Query: Ultralow frequency acoustic resonances and its potential for mitigating
  tsunami wave formation   Bubbles display astonishing acoustical properties since they are able to
absorb and scatter large amounts of energy coming from waves whose wavelengths
are two orders of magnitude larger than the bubble size. Thus, as the
interaction distance between bubbles is much larger than the bubble size,
clouds of bubbles exhibit collective oscillations which can scatter acoustic
waves three orders magnitude larger than the bubble size. Here we propose
bubble based systems which resonate at frequencies that match the time scale
relevant for seismogenic tsunami wave generation and may mitigate the
devastating effects of tsunami waves. Based on a linear approximation, our
na\"ive proposal may open new research paths towards the mitigation of tsunami
waves generation.
