Infrasonic, acoustic and seismic waves produced by the Axion Quark
  Nuggets
  We advocate an idea that the Axion Quark Nuggets (AQN) hitting the Earth can
be detected by analysing the infrasound, acoustic and seismic waves which
always accompany the AQN's passage in the atmosphere and underground. Our
estimates for the infrasonic frequency $\nu\simeq 5$ ~Hz and overpressure
$\delta p\sim 0.3 ~$Pa for relatively large size dark matter (DM) nuggets
suggest that sensitivity of presently available instruments is already
sufficient to detect very intense (but very rare) events today with existing
technology. A study of much more frequent but less intense events requires a
new type of instruments. We propose a detection strategy for a systematic study
to search for such relatively weak and frequent events by using Distributed
Acoustic Sensing and briefly mention other possible detection methods.
