apart
creating a rift valley.• Very fluid alkaline magma rises up through the gap
created by the rifting. • The magma that erupts from Nyiragongo has a low silica
content and can flow at speeds of up to 60mph.
Social:• 120,000 homeless• 147 people were killed• Eye irritation, respiratory problems and diseases caused
by contaminated water and fumes• Looting from abandoned homes and petrol store which
exploded, killing looters.Environmental:• 13km fissure opened in the south of the volcano• Lake Kivu, a major source of drinking water, was polluted
by sulphuric lava.• High temperatures caused fears of toxic gases releasing
from the lake bed. •
Economical:• From this lava formed a 600m wide, 2m deep
stream that reached Goma in a few hours, causing fires
• This destroyed 4500 (15%) of Goma’s buildings• Infrastructure, including communications and
transport links, was destroyed• Goma airport was partially covered in lava• Unemployment due to destroyed businesses
Management:• UN bring in humanitarian aid 2 days after eruption.• Rations included high energy food e.g. biscuits.• UN also set up refugee camps at a cost of $15
million (Repair cost was even higher)• Medical attention required – treatments for smoke
and fume inhalation. • Because advanced warning systems from wealthier
countries meant the population was warned in advance.
• The city of Goma was damaged, but was far enough from Nyiragongo to allow evacuation.
• If the eruption had happened 100 years ago, before organisations like the USGS, the death toll would have been much higher.
Puyehue-Cordón Caulle Background:• Puyehue volcano has a 2.4 km wide summit
caldera• The Cordón Caulle geothermal area has a 6
by 13 km wide depression and is the largest active geothermal area in the Andes
Physical:• Eruption began on the 4th of June, 2011.• It was caused by the Cordon Caulle, not
Puyehue• The ash cloud reached 12km high• 230 earthquake tremors occurred in one
hour• Social:• 3,500 people were evacuated
Environmental:• Sulphur and other gases were emitted• An estimated one hundred million tons of
ash, sand and pumice were ejected• The eruption produced lightning and strong
storms and some power cuts• The temperature of the Nilahue River rose
to 45 °C and killed an estimated 4.5 million fish
• Economical:• Bariloche, Buenos Aires, Neuquén and Melbourne
airports were closed due to ash• 4.5 million fish dead had a big impact on the fishing
economy• The cattle economy was also damaged• The ash cloud led Argentina to declare a state of
emergency for farmers as the eruption continued to effect the 2 million sheep that graze in Chubut
• Macquarie Equities placed the cost of disruptions to airlines at $21 million for Qantas and $11 million for Virgin Australia
Management:• The ONEMI put Chile on “red alert• Evacuees were moved into temporary shelters but by
the 19th of June the ONEMI decided that all 4,200 evacuees could return home, as the scale of the eruption continued to decrease
• The Argentinian government supplied $2.41 billion dollars to 1,400 farmers and businesses in the area affected and planned to spend $7 million on the cleanup operation
• 3,500 people were evacuated
Nevado del Ruiz, Colombia (5) Social:• Lahars killed 18,000 people in the town of Chinchina and 22,000 people in
Armero (nearly 70% of the population of Armero)• Most of the housing was destroyed and 8000 people were made homeless
Economical:• Livestock and crops were destroyed - over 3400 hectares of agricultural land was
lost• 60% of the regions livestock and 30% of sorghum’s rice crops were destroyed• Most roads, bridges, telephone lines and power supplies were destroyed and the
whole region was isolated• The cost of the eruption to the economy of Colombia was estimated at US$7.7
billion (about 20% of GDP that year
Management:• The hazards had already been mapped by scientists who had started gathering
data since early 1985 and the hazard map was due to be presented the day after the disaster
• In 1986 scienetists said people could return home however two days later there was a mud flow in Armero
•
World Cities and Urbanisation
Examples of Types of Cities• Megacities: Delhi(India),Dhaka(Bangladesh),
Lagos(Nigeria)• Metacities: Tokyo(Japan)World Cities:London(England),Chicago(America)
Mumbai: Back ground Problems:• 14,350,000 population• Indian Financial Centre and the centre of
Bollywood• Population due to read 26 million by 2025
Growth problems facing Mumbai• New migrants are coming in everyday wanting a
share of the new wealth• The port has enable India to become a exporter• Most of the migrants are uneducated and
therefore are not needed in a modern city• It has caused urban sprawl (cheap and poorly
built)• Massive overcrowding• Development of squatter settlements like
Dharavi• The Mumbai Suburban Railway, created in 1853,
links Mumbai to rest of India which is good for business and trade making it the best way of transport in Mumbai (7million/year). Means more people are being able to come to the area causing a shortage in houses.
