Por John Clinton (ETHZ).
The NASA InSight mission operated a broadband seismic sensor on the surface of the planet from 2019-2022, collecting nearly 2 martian years of high quality data. The SED at ETH was responsible for coordinating the Marsquake Service, that screened all incoming data and managed the seismicity catalogue for the mission. Over 1300 mars quakes were recorded across the planet, including confirmed large impacts and marsquakes reaching up to magnitude M4.5. The majority of these can have distances assigned, and around 50 can be assigned a back-azimuth and hence can be located. Currently the team at ETH is preparing a final revised catalogue for the mission. This talk summarises the key features of the observed seismicity, and includes latest interpretations gleaned from a consistent re-anlaysis of all data. Our understanding is greatly enhanced through waveform de-noising using machine learning. I will also summarise the key discoveries from the InSight science team related to the internal structure of the planet, from crust to core.
