What is the wavelength (in seconds) of an eruption? What's the Nyquist sampling rate? Is there dispersion of audio signals in the atmosphere? I don't remember hearing about it. Maybe signals going around-the-world are different due to interactions with the ground or open top, ---------- What sort of sampling rates do metrologists want or get? ---------- What sort of gear do people use if they want to be able to see this sort of thing? What is the noise like? Is it mostly from wind? How many bits of signal are left on a windy day? Or what should I be asking? -- These are my opinions.
