Tropical Storms

There are three steps that people are urged to follow to reduce the damage from tropical storms:                                           
  FORECAST - PREPARE - ACT

Forecast

  • Rich MEDCs, such as the USA, can invest in technology to predict the general area in which hurricanes will strike. This technology is not so readily available to LEDCs, although many countries receive information from organisations such as the Joint Typhoon Warning Centre (Pacific) or National Hurricane Centre (Atlantic) to help them prepare for storms.
  • The track of a tropical storm is affected by a great many factors, so they are very unpredictable. Forecasters have a 20-25% chance of knowing exactly where a tropical storm will hit 48 in advance of landfall.
  • Forecasts are made available to residents on the internet so that they can make decisions about whether they need to evacuate. This is obviously a much more useful means of communication in an MEDC where the percentage of residents with internet access is much higher than in LEDCs. Indeed, one of the major problems in preparing for a strike in an LEDC is communicating with the people in an area that is likely to be affected as the infrastructure may well be poorly developed.

 

 Prepare

Most countries affected by tropical storms now have education programmes to raise awareness on preparing for storms. There is an annual Hurricane Preparedness Week in the USA when schools, businesses and families are all encouraged to plan for possible strikes in the forthcoming hurricane season. Leaflets, posters and school lessons are common ways of spreading the message. New technologies - such as Twitter are also being used to educate people.

People living in areas affected by tropical storms are encouraged to have a hurricane emergency kit on standby and also to have thought in advance about how they will protect their home and belongings. This might include boarding up windows and doors. In MEDCS, people may also be able to afford windproof tiles, water-resistant windows and strengthened building structures.         

People in LEDCs may not be able to afford this kind of protection. However, simple but cheap measures can be put in place to ensure that people are well prepared for tropical storms. These include educating people (particularly women) about what to wear in case they have to swim, building homes on stilts, building cyclone shelters and training local people to organise others in an evacuation.

 

Act

  • When landfall has been forecast, action needs to be taken. This might include boarding up windows and doors, or evacuating the area.
  •  A mandatory evacuation is where the authorities command everyone in an area to leave. It is vital to ensure that only those people who are in the danger area try to leave - otherwise the road system will get clogged up and people will be put at greater risk.

Volcanoes


How can people plan and prepare for a volcanic eruption?

 

If an eruption is predicted, access to the volcano may be restricted or the area might be evacuated (i.e. people moved away to a place of safety). We  looked at the example of Chances Peak in Montserrat - the island is zoned into evacuation 'no-go' zones and areas where people can stay but need to be ready to leave quickly. When the volcano started erupting in 1995, access to the south of the island was restricted and around 5000 people were evacuated to the northern part of the island where a new port area was built at Little Bay to allow people to leave the island. The volcano is still erupting, and the island zone map and hazard level classification system is shown below.

 
 

When lava flows are threatening a town or village, it may be worth the expense of building earth or rock walls to divert lava flow or even using planes and helicopters to drop water to cool the lava and slow it down. This happened in Iceland in 1983. The military might be called in to use bombs and dynamite to alter the flow of the lava (these techniques have been used by the Italian authorities when managing Mount Etna).

 

In areas where volcanoes give out large amounts of ash, building design can help to limit the damage caused by an eruption. Flat-roofs are a major risk as ash settles on them and becomes very heavy, causing collapse. Sloping roofs are much better, particularly if they can be made from smooth materials such as metal and glass which are more likely to shed the volcanic ash. People living in affected areas should also make sure that doors and windows have a good seal and that filter systems are installed to limit ash damage to computer and electrical systems.

 

Residents should keep an emergency kit - water, tinned food, wind-up radio, tape, towels, googles, torch, breathing mask - in case the volcano erupts. Campaigns in areas subject to eruptions have helped to educate people about the importance of keeping an eruption kit. In some areas, practice drills are held to make sure that everyone knows what to do in an eruption. Evacuation routes can be planned and tested, and signposts can help to inform people of escape routes. Volcanic hazard maps can also be used to help predict the likely consequences of an eruption.

Year 10 Hurricane Case Study. Study the following links. What are the key differences between reponses to hurricanes in a LEDC and a MEDC?

Case Study on Hurricane Katrina 2005

Case Study on Hurricane Nargis 2008

What can be done to reduce the impacts of Volcanoes?
 

