By combining data collected by the SEIS seismometer operated by the InSight mission on Mars with available orbital data, a scientific team has revealed that Martian seismic activity may be responsible for dust avalanches.

A “Marsquake” with an estimated magnitude of 5 shook the Red Planet on the night of 04/05/2022. The French SEIS instrument, deployed on the ground by NASA’s InSight lander, had a front-row seat. Our teams have transcribed the event in audio.

A was produced thanks to the data deglitching efforts of Grégory Sainton, research engineer at IPGP, and the sonification work of Rémi Lapeyre, head of Insight/SEIS operations at CNES. (© CNES/NASA/JPL-Caltech)
