[MTT39-01] Infrasound from natural phenomena observed by infrasound observation network for study on early detection of tsunami
Keywords:Infrasound, Tsunami, Volcanic eruption, Bolide, Microbarograph
Since a variety of phenomena can excite infrasound as well as large scale sea-level change, such infrasonic signals are frequently observed at the infrasound observation sites mentioned above. In this presentation, we will introduce some cases of detected signals traveling from known sources such as a volcanic eruption, a bolide and so on. Through the analysis on observed signals from a variety of phenomena, it is expected to accumulate useful information for application to source identification and propagation characteristics of signals.
