Because sources of volcano infrasound are shallow or aerial, infrasound observations can provide valuable information on eruption dynamics (Fee and Matoza, 2013). In addition to extracting eruption source parameters, higher precision source localization becomes feasible for volcano infrasound, because characteristic wavelengths of volcano infrasound are short (34–340 m for 10–1 Hz sound) compared with associated seismic wavelengths. Such high‐resolution source location makes it possible to differentiate active vents in a multivent system (Ripepe et al., 2007; Jones et al., 2008; Johnson et al., 2013) and to track surface flow phenomena such...
