The faint seismic signal, detected by the lander's Seismic Experiment for Interior Structure (SEIS) instrument, was recorded on April 6, the lander's 128th Martian day, or sol. This is the first recorded trembling that appears to have come from inside the planet, as opposed to being caused by forces above the surface, such as wind. Scientists still are examining the data to determine the exact cause of the signal.

NASA told us Mars was not geologically active.
Now it's saying it is.
Why should we believe them? They obviously don't have a f# clue.

The interpretation of improved data from current Mars missions, and improvements in our theoretical understanding of the processes at work on the planet, are causing a strong trend towards consideration of Mars as a geologically dynamic planet. Evidence of geologically recent and even what is essentially present-day fluvial activity seems particularly convincing. Although Mars is clearly near the end of its volcanic life, there is a case for Mars not being volcanically extinct, though the chances of seeing an eruption during our lifetimes are not good. The episodic nature of activity on martian volcanoes suggests that they may not be the best places to look for evidence of the long-term survival of biosystems. However, the accumulating evidence that large-scale, long-lived subcryosphere aquifers may be common even today improves the odds that at depths of a few kilometres we might find surviving organisms from earlier, more benign periods of martian history.

So marsquakes are not caused by tectonic plate movement like on earth? Marsquakes are just echoes of various events like landslides, CO2 geisers, and residual volcanic activity?
