Question

Describe four methods that scientists use to predict volcanic eruptions.

Answer 1

seismometers - used to measure earthquakes occurring near an eruption

tiltmeters and GPS satellites – these devices monitor any changes in landscape. Volcanoes tend to swell near an eruption

monitoring gases escaping from a volcano using robots called Spiders – often there is an increased release of sulphur dioxide near an eruption

measuring temperature - volcanoes become hotter when magma starts to rise through the main vent

looking at the past history of eruptions - scientists can identify patterns of activity

Answer 2

Sorry mate i don't know the answer
