Seismology for other planets

As we mentioned before, the foundation of seismology is the Hooke's law and the Newton's 2nd law. We expect these laws to work in other celestial bodies too. Therefore we can use seismological principles we obtained by studying the Earth to other places.

Basin-forming impact: Caloris impact and antipodal geological disruption on Mercury

see paper "Seismic effects of the Caloris basin impact, Mercury" by Lu et al. on PSS 2011

Previously, it was thought focused body wave and Rayleigh are responsible to generate the antipodal geological disruption for the Caloris basin impact. Assuming a thin solid mantle overlying a liquid core, we found that (1) body wave contribution is negligible; (2) focused mantle guided wave arrives at the antipode faster (~7km/s velocity) and can generate high stress; (3) slower Rayleigh wave with inverse dispersion comes later with large amplitude. The mantle guided wave is a newly proposed mechanism to generate the geological disruption at the antipode.
