We show simulations of tsunami propagation from asteroid-generated airbursts. We then present a 1D model with an explicit solution to understand the unexpected results. The model is then extended to explore the effects of dispersion and compressibility. We end with a discussion of appropriate tools to study the more serious case of an asteroid that impacts the water.
This work builds on a long-running project to simulate earthquake generated tsunamis. The software uses an AMR adaptive strategy combines with a Cartesian grid treatment of ocean boundaries, using real bathymetry from databases.
