What are the processes that drive volcanic eruptions?
How do volcanoes change their eruptive personalities through time?
Currently we are focused on the relationship between geochemistry and explosivity at Augustine Volcano, Alaska.
Current and Recent Work
Current and Recent Work
The BLAST lab uses a variety of techniques to investigate volcanic eruptions. Current techniques include:
grain size analysis (using size data to infer the explosivity of previous eruptions) - how do different eruptions compare, and how does explosivity vary within a single eruption?
whole rock geochemistry (by XRF and ICP-MS)- how do tephra compositions vary between eruptions and within a single eruption?
