2
Q
What is GPS technology?
A
monitoring from space recording changes in temperature shows when magma is close to the surface
3
Q
What is gas sampling?
A
monitoring changes in gas composition which indicate the level of activity going on underground
4
Q
What is geothermal monitoring?
A
monitoring the bulging of the volcano as magma approaches the surface
5
Q
What is seismic monitoring?
A
listening to rising magma as it forces it’s way to the surface creating small earthquakes
6
Q
What is history of eruptions?
A
looking at the history of eruptions to find patterns and predict when the next eruption will be