Dharavi: • It is the biggest slum in Asia• Home to more than 600,000 people spread
over 175 hectares
Economical:• Industries are estimated to make
$700million dollars worth per year• There are 4,500 industrial units in Dharavi
producing leather,clothes,jewellry,food and soap
• Huge recycling industry employing 250,000 people
• Less than 10% is legal buisiness
Problems:• Dharavi restricts the growth of Mumbai• Dharavi sits south of the Mithi River not far
from Bandra Kurla Complex>Major buisiness hub
• Huge hubs or typhoid and cholera
Mumbai continued: SRA Development: • The slum dwellers whose names was
on the voters list of 1995 will be eligible for rehabilitation
• Each family will be allotted 225 square foot free of cost
• The residents will have to pay for their own water and electricity
• They gain wider roads,electricity,ample water,medical centres,and playgrounds/schools
• Dharavi will be divided into 10 sectors a developer responsible for each one
• Buildings will be 7 storeys high• The non polluting businesses in
Dharavi will be kept they will also be provided with modern technology
2004 Dharavi plan: • 1 million low cost homes will be built• Slum populations will fall to 10-12%
instead of 60%• There will be 325 open green spaces• 300 public toilets• The land that Dharavi is built on is
worth $10 billion dollars as it has a prime location
• For every sqft of new affordable housing built the developers will be allowed 30% commercial development e.g for shops
• By 2013 it is supposed to be a world class location
Examples of city areas• 1960-1981 1.6 million jobs were lost from
the inner city areas• 1994 the inner cites had an unemployment
rate of 50% higher than the rest of the country
• New Town>>Telford (west midlands)• Expanded Towns>>Bromsgrove and
Droitwich
Suburbanisation: (7)Why people moved:• Home to TV and film industry, so workers have
higher paid jobs• Higher disposable incomes means that car
ownership increases so commute to work• Other services locate here as people can afford
to use the service• Higher incomes means people want larger
houses with gardens and garages for family• Increased I.T technology allows people to work
from home• Only 7.8% in Beverly Hills do not own cars• Certain races forced out due to migration of
another race causes suburbanisation• E.g. Compton is a poorer district where 28% do
not own cars, populated with Hispanics. • When the Hispanic people moved into
Compton, the previous race, of white ethnic background moved out. Causes LA to spread further out = Urban sprawl
•
• Case Study: Los Angeles, USA:• Located south California, West USA• 3.8 million people in 2006• Young unskilled workers attracted to the
area due to Hollywood and Beverly Hills, film and TV industry
• Effects: the movement of people and excessive amounts of suburbanisation causes urban sprawl.
• Problems:• More congestion of cars travelling inner city• Pollution :air, noise, visual• Higher crime rates in poorer districts e.g.
Compton• Shortage of houses• Urban sprawl, loss of rural areas, country
side and villages. Social segregation, all wealthy in suburbs and poor are trapped.
Suburbanisation facts• In 2008 it was the plan to build 490,000 new
homes in the west midlandsLongbridge (brownfield) (4)• Birmingham City Council and Bromsgrove
District Council• a regional transportation interchange with
1,000 park and ride spaces, and the creation of at least 10,000 jobs.
