Scientists shine light on tiny crystals behind unexpected violent eruptions

In a new study of volcanic processes, scientists have demonstrated the role nanolites play in the creation of violent eruptions at otherwise 'calm' and predictable volcanoes. The study describes how nano-sized crystals (nanolites), 10,000 times smaller than the width of a human hair, can have a significant impact of the viscosity of erupting magma, resulting in previously unexplained and explosive eruptions.
