Abstract
Tsunami waves are generated by sea bottom failures, landslides and faults.
The concurrent generation of hydro-acoustic waves (HAW), which travel
much faster than the tsunami, has received much attention, motivated by
their possible exploitation as precursors of tsunamis. This feature makes
the detection of HAW particularly well-suited for building an early-warning
system. Accuracy and efficiency of the modelling approaches for HAW thus
play a pivotal role in the design of such systems. Here, we present a Lattice
Boltzmann Method (LBM) for the generation and propagation of HAW
resulting from tsunamigenic ground motions and verify it against commonly
employed modelling solutions. LBM is well known for providing fast and
accurate solutions to both hydrodynamics and acoustics problems, thus it
naturally becomes a candidate as a comprehensive computational tool for
modelling generation and propagation of HAW.