Prediction
Technological advances are making it easier to predict volcanic eruptions.
  • Satellites monitor the temperature and shape of active volcanoes.
  • Sensors measure levels of sulphur dioxide and carbon dioxide gas
  • Seismometers record earthquakes as magma rises to fill the volcano
  • Tilt meters record any change in the shape of the volcano
  • Volcanoes can be studied similar to an organ pipe and for the increase in pressure prior to an eruption
Preparation
Being able to predict volcanic eruptions makes it easier to prepare for them
  • Hazard maps are drawn up to show areas at risk
  • People are evacuated to safe areas.
  • Lava flows may be diverted by spraying them with water, or even bombing them
  • Emergency services can be trained to be ready for an eruption and deal with injuries etc
  • Emergency supplies can be got ready such as food, water etc
  • Provide an after eruption plan to return the area to normal with plans for clearing up the mess and repairing the damage.

Can you guess what it is? Where it is?

Question: What is the difference between a spit and a bar?

Answer: A bar develops by the process of Longshore drift,which occurs due to waves meeting at the beach at an angle and backwashing perpendicular to the shore, moving sediment down the beach on a zigzag pattern whereas, a spit is a deposition landform found off coasts. At one end, spits connect to land and extend into the sea.

What are the advantages of living in earthquake zones and areas close to volcanoes?



Geothermal energy

Geothermal energy is where steam from water heated by hot rocks below the surface of the earth is used to drive turbines and generate electricity. This is a very cheap and sustainable way of producing electricity since it uses a renewable source. More than 70% of the homes in Iceland are heated by geothrmal energy.



Tourism

Volcanic landscapes often have very beautiful scenery. They attract a whole range of visitors from students on geography fieldtrips to artists, photographers, walkers etc. Tourists migh come to watch eruptions, see geysers, relax in hot springs or have mud baths (we hope to do all of these things on the GCE Geography fieldtrip to Iceland!). The tourism industry that builds up in the area can provide many jobs and these encourage people to live in the area. Thse include jobs as gudies, in visitor centres, in hotels and other types of accommodation as well as in gift shops, cafes. bars etc.



Fertile soils



The volcanic rocks are very rich in minerals. They form fertile soils when weathered, and these are ideal for growing crops. On Mount Etna in Sicily, yields of grapes are five times higher than the national average because the soils are so fertile.



Raw materials and minerals

Many valuable minerals are erupted from volcanoes and these can be collected and used. Gold, silver, copper and tin are found in the remains of extinct volcanoes. In active areas, heated groundwater concentrates traces of these minerals into rich veins which can then be mined. 


   

Why do people still live in danger zones?

Many people choose to live in these areas because of the benefits listed above but a great deal of others stay because they unable to relocate away from the danger zones. For many people, the advantages of living in a danger zone by far outweigh the risk of coping with the possibility of an earthquake or eruption. Make sure you know the reasons listed below as well as the benefits listed above!

- some people think that disasters only affect other people and will never harm them - they ignore the dangers and assume they will be OK
- some people come from families who have lived in danger areas for many many years - long before they knew that they were hazard zones - and they don't want to break family ties by moving away
- some people think that scientists will be able to predict any seismic activity long enough in advance for the area to be evacuated - so they feel safe to live there
- some people simply may not be able to afford to move anywheere else
- some of the settlements in danger zones eg. Mexico ity, San Francisco, Los Angeles, have grown into enormous megacities and there just isn't space to rebuild them elsewhere away from danger


Friday

we are sitting unit 2

Tonight you could look at volcanoes ....


Composite volcanoes


  •  
  • Composite volcanoes happen where the lava is acidic. 
  • The sticky acidic lava pours slowly down the side of the cone and cools quickly to produce a steep sided volcano. 
  • Alternate layers are formed because each eruption first produces rock fragments which are later covered by lava
  • This kind of volcano is found at destructive plate margins.







Shield (basic) volcanoes




  • Shield volcanoes are enormous features built up only from layers of lava
  • They produce lots of lava but they tend not to erupt violently. Shield volcanoes form when the lava is basic (the opposite to acidic). 
  • You get these types of volcanoes along constructive plate margins and also where there are hotspots. Basic lava is runny so it flows quite a long way before it cools.













The effects of volcanic eruptions

The effects of volcanic eruptions can be divided into primary and secondary effects
The primary effects are immediate and come from the eruption itself whereas the secondary effects result from the primary effects. 


 
  
Primary effects of a volcanic eruption
  
You need to learn the definitions of the terms volcanic gases; lava flows; pyroclastic flows; tephra.
  
  • Volcanic gases - All magma contains dissolved gases that are release during and between eruptions. These gases are mainly steam, carbon dioxide and compounds of sulphur and chlorine.
  • Lava flows - These are streams of molten rock.
  • Pyroclastic flows - These are high speed avalanches of hot ash, rock fragments and gas which move down the sides of a volcano. These flows occur when the vent area or ash column collapses.



