Development of an Infrasound Propagation Modeling Tool Kit

An overview of volcano infrasound: From hawaiian to plinian, local to global

“…Both models are part of the InfraMAP package (Gibson and Norris, 2002), developed and maintained by BBN Technologies. Fig.…”

Infrasonic observations of the June 2009 Sarychev Peak eruption, Kuril Islands: Implications for infrasonic monitoring of remote explosive volcanism

“…However, in the following sections we highlight some features of infrasonic propagation from SP. In addition to ray--tracing, we use an implementation of the frequency--domain Parabolic Equation (PE) method (Gibson and Norris, 2002) in order to investigate low--frequency effects, i.e., diffraction and scattering. In the following sections our modeling efforts are restricted to propagation between SP and IS44, the closest recording station.…”

“…We investigate the importance of diffraction and scattering on infrasonic propagation from SP to IS44 using the PE software InfraMap (Gibson and Norris, 2002). Diffraction arises simply from using a more complete description of the acoustic wavefield (i.e., the PE method vs. ray--tracing).…”

Acoustic analysis of shock production by very high-altitude meteors—I: infrasonic observations, dynamics and luminosity

“…Additionally, it becomes possible to test various upper wind/atmospheric models by comparing arrival times with the predicted residuals. The raytracing was performed using both the InfraMAP software (Gibson et al, 1999) and Supracenter (Edwards and Hildebrand, 2004) software, to delimit the source regions and geometry of the observed airwaves. In general, we found almost no difference in the predicted arrival times using these two different software tools-in what follows we show only the Supracenter solution, noting that the InfraMAP solutions are virtually identical.…”
