Learning Goals
Methods & Goals of the Course
1) Field & Lab examination of volcanic rocks and deposits
- Goal: To learn to observe, describe, & interpret volcanic deposits in a scientific manner
2) Review and explore the physical properties of magmas
- Goal: To gain an intuition for how magma properties vary and how these properties relate to eruption characteristics/style
3) Characterization of "eruption style"
- Goal:To understand the range of volcanic activity and the reasons for different behaviours
4) Study the linkages between eruption style and deposit characteristics
- Goal: To understand the range of volcanic activity and the reasons for differrent behaviours
5) Volcanic Hazards
- Goal: Identification of volcanic hazards, assessment of risk, mitigation strategies.
