This is because they have been active in recent years and people who live nearby will benefit from warning signs if an eruption was to happen. However, as well as prediction, people need to be prepared for an eruption. ]]> 2016-08-31 16:07:30 UTC https://padlet.com/christine_heineke/7sk4f5beat/wish/120872897 The Technology christine_heineke https://padlet.com/christine_heineke/7sk4f5beat/wish/120874481 -Thermal imaging techniques and satellite cameras are used to detect heat around a volcano. The temperature increases as active inside it increases. 
-Gas samples can be taken and chemical sensors are used to measure sulfur levels. They do this because when a volcano is close to erupting gases are released. The more sulphur there is in it, the closer it is to erupting.
-A seismometer measures and records details of earthquakes, such as force and duration. They pick up vibrations made in the crust. ]]> 2016-08-31 16:11:32 UTC https://padlet.com/christine_heineke/7sk4f5beat/wish/120874481 Mount St. Helens erupting christine_heineke https://padlet.com/christine_heineke/7sk4f5beat/wish/120876905 2016-08-31 16:18:46 UTC https://padlet.com/christine_heineke/7sk4f5beat/wish/120876905 How they happen: christine_heineke https://padlet.com/christine_heineke/7sk4f5beat/wish/121057521 Volcanoes occur where tectonic plates meet and the Earth's crust becomes unstable. Volcanic eruptions happen at the boundaries between plates. Magma is less dense the the crust so it can rise to the surface through weaknesses in the crust, this forms a volcano. ]]> 2016-09-01 12:31:23 UTC https://padlet.com/christine_heineke/7sk4f5beat/wish/121057521 Fact! christine_heineke https://padlet.com/christine_heineke/7sk4f5beat/wish/121058602 Some eruptions produce runny lava while others produce thick lava that escapes violently. ]]> 2016-09-01 12:36:20 UTC https://padlet.com/christine_heineke/7sk4f5beat/wish/121058602 Fact! christine_heineke https://padlet.com/christine_heineke/7sk4f5beat/wish/121060022 Even though volcanoes can be destructive some people choose to live near them because volcanic soil if very fertile. It contains minerals needed for plants to have a healthy growth. ]]> 2016-09-01 12:42:00 UTC https://padlet.com/christine_heineke/7sk4f5beat/wish/121060022 Volcanic Plate Boundaries christine_heineke https://padlet.com/christine_heineke/7sk4f5beat/wish/121273689 2016-09-02 08:04:58 UTC https://padlet.com/christine_heineke/7sk4f5beat/wish/121273689 christine_heineke https://padlet.com/christine_heineke/7sk4f5beat/wish/121273798 2016-09-02 08:06:04 UTC https://padlet.com/christine_heineke/7sk4f5beat/wish/121273798 Seismometer: christine_heineke https://padlet.com/christine_heineke/7sk4f5beat/wish/121274035 2016-09-02 08:08:43 UTC https://padlet.com/christine_heineke/7sk4f5beat/wish/121274035 Preparing for an eruption: christine_heineke https://padlet.com/christine_heineke/7sk4f5beat/wish/121274222 The government needs to have a plan if a volcano could erupt in their area. This plan is there to reduce loss of life and cause as least damage as possible. The plan should include:
-Being ready to evacuate all residents in the area.
-Creating an exclusive zone around the volcano.
-A good communication system needs to be in place so people can communicate.
-Having an emergency supply of basic provisions such as food, water and somewhere to stay if home is lost. 
-Money needs to be saved to help the people affected.
