Eerie rumbles are coming from Mars' interior

NASA's Insight lander has recently picked up the telltale signs of seismic activity on the Red Planet.
The space probe, which landed on Mars back in November 2018, uses a special dome-shaped device deployed on the planet's surface to listen out for signs of seismic activity.

Known as the Seismic Experiment for Interior Structure (SEIS), the device is incredibly sensitive to the point where it has to be protected from the elements to ensure that it keeps working properly.

This latest detection comes during a time when calmer winds have made it easier to pick things up.
Seismic activity on Mars is often referred to as a Marsquake, however the Red Planet does not have the same tectonic plate system as the Earth, so the quakes are not caused by the same processes.

The precise source of these seismic events in fact continues to remain something of a mystery - all we know is that something has caused a sudden release of energy in the planet's interior.

The most recent quakes seem to be centered around a region of Mars known as Cerberus Fossae which is also the site of several other quakes that have been picked up in the past.

Further studies will no doubt be needed to find a definitive explanation for the phenomenon.

Quote: "Although these rumblings have sometimes been called "Marsquakes" the planet is not believed to have a similarly active tectonic system like Earth's that causes earthquakes." And this unknown tectonic system is said to be responsible for the creation of the Valles Marinaris. They don't know what really caused its formation. Years ago I posted an alternative explanation: a socalled 'grazing comet': LINK

More info... NASA’s InSight lander has detected two strong, clear quakes originating in a location of Mars called Cerberus Fossae – the same place where two strong quakes were seen earlier in the mission. The new quakes have magnitudes of 3.3 and 3.1; the previous quakes were magnitude 3.6 and 3.5. InSight has recorded over 500 quakes to date, but because of their clear signals, these are four of the best quake records for probing the interior of the planet. Mars NASA Gov

Pennsylvania? My god, we've stumbled on a conspiracy! Study it out.

Occam's Razor would suggest that the rumbles are caused by Elon Musk's Martian Hyperloop network.