• Birmingham CC lead on the project, and Worcestershire CC and Bromsgrove DC have been involved
• Huge plot - 468 acres• £1 billion Longbridge scheme is one of the
largest regeneration projects in the West Midlands
• 2,000 new homes
Brecon View housing – Gornal (greenfield):• There are four primary schools
and four secondary schools located nearby
• Sainsbury's Supermarket less than a mile away but Dudley town centre, located less than two miles away, has high street stores and boutiques.
• Tandon, Greens and Lower Gornal Medical Centres close by
Case Study: Notting Hill Gentrification London borough of Kensington and ChelseaWest London• During the Victorian times the area was rough and full of working class people• In the 1950’s it became a slum area of inner city deprivation• 1958 was the race riots between Afro Caribbean and the ‘Teddy Boys’ • 1959 The Notting Hill Carnival was started by Claudia Jones as a response to the riots and the state
of race relations in Britain at the time.• Area is famous for Portobello market and carnival What?• Past 30 years it undergone gentrification e.g. primrose Hill • Property prices have rose to £4million• Secluded communal gardens = more desirable for wealthy families with children • ‘Notting Hill’ movie helped popularise the area although gentrification had already happened• Now has 21 screen cinema opened in 2001• Many services such as boutiques, restaurants e.g. Feng sushi, wine bars etc.
Counter Urbanisation:Copmanthorpe: • Few km south west of York• Become commuter villages• The A64 provides a fast link between York and LeedsImpacts:• The population increased from 1,261 (1961)-4,008(1991)• 50% of the population have two or more cars• And 32% of the population is between 35-65• Gained a hair dressers, cooperative, and a fish and chip shop• Also has an improved toddler play group
Bayston Hill (48km from Shrewsbury): • Has a population of 5,500 in 2007• In 1971 1520 new homes were built• Before 1971 the population was 2000 it grew to
5345• The Meole Brace retail park was built in the
1980s to attract new shoppers• 97% of people still use local shops
Swardeston (7km south west of Norwich) • Has commuter services into Norwich(buses
and park and ride)• Many of the new homes are very expensive
7/9 of the houses are above the UK average of 168,000
• The village shop closed down as a result of a Tesco extra opening 5km away

Global warming examples1. The UN estimate that average temperatures will rise by 3.5˚by 21002. Over 650,000 years CO2 levels have never reached 300 parts per
million3. More precipitation in fewer days>>37 inches of rain in 24 hours
Mumbai India 20054. Artic ice cap diminished by 40% in 40 years5. If Greenland melted it would raise the sea levels by 20ft6. Himalayas provides water for 40% of the world but if it melts there
will be major water shortages7. February 2000 the Japanese paid the government of New South
Wales in Australia £50 million to plant over 40,000 hectares of trees in 20 years
The African Savannah Statistics:• Savannah lands are likely to
experience and increase in temperature of 1.5˚by 2025

• Precipitation due to increase by 15% near the equator
• Precipitation may decrease by 10% to the north and south of the equator>>Horn of Africa
• During the rainy season 25-50% more rainfall expected
• A rise in sea level by 25cm is predicted by 2050
Climate:• The tropical wet/dry savannah climate
is experienced over a huge area of western Africa ,the rainforests and equator
• an increase of variable rainfall could lead to floods and droughts
• With more frequent droughts there could be an increase in desertification
• Coral reefs along the east coast of Africa may be lost
• Higher rainfall in the savannah lands near the equator may lead to an increase in trees
• Increased rate of evapotranspiration may result in lower annual discharge in rivers like Nile and Zambezi
International Protocols • 1992 Earth Summit in Rio de janero the
developed countries agreed to try and reduce emissions by 60%
• In 1997 in Kyoto (Japan) 100 governments signed a climate change protocol
After the protocol:• In July 2005 the G8 world leaders and
delegates from China,India,Brazil,south Africa and Mexico attended a conference in Glengles
• The G8 countries are home to 13.5% of the total world population and 39% of the greenhouses emission per year
• UN Climate Change convention in Bali was attended by 180 countries
• When the G8 leaders met in 2008 in Japan they promised to halve their greenhouse gases by 2050
The 1997 the protocol:• Most governments agreed that by
2010 they should reduce their emissions so they were less than they were 1990
