... examined in detail. Sakurajima is well known for repeated Vulcanian explosions that produce high‐amplitude infrasound signals, providing an excellent volcano acoustic dataset. Sakurajima also provides an interesting opportunity, as the active crater is not at the summit of the volcano and vent‐station...

... Seismic and infrasound signals are produced by a wide variety of sources, including shallow earthquakes (e.g., Arrowsmith et al. , 2012 ), above‐ and below‐ground explosions (e.g., Jones et al. , 2015 ; Kim and Rodgers, 2016 ), volcanic eruptions (e.g., Lees et al. , 2008 ), and other natural...

...Steven J. Gibbons; Tormod Kværna; Svein Mykkeltveit All infrasound stations in the IMS are arrays, and necessarily so. The most important parameter associated with a seismic signal is its arrival time, and this attribute frequently can be obtained with great accuracy from a single‐site station...
