- Predicting Volcanoes
- Use GPS technology to check for bulging magma in volcanoes - tiltmeter
- Gas sampling - Changes in gas composition indicates activity below - spectrometer
- Geothermal monitoring from space
- Seismic monitoring - small earthquakes sometimes happen before volcanoes errupt
- Looking at past eruptions to see if there is a pattern
- Water levels and water temperature can change
- Predicting Earthquakes
- Water levels can rise in wells and lakes - liquifaction
- Rise in electrical discharge
- History of earthquakes - pattern
- Forshocks before the main quake detected by a seismeter
- Use satalites to detect movement
- GPS in bous for tsunamis
- Laser beams in crust along fault line to detect movement
- Animals can act strangely
- A tiltmeter can check movement in rocks
