NASA's InSight lander arrived in November 2018 and started listening for Mars' heartbeat, we learnt something really remarkable: Mars is rumbling. To date, InSight has detected hundreds of marsquakes – enough to give us a detailed map of the Martian interior.
Tkalčić and his colleague, geophysicist Weijia Sun of the Chinese Academy of Sciences, wanted to look for quakes that might have gone unnoticed in the InSight data. They used two unconventional techniques, only recently applied to geophysics, to hunt seismic events in the InSight data.
Based on nine templates of known marsquakes, the pair detected 47 new seismic events, coming from a region on Mars called the Cerberus Fossae – a system of fissures created by faults that have pulled the crust apart.
Most of those new seismic events resemble the waveforms of two notable Cerberus Fossae quakes that took place in May and July of 2019, suggesting that the smaller quakes are related to the larger ones.
Then the researchers sought to figure out the cause of the quakes. Their analysis found that there was no pattern to be found in the timing of the quakes, ruling out causes such as the influence of Martian moon Phobos.
Previous analysis of features on the surface of Mars at the Cerberus Fossae found that the region had been volcanically active recently, within the last 10 million or so years.
The activity identified by Sun and Tkalčić, attributed to the repetitive movement of magma in the Martian mantle, also suggests that Mars is more volcanically and seismically active than we thought.

"We" who?
When you look for Mars quakes, you find Mars quakes…amazing.
NASA’s InSight lander measures one of the biggest and longest marsquakes yet – with tremors on the Red Planet lasting nearly 1.5 HOURS

LOL!
I find it interesting-
For a long time Mars was assumed to be dead inside, like me.
In before the “In before the Dune worm pictures” comments.
Interesting. One of the theories/explanation for the height of Olympus Mons is that Mars had very limited tectonic activity allowing the volcano to continue to grow in place.
Dude, don’t even think that. Look for reasons to live. They are everywhere.
“Wrong darn rec room!”
Seems like only yesterday.......................
TOO LATE!...................
Very cool!
That explains it.
The rover needs to shuffle its feet (wheels?) when it walks.
Somehow the quakes are bound to be Trump's fault.
Yeah, shuffle, that will help.
The upside, is that when the left realizes the potential for spice, they might forget about changing their genders in favor of Mars exploration.
God can bring you life.
“
1 You were made alive when you were dead in transgressions and sins, 2 in which you once walked according to the course of this world, according to the prince of the power of the air, the spirit who now works in the children of disobedience; 3 among whom we also all once lived in the lust of our flesh, doing the desires of the flesh and of the mind, and were by nature children of wrath, even as the rest. 4 But God, being rich in mercy, for his great love with which he loved us, 5 even when we were dead through our trespasses, made us alive together with Christ (by grace you have been saved),
