Magma balloons or bombs?

To the Editor

Detailed analysis of volcanic materials1 allows the study of eruptions that have not been witnessed directly. Rotella et al.2 undertake the challenge of interpreting submarine volcaniclastic deposits around Macauley Volcano, part of the Kermadec Arc in the southwest Pacific Ocean. They propose a 'Tangaroan' eruption style, based on the textural characteristics of dredged pumice clasts. However, we argue that the analytical methodology provides an inadequate basis for the identification of a new eruption style.