Secondary effects of a volcanic eruption

Make sure that you know at least 3 secondary effects of an eruption in detail.

  • Lahars - These are mixtures of water, rock, ash, sand and mud that originate from the slopes of a volcano. Lahars often happen because of heavy rainfall eroding volcanic deposits or heat from a volcanic vent suddenly melting snow and ice.
  • Landslides - Heat from cooling magma can cause hydrothermal alteraton of the rocks, turning sections of them into clay. This weakens the rocks and increases the risk of slope failures.
  • Flooding - Explosive eruptions can change thge surface areas around a volcano and disrupt drainage patterns, leading to long-term flooding.

Other secondary effects include:

  • Food / water supply interrupted.
  • Homelessness.
  • Businesses forced to close.
  • Cost of insurance claims.
  • Unemployment.
  • Long-term issues with the tourism industry. 



Thursday


What is a tropical storm? How do they form?


  • Tropical cyclones use warm, moist air as fuel. That is why they form only over warm ocean waters near the equator. 
  • The warm, moist air over the ocean rises rapidly upward from near the surface and becomes saturated with evaporated moisture. This means that there is less air left at the surface (i.e. low pressure). 
  • Air from surrounding areas with higher air pressure pushes in to the low pressure area to try to equalise the pressure. 
  • Then that “new” air becomes warm and moist and rises, too.
  •  As the warm air continues to rise, the surrounding air swirls in to take its place. Trade winds cause the moist air to spin inwards. 
  • As the warmed, moist air rises and cools off, the water in the air forms towering cumulonimbus thunderclouds (because there is a huge amount of condensation). 
  • The whole system of clouds and wind spins and grows, fed by the ocean’s heat and water evaporating from the surface.

Revision after school tomo night - don't forget

Earthquakes ...

  • Earthquakes are usually caused when rock underground suddenly breaks along a fault. 
  • This sudden release of energy causes the seismic waves that make the ground shake. When two blocks of rock or two plates are rubbing against each other, they stick a little. 
  • They don't just slide smoothly; the rocks catch on each other. 
  • The rocks are still pushing against each other, but not moving. After a while, the rocks break because of all the pressure that's built up. 
  • When the rocks break, the earthquake occurs.
  •  During the earthquake and afterward, the plates or blocks of rock start moving, and they continue to move until they get stuck again.
  •  The spot underground where the rock breaks is called the focus of the earthquake. 
  • The place right above the focus (on top of the ground) is called the epicenter of the earthquake.


Monday

Have a look tonight at your case study on wildfires in California -make sure you know the effects below:

Effects
The fires forced approximately 1,000,000 people to evacuate their homes, the largest evacuation in California's history.
Over 1800 homes were destroyed.
Over 2,000 km² of land burned.
Nine people died as a direct result of the fires. 85 others were injured, including at least 61 firefighters.
Damage to property estimated at US$1.6 billion.
Air pollution levels raised across the area to 3 times their normal level - this causes breathing difficulties. People were advised to stay indoors.
Tourist trade was damaged. San Diego Zoo and Sea World were closed.
Drinking water in some cities was pollutd and people were advised to drink only bottled water.
Crops were destroyed, either by the fire itself or because they weren't watered as the farm workers had been evacuated. Food prices rose.
Many species of plants and animals were killed.

Well done today -excellent attitude and effort during our revision lessons - very impressed with your effort and attitude..

Tonight you could focus on case studies and command words - revisit everything we looked at today to really get the ideas stuck in your head...


Tuesday 17th Jan

Tonight you might like to focus revision on Conflicts - 

How can it be fair to spend £60 million on defending Sea Palling whilst Happisburgh is left to erode?

Have think about this question - look through your exercise book and see if you can design a spider diagram ( mind map) to highlight the key issues surrounding coastal conflicts - make sure that you include the following key words :

coastal blight     economic value     Sea Palling   Norfolk Broads (unique ecosystem)  thriving community     buy  a rock for Happisburgh  fastest eroding coast in Europe Shoreline management plan (SMP )   hold the line     do nothing 
revetments  10-15 meteres lost per year

few videos to watch :





Monday 

Wow 42 of you at revision! Fabulous turn out well done!
tonight I would focus on the coast as a multi use area - apart from Emily most of you did not seem to know the definition of a a multi use area .

Learn the definition and then try to learn five ways that Liverpool is a multi use area.

then try the 8 mark past question higher ( 6 marks foundation)

Describe and explain the reasons for the growth of populations in coastal regions.




