Insight has been on Mars with its seismometer for almost two years now. Has it detected any mars-quakes yet? How often do these quakes seem to occur?

Is there a website where the current number of quakes detected by insight is indicated?

This is the latest catalogue from seismic events recorded by InSight: Mars Seismic Catalogue, InSight Mission; V5 2021-01-04. This report includes seismic events up to October 12, 2020. These documents get periodicaly published, so keep an eye on the page pointed out by @planetmaker on the comments. The robot has measured a total of 1759 Marsquake events as of the report date. Keep in mind that 1034 of those events are of suspicious quality, meaning that the signal may not be attributable to a seism. Setting dubious events aside, in the period of 686 days, the mission has detected about one quake per day. I could not find any website with live data.

  • $\begingroup$ I just added all the recorded frequencys shown in the catalogue; from low to super high ones. I then substracted all records with bad quality to the total and divided the result by the number of days since landing (26 Nov, 2018) till report date to get a daily average. $\endgroup$ Mar 5, 2021 at 16:29
  • $\begingroup$ I doubt that 1000 quakes per day is an accurate number. It's a 1000 measurements with believable data - but most will not contain quakes. Most recorded motion is - according to a very shallow skipping through the literature - attributed to wind influence. $\endgroup$ Mar 5, 2021 at 23:17
  • $\begingroup$ Sorry if the notation confused you, its arround 1 per day. $\endgroup$ Mar 8, 2021 at 1:22

    $\begingroup$ the "per day" or a "daily" is essential to understand the number. I'd actually write it slightley less accurate "Setting dubious events aside, in the period of 686 days, the mission has detected about one quake per day" $\endgroup$ Mar 9, 2021 at 16:03
