![Vertical component spectrogram of event S1094b, caused by a meteoritic impact (Posiolova et al., 2022). The bottom two panels show P- and S-wave spectra in several 60 second time windows following the direct arrival. The spectral shape stays consistent throughout the inital 150 and 230 seconds after arrival of the phase, indicating an equipartitioning of seismic energy with no significant viscoelastic attenuation. -- [astro-ph.IM]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/07/Discrimination-of.png?resize=1200%2C719&ssl=1)
[astro-ph.IM] The NASA InSight mission observed over 2000 marsquakes in the course of its three year mission. These quakes varied in magnitude between 1.5 and 4.5, as well as in […]

Marsquakes May Help Reveal Whether Liquid Water Exists Underground On Mars
If liquid water exists today on Mars, it may be too deep underground to detect with traditional methods used on Earth. But listening to earthquakes that occur on Mars — […]
