Science Alert!!!
"NASA Just Recorded a Quake on Mars For The First Time, And The Audio Will Haunt You!!!
MICHELLE STARR 24 APR 2019
NASA's InSight Mars lander may have recorded its first 'Marsquake' - seismic tremors, faint but unmistakable deep in the belly of the red beast.
Early analysis has confirmed that the tremor did originate inside the planet, as opposed to atmospheric influences such as wind. Now seismologists are hard at work to narrow down precisely what caused it.
Quakes on Mars, just like quakes on Earth, can reveal details about the planet's interior. InSight, which landed on Mars in November last year, is a mission specifically designed to study the guts of Mars. It's equipped with a range of instruments to take measurements of the planet's temperature, rotation and seismic activity.
Most of the data collected by the Seismic Experiment for Interior Structure (SEIS) instrument to date has consisted of background noise, but on April 6 - Sol 128 of InSight's mission - the instrument finally registered what the team had been looking for.
"We've been waiting months for a signal like this," said SEIS team lead Philippe Lognonné of the Institut de Physique du Globe de Paris (IPGP).
"It's so exciting to finally have proof that Mars is still seismically active. We're looking forward to sharing detailed results once we've had a chance to analyse them."
The waves of a strong enough tremor can act a bit like a planet-sized ground-penetrating radar, only with seismic waves instead of electromagnetic. As these waves propagate through a planet, they can slow down as they move through certain materials, or bounce off others, letting seismologists infer the interior composition.
Sadly, the Sol 128 event was too faint to tell scientists anything about the structure of Mars's interior, and here on Earth it would have been lost among the constant grumblings of tectonic activity. ut it does demonstrate that, even though Mars isn't tectonically active, there is seismic activity - raising hope for a stronger tremor down the line. Especially since three other, fainter seismic signals were also recorded on Sol 105, Sol 132, and Sol 133."

Thank you, my friend Sgt (Join to see) for posting the news about the Marsquake with an understandably out of this word sound :-)
Most likely, Mars has experienced Marsquakes in the past in the vicinity of fault-lines between the tectonic plates of Mars. Without significant structures or bodies of water it is more challenging to observe. Of course volcanoes would help identify regional activity on our neighboring planet :-)

Thank you for the outstanding graphic of the Valles Marineris LTC Stephen F.. Our "Insight" mission probe is actively doing its job! There have been questions as to whether Mars does, indeed, have tectonic plates like those of Earth... This probe, "Insight" hopefully will give us better data to understand the underpinnings of Planet Mars...
