Swap the information you collected for homework.
Finish the sentence……….
The impact of earthquakes is far greater on LEDC. In Sichuan
in 2008 ……………………….
Remember to use comparative phrases when comparing two
places/events
By the end of the lesson:
 All pupils will be able to explain why people live near
Volcanoes
 All pupils will develop a case study of a Volcanic event
in an LEDC country
 All pupils will be able to identify short/long term
management plans when a tectonic disaster takes
place
 All pupils will be able to answer an exam question

Mount Nyiragongo
An eruption took place in January 2002.
What questions do you need to ask to develop this as a
cases study?
Look at the information provided.
Can you see any answers to the questions you have asked?

Look at the information provided.
Can you see any answers to the questions you have
asked?
Can you put the information into
the correct column
Now fill in the social, economic and environmental impact
Now you have the information can you answer the
following exam question
Using an example, describe the effects a volcano has on
people and property (4)
 Using an example, describe the effects a volcano has
on people and property (4)
In Congo, africa Mount N erupted as it’s on a conserative
boundary the lava is a very runny basalt which meant
that people were unable to flee the area in time and
therfire perished. Due to the high temperature of the
lava and the woden material of the houses a lot of
homes burnt down leaving people homeless.

What happened once the Volcano
erupted?
Put the last pieces of information in.
Looking at the aid that was given, do you think the relief
effort was successful?
Discuss
Mount Nyriagongo was affect again on 2005
Gases like carbon dioxide and sulfur dioxide rise through
Lake Kivu . An earthquake could shake these gases
free. In Lake Nyos in Cameroon 1700 people
suffocated from breathing in too much carbon dioxide.
What needs to happen in the long term?
Mitigation
These measures are put in place to reduce both the effect
of the hazard and the vulnerability in order to reduce
the scale of a disaster.
Preparedness
This means that Governments, communities and
individuals are ready to respond rapidly when a
disaster strikes and cope with the situation effectively.
Mount Nyiragongo
Within days, people began to return to Goma.
This was a crisis !
Why?
What could be done to minimize the death toll and
damage to Goma?
Discuss in pairs
What do you do?
Evacuate procedures
Lava bomb shelters
Aircraft to monitor the amount of gas released
Tiltmeters to detect when volcano swells up with magma
Boreholes to measure temperature
Seismometers
Lahar channels to divert mudflows
Evacuation routes clearly signed
Concrete shelters
Warning systems
Put these into prediction and
preparation methods
Which methods do you not understand?

Using examples, explain how Volcanic eruptions can be
predicted. (4)
Suggest two reason why the number of deaths varies
between earthquakes (4)
Describe one way a region affected by Volcanoes can
prepare for this hazard (4)
For either an earthquake or a volcanic eruption you have
studied, describe the immediate responses in
managing the impacts (4)
Mark each others work
Put a tick where you think they have got a mark
If they do not get 4 out of 4, what did they need to do to
get full marks.
