Volcanic eruptions can have a devastating effect on people and the environment.
However, unlike earthquakes, volcanoes can also have a positive impact on an area. These positive impacts can help to explain why people choose to live near volcanoes.
|The dramatic scenery created by volcanic eruptions attracts tourists. This brings income to an area.||Many lives can be lost as a result of a volcanic eruption.|
|The lava and ash deposited during an eruption breaks down to provide valuable nutrients for the soil. This creates very fertile soil which is good for agriculture||If the ash and mud from a volcanic eruption mix with rain water or melting snow, fast moving mudflows are created. These flows are called lahars.|
|The high level of heat and activity inside the Earth, close to a volcano, can provide opportunities for generating geothermal energy.||Lava flows and lahars can destroy settlements and clear areas of woodland or agriculture.|
|Human and natural landscapes can be destroyed and changed forever.|
