Modeling Seismic Recordings of High‐Frequency Guided Infrasound on Mars

Impact - generated seismic signals on Mars

Meteorite impacts will be a key seismic source for probing Mars’ interior during the InSight mission. Maximising data exploitation requires a good understanding of impact-generated seismic ground motions (waves), which has been limited by a lack of observational data and the practical difficulty of replicating relevant martian impact conditions in experiments. The aim of this PhD project is to ...

Infrasound events detected with the Southern California Seismic Network

[1] We examine continuous data from the Southern California Seismic Network from 2003 and identify infrasound acoustic waves from 76 previously undetected events. Using waveform cross-correlation of the signal envelope functions, we determine their relative arrival times and estimate source locations. The waves travel at acoustic speeds of 320 m/s and are observed in seismic records up to 450 k...
