43. VOLCANO ERUPTION PREDICTION: 1.Volcanologists need to use scientific information to accurately predict eruptions. 2.Communicate information effectively to government and local officials. 3.Eruption predictions will help save life and property.

44. HOW DO GEOLOGISTS PREDICT ERUPTIONS? 1. Doming and Tilting:

45. HOW DO GEOLOGISTS PREDICT ERUPTIONS? 2. Seismicity: Changes in the number of earthquakes. 3. Changes in gas emissions: Example – There is an increase in the amount of hydrogen gas emitted before Kileaua erupts. 4. Periodicity: Cycles of eruptions

46. What can we do with predictions?  Hazard Maps  Evacuations
