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.

They will all have blue eyes.
We didn’t detect them but they were always there.
I blame global warming.
We had two quakes in Ferndale Ca yesterday which are obviously connected to Mars...email me for more geological factoids.
Thanks BenLurkin. Probably not new, just have the tools to monitor now.
It’s hungry
Recently?......................
Blink of an eye in cosmic time.
Mars is reacting to the Rover vehicles. The whole planet is alive!

Dead inside: that is incredibly sad. I went through a rough patch 2 decades ago when I was caring first for my mother dying of congestive heart failure, and then my husband dying of Alzheimer’s. They didn’t want to die in a hospital, so my last gift to them was to care for them at home at the end. In between my father died, leaving 6 low income units badly in need of improvement before selling. I did a lot of work on these units with an agreement with my 2 brothers. Then they sold everything and did not pay me my share of the estate or for the work they had agreed to pay me. I felt pretty low for about a year, then began to get involved in public issue and met some good people. I am now 83 and am probably as happy as I have ever been. Please feel free to private mail me if you like. For 10 years I counseled people with severe emotional issues, mostly with success.
