Description:
The Indonesian island of Sumatra, located in one of the most active zones
of the Pacific Ring of Fire, is characterized by a chain of subduction-zone
volcanoes which extend the entire length of the island. As a group of volcanic
geochemists, we embarked upon a five-week sampling expedition to these
exotic, remote, and in part explosive volcanoes (SAGE 2010; Sumatran Arc
Geochemical Expedition). We set out to collect rock and gas samples from
17 volcanic centres from the Sumatran segment of the Sunda arc system,
with the aim of obtaining a regionally significant sample set that will allow
quantification of the respective roles of mantle versus crustal sources to
magma genesis along the strike of the arc. Here we document our geological
journey through Sumatra’s unpredictable terrain, including the many
challenges faced when working on active volcanoes in pristine tropical climes.
