Great diversity has been observed in volcanic infrasound signals worldwide, reflecting rich variability in their physical source mechanisms. Infrasound waveforms, estimated signal powers, and frequency contents vary dramatically across a large spectrum of physical eruptive styles (e.g., Johnson and Ripepe, 2011; Fee and Matoza, 2013; Garces et al., 2013). The observed infrasound signals and eruptive styles span, but do not fall neatly into, the idealized terms such as Hawaiian, Strombolian, Vulcanian, sub‐Plinian, and Plinian (e.g., Walker, 1973; Fee and Matoza, 2013). In physical volcanology, the description and classification of explosive eruption styles are traditionally...