Sunday

morning folks - just finished marking your mocks -you are all making the same silly mistakes - I would like you to focus today on command words - write these words out and get  a kindly parent to test you 

describe - this means say the characteristics of something for example describing the shape of a beach in your mock - is it wide, narrow made of sand , long, thin etc.

explain - this means say why something has happened - again in your mock this would be explain why a beach with groynes is wider than one without groynes. -so it would all be about sand getting trapped from process of log shore drift.

using your own knowledge - say something you know about from our lessons

using fig 4 ... make sure you say in your sentence "...  as figure 4 shows"

how - here you need to say how something is protected not why - what has actually been done

why  - here you need to say why in other words what are the reasons for something happening.

You need to be underlining these command words - no one is doing that it is crucial for success - there is no point writing loads of information that is not answering the question - PLEASE CHECK OVER THESE WORDS CAREFULLY

You all also need to have better knowledge on longterm planning - Ancona, and ICZM and  SMP
have good revising day

Friday - last weekend before the exam -try to use your time sensibly and build into your weekend some revision as well as some much needed lazy time..

tonight you could look at the formation of a wave cut platform and rockfalls - when the rocks fall down - it hasn't come up for a while:


  • wave cut platforms happen on hard coastlines
  • they occur at the base of a cliff
  • abrasion is the main process of erosion but weathering is important too
  • the rocks fall into the sea and are then used again to pound the cliff face

look at the diagram below and learn it !




make sure that you can recognise what a wave cut platform looks like on a photo:


( thanks to geobytesgcse for the photo)

Thursday - mock for my class friday ......  try to keep to time 1 minute 1 mark 

tonight I would recommend that you revise:

waves constructive and destructive
factors affecting the size of waves - fetch length of time wind blowing and duration of wind how long the wind has been blowing for
I would also probably revise soft engineering and longshore drift and probably cast my eye over caves arches and stacks


just some random ideas to think about tonight ........

Wednesday 9 days to go .....

How about a focus on the basics tonight ?

every question you are asked on the formation of a coastal erosion feature must include the processes of erosion.

Remember 

Erosion is... rocks being broken down and moved away. Marine erosion is the wearing away and removal of rocks by the action of the sea.

There are 3 processes of erosion :


Corrasion (abrasion) this is where the bits of rock and sand that are carried in the waves are hurled at cliffs and grind them down. It is sometimes described as sandblasting.

Attrition is where the waves cause rocks and pebbles that they are carrying to smash into each other and break down. They become smaller and rounder.


Hydraulic Action is the constant force of waves crashing on the shore. When waves crash against the cliffs they force air into cracks in the rock. The air is trapped, and pressure builds up. As the waves move back, pressure is released and the trapped air expands. Small explosions take place and weaken the rock, blasting fragments away.


Can you make up a revision nmenoic ( an easy way to remember the first letter of the word) I would have 
CAH  Harry always Cries

Weathering is the breaking down of rocks by the action of the weather, plants or chemical action. In happens in situ - this means 'without movement'. This is the main difference between weathering and erosion.


Weathering

Solution is where acids contained in sea water slowly dissolve certain types of rock. Sea water is very corrosive and slowly dissolves chalk and limestone. This increases the size of the cracks and joints in the rock so that the other forces of erosion can become more effective.



Wetting/drying is another form of weathering. Here, softer rocks like clay expand when they are wet and contract when they are dry (think about your pottery lessons if you need an easy way to remember this!). Over time, the continual expansion and contraction can weaken the rocks and make them more easily eroded by other processes.

Sub-aerial processes are processes that attack the face and top of a cliff - i.e. those parts that are exposed to the atmosphere. Sub-aerial processes include rainfall, surface runoff and freeze-thaw weathering.

bit harder to make a nmenonic for these letters - I made 
Wet and dry Sandwiches make me sick (rubbish - can you do better??)

Past questions have asked you to give a definition of erosion and weathering, explain the difference between the two - however you will most probably use the terms in your explanations as to how features such as wave cut platforms, caves arches  stacks  and rock falls occur.

Remember it is not enough to say that abrasion happens you have to say how abrasion works to get the full marks. ... Now learn the definitions  -easy marks night!!!! 



Tuesday

Hope English exam went well - now to focus on geography.
think you should revise tonight Shoreline Management Plans SMP


http://www.seftoncoast.org.uk/articles/99winter_shoreline.html

Use the link above to look at how SMPs are used to protect our coastline - use the menu on the left hand side and click on Crosby to Formby - has some interesting information on our stretch of coastline.
