How can tectonic hazards be managed? Volcanoes Connector 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 For sale! Three bedroom detached house in a lovely area Lots of jobs nearby and fantastic views of a framing countryside Eco friendly heating Why do people live near volcanoes? Discuss in pairs Write idea on the white boards Ask another person to explain what they have written Answers Jobs due to tourism Fertile soil Geothermal energy Jobs through mining minerals 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? 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? 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. (Can you identify the mistakes?) 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? Page 16/17 Prediction Preparedness Look at the exam questions. Choose two to answer now 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.
