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)

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.

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

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)
