2. Imagine that you live in an area where volcanic eruptions occur. Draw up a list of emergency measures that should be applied before, during and after a volcanic eruption.
3. Collect newspaper articles on any recent volcanic eruption. Discuss it in class and name the consequences thereof.
4. What kind of aid was offered to these people by the rest of the world? Could more have been done?
an interesting fact
The enormous power that exists within the earth is frightening when you think of the death and destruction that is caused when it is revealed.
But it may be possible to think of it in a positive way: We can strive to learn to harness this power to make life on earth more comfortable. Perhaps ways of taming such power and applying it to produce electricity may be found. Think of the impact that such a source of energy will have!
A website like the following has interesting information about volcanoes in store:
| Learning Outcomes(LOs) |
| LO 2 |
| GEOGRAPHICAL KNOWLEDGE AND UNDERSTANDINGThe learner will be able to demonstrate geographical and environmental knowledge and understanding. |
| Assessment standards(ASe) |
| We know this when the learner: |
| 2.1 describes and explains how natural hazards such as volcanoes, earthquakes and flooding occur, and their impact on human lives and socio-economic activities [people and places];2.2 investigates and explains why some people face a higher risk than others with respect to natural hazards [people and resources];2.3 identifies how risks and hazards can be managed [people and the environment]. |
Activity:
2. Trace the world map in Figure 4 and indicate the zones where earthquakes occur, in red.
3. Yes, they occur in the same areas where there are volcanoes.
Earthquakes and volcanoes go hand in hand and are found on the periphery of the plates of the earth’s crust – there where the plates move slowly to or from one another. These movements cause earthquakes and/or volcanic eruptions.
Activity 2:
1. a) People
b) The environment
Activity 3:
1. People make an actual decision to live close to a volcano.
Economic considerations such as the availability of jobs and financial prosperity are often more important than the potential danger of living close to a volcano.
2. a) Before a volcano erupts:
Volcanoes are monitored by seismographs and warnings are issued.
Areas should be vacated if early signs are observed.
People living in such areas must ensure that they always have emergency supplies at hand.
b) During a volcanic eruption:
People must leave the area immediately.
Always listen to news broadcasts to follow the course of events.
Wear gas masks as prevention against sulphurous gases.
c) After a volcanic eruption:
Cleaning up operations must take place in the area and relief funding must be supplied by first world countries.
3. Collect newspaper clippings on any recent volcanic eruption and discuss it in class.
4. First world countries supply financial aid after such a disaster.
They also dispatch emergency teams to help with clearing up operations, medical services and food supplies.