• The USA produces 15% more co2 than it did at the start of the 20th century
• President Bush failed to carry out the protocol as he said it was flawed
• In 1996 the USA released 21% of the global co2 even though it has 4% of the world population
National ResponsesClimate Change Programme(2006): • Building regulations tightened so
more insulation• Vehicle exercise duty and company car
tax changed so finical benefits come with low carbon cars
• The Carbon Trust was granted £65million from the government to help get small energy efficient businesses off the ground
• In Scotland woodland creation schemes were sponsored as they were designed to reduce the amount of nitrous oxide
Climate Change Bill(2008): • By 2020 the country hopes to have 26%
reduction in CO2 emissions from the 1990 records
• By 2050 they hope to decrease it by 60%• An annual review of targets by the
independent committee on climate change
• The creation of 5 year carbon budgets which set binding limits on CO2 emissions
• Expansion of the renewable transport fuels operation which will increase the proportion of biofuels used in transport
• Assisting local authorities to improve their household waste reduction and recycling scheme
• The UK has not reached it’s current target but has managed to meet the protocol target!:P
The Great Storm: The depression began over the Bay of Biscay as a result of south westerly winds carrying warm,wet air from the North Atlantic met with north easterly winds carrying cold air from the pole1. The depression deepened rapidly as a result of warm sea surface
temperature and a steep temperature gradient of the two air masses
2. The Polar Front jet stream was located further south then normal so the depression formed over northern France and southern England
3. On the 15th October pressure in the centre of the storm reached 953 mb
4. The storm hit the south coast of Cornwall and Devon shortly after midnight and moved over the midlands and reached the Humber estuary at 5:30 am on the 16th of October
5. The depression began to weaken and moved over the North Sea
Impacts:Social:• 18 people died in England and 4 in
Northern France• 150,000 homes lost their telephone
connections• Several hundred thousand people
were without power for 24 hours
Economic :• Shanklin pier in the Isle of Wight was
destroyed• Insurance claims totalled £1.4 billion• Gatwick airport closed and thousands
of boats were wrecked
Environmental:• 15 million trees were blown down• Some areas lost 97% of their trees
affecting ecosystems
Responses and Management:• Phone companies and electricity boards
worked round the clock to resume normal service
• Highway agencies began to clear roads and railways
• Forestry workers collected fallen trees as 4 million m³ of timber needed to be recovered
• The Forestry Commission established the Forest Windblown Action Committee to help advise people on how to recover fallen trees
• The Met Office were criticised as severe weather warnings were only given 3 hours before the storm hit
• The government has now established a national severe weather warnings system
• There was no prior warning given to the CGB the current power suppliers at the time
• The UK only had 8 stations for aerial monitoring which was not enough
British Climate• March 2013 coldest march since records
began more than 3 degrees lower than average due to polar continental air
• December 2010 was 4 degrees below the average it was caused by very high pressure blocking mild westerly winds so we received artic air masses
Tropical Climate (West Africa)Climate:• There is a distinct wet season (May-September) which is a result of the Inter Tropical Convergence
Zone(ITCZ) moving northward• During the dry season (October- April) the overhead sun migrates south and the ITCZ rain belt moves with
it leaving Kano dry
Temperature:• Temperatures are generally high and fluctuate slightly due to the fact that the sun remains high in the sky
most of the year round• During December temperatures do dip slightly as the sun is at a lower angle• Cloud covering from the wet season can reduce the temperature and is blocks incoming radiation• During the dry season the lack of cloud means that heat escapes during the night• The wet season brings a very small range in temperature
Precipitation:• During the wet season rain falls as heavy showers with thunder• Huge downpours are caused by high temperatures causing air to rise and meet the low pressure of the
ITCZ
Winds:• During the Dry season strong winds blows from the North knows as the west African trade wind or the
Harmattan• The Harmattan brings dusty conditions to Northern Nigeria as it has travelled over a lot of desert regions
FINISHED!!!!!!!!!!!!!!!!!!!!!!!Have fun-_-
