These waves have the potential to provide constraints on the conduit geometry of a volcano. However, to further investigate the waves scientifically, such as how the conduit shape modulates the waveforms, we still need to examine many more examples. In this paper, we provide the most detailed descriptions of.The rotary subwoofer is a novel low frequency transducer capable of efficiently generating infrasound from a compact source. A field-deployable version of this device may find application as a calibration source for infrasound arrays of the International Monitoring System (IMS) ((2001).

Figure 2 shows infrasound feature vectors of three different classes: earthquake, tsunami, and volcano. They were obtained using the method described previously. These results show that there is a high degree of similarity among the feature vectors in each class, while there are clear differences between classes. These features may be helpful for classification and may improve the accuracy of.Read More
We review recent advances in the field of volcano acoustics with an emphasis on scientific and potential civil application gains from the International Monitoring System (IMS) infrasound network.Read More
Volcano infrasound recordings can be combined with seismic monitoring to help illuminate whether or not material is actually coming out of the volcano, therefore posing a potential threat to society. This presentation aims to summarize results from many recent studies on acoustic source inversions for volcanoes, including a recent study by Iezzi et al. (in review) at Yasur volcano, Vanuatu.Read More
A two-day volcano acoustics workshop was held at Sakurajima (Japan) in conjunction with the IAVCEI July 2013 general assembly.

Volcano infrasound merits particular attention when it changes over time. This can happen when volcanoes change their shape as crater walls slump, floors collapse, or a lava lake rises and falls.Read More
Since 1990, the Laboratory of Experimental Geophysics infrasound has applied to the study of volcanic explosions, especially on the Stromboli volcano (ME), and then widen the scope of investigation to mining activities in the quarry, and more recently to the study of gravity waves to the study of the atmosphere and the identification and study of avalanches and pyroclastic flows.Read More
