Mapping the types of deposits
is an important part of volcanology, especially for
those volcanoes whose activity has not yet been
observed by humans. Though analysis of
volcanic deposits is by no means flawless, it can
give clues about what future eruptions may look
like, as well as aid in the assessment of the risks
and hazards associated with any given volcano.
