KurzbeschreibungThis course will discuss the processes occurring from magma generation to eruption, covering topics such as magma formation, storage, movement, evolution, ascent in conduit and eruption dynamics. The course will also discuss deposits, and will prepare students to take the volcanology field course. Finally, an introduction on volcanic hazards and volcano monitoring will be presented.
LernzielAfter completion of this course the students should have a good understanding of the dynamics of volcanic systems, from source to surface. The students should understand the main steps involved in generating volcanic activity on Earth, to interpret the depositional processes operating during volcanic eruptions. There will be an emphasis on interpreting volcanic deposits and the role they can play in understanding depositional processes. Students should also be able to discuss potential hazards related to a given volcanic phenomena.
InhaltDuring the course, the following topics are covered:
- Basics of physical volcanology
- Physical properties of magmas
- The role of volatiles in volcanic eruptions
- Fragmentation processes
- Explosive volcanism – dynamics and deposits
- Effusive volcanism – lava flows
- Monitoring techniques used at active volcanoes
- Volcanic hazards

Some of these modules are accompanied by exercises
SkriptPresentation slides will be handed out
LiteraturPapers from the literature will be provided
Voraussetzungen / BesonderesSome previous courses in igneous / hard rock geology would be helpful.
