Marsquakes

Since Nasa's spacecraft InSight touched down on Martian Elysium Planitia in November 2018, the sensors on board have established for the first time that Mars is a seismically active planet.
Sensors have detected more than 450 tremors, smaller than Earth tremors. Some deeper tremors have been quite strong at 3.0 to 4.0, but they register as puny when they reach the surface. Some tremors may only have been meteorite impacts.
Two tremors were strong enough for them to be traced to their source a thousand miles east of the InSight lander, in the geologically active region of Cerberus Fossae.
Researchers say that the seismic events on Mars are caused by the planet cooling and shrinking plus the movement of tectonic plates.
Dr. Domenico Giardini, of the ETH Zurich, Switzerland, said, "Marsquakes have characteristics observed on the Moon during the Apollo era, with a long signal duration ( 10 to 20 minutes ) due to the scattering properties of the Martian crust."
InSight has also detected water-bearing minerals, indicating that Mars is more moist than the Moon.
The new data will help scientists to understand the structure of Mars's interior and the changes that are taking place there.

Oh wow, I never thought about earthquakes happening on Mars before. That's quite interesting to know. Thanks for sharing!

It could cause problems for finding a suitable site for a Elon Musk fun park and Trump tower. :wink:
