Transcript of Predicting and Preparing for Volcanic Eruptions

Worksheet
temperatures around the volcano rise as activity increases
Heimay
Describe and explain using named examples how volcanic eruptions are predicted and prepared for
Predicting Volcanic Eruptions
how can we predict volcanic eruptions?

note down as many different ways as you can think of
2 minutes
Predicting and Preparing for Volcanic Hazards
Mt Ontake
Japan
27th September 2014
take notes on the various different methods of predicting volcanic eruptions
When a volcano is close to erupting it starts to release gases. The higher the sulfur content of these gases, the closer the volcano is to erupting.
Seismometers are used to detect earthquakes.
Thermal imaging techniques and satellite cameras can be used to detect heat around a volcano.
Gas samples may be taken and chemical sensors used to measure sulfur levels.
