Detecting Geyser Activity with Infrasound
We monitored geyser activity in the Lower Geyser Basin (LGB) of Yellowstone National Park with dual four-element microphone arrays separated by ~600 m. The arrays were independently used to identify incident coherent plane wave energy, then conjoint cross beam back-azimuths from the two arrays were used to precisely locate signal sources. During a week in August 2011 we located repeating infras...

متن کاملVolcanic eruptions observed with infrasound
[1] Infrasonic airwaves produced by active volcanoes provide valuable insight into the eruption dynamics. Because the infrasonic pressure field may be directly associated with the flux rate of gas released at a volcanic vent, infrasound also enhances the efficacy of volcanic hazard monitoring and continuous studies of conduit processes. Here we present new results from Erebus, Fuego, and Villar...
متن کاملGeyser model with real-time data collection
The physical model of geyser oscillations presents a challenge to experts, even under relatively simple and clear laboratory circumstances. Despite complex dynamics a qualitative analysis can be made based on video recording and real-time temperature and pressure measurements. The simple experiment with Geyser model is rich with several phenomena from the field of thermodynamics that are includ...
متن کاملA portable infrasound generator.
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). The Global Verification Regime and the International Monitoring System (CTBTO Preparatory Commission Vienna I...
